DNA CONTAINS BLUE PRINT FOR THE BODY OF THIS LIFE OF A LIVING BEING.....BUT RELATES TO THE ANCESTORS OF LIVING BEING....HOW CURRENT GENETIC SCIENCE RE Posted by Vishva News Reporter on April 19, 2003 |
As per veD a body of a living
being in current life is made to experience the
kARm-fl (which
could be puANy
= good or paapi
= sinful) dividends of past kARm) of the
kARm performed in previous lifetimes which one cannot even
count....current genetic science tell us that the current body is made from the
information coded in one's DNA from many many ancestors....so how does the
veDik statement relates to the
current science statement....PVAF would like

DNA analysis has solved murder cases and historical puzzles. Now it's
being applied to the most personal mysteries of all:
Exactly
who is my family?.... Where did we come from?
As the cost of genetic testing comes down, thousands of people are finding
new opportunities within their reach — and wrestling with new questions as well.
Twenty-five years after "Roots" brought the genealogical quest home to millions
of television viewers, "Genetic Genealogy" explores the next family
frontier......

REDMOND, Wash., Jan. 16 — I
clutched the phone and started the trans-Atlantic countdown: Thanks to a
mail-order DNA test, I was about to find out whether my Irish “cousin” was
really my cousin. On the other end of the call was my cousin’s
fiancée, who read off 10 numbers while I compared them. The first number?
Check. The second? Check. So far, so good. |

MY QUEST was coming to a climax
after four years of researching my Boyle family tree.
Since 1997, I’ve traced
scores of relatives, living and long-gone — but the trail hit a dead end
three generations back.
My great-grandfather, Michael Boyle, fled Ireland’s County Clare for
America in 1847, during the depths of Ireland’s potato famine. He left no
records that could point to his precise birthplace or his kin. He did,
however, leave behind an enduring clue: his genetic code.
A specific section of his DNA, passed down from father to son, could
confirm whether I was right on my guesses about a common ancestry with
Boyles who still live in County Clare. So I became a genetic genealogist,
using a technology that is transforming one of America’s most popular
pursuits.
HOW IT WORKS
DNA tests have been around for many years, but it’s been only in the
last year or so that ordinary people could get their own genetic family
profile for less than $300 a test. |

The home test kit can be ordered
through the mail or over the
Internet. It
comes with a scraper or brush to scrub a sample of cells from the inside of
your cheek.
You send back the sample, along with your check and the release
forms. Within a month or two, you get the results in the mail: a series of
numbers that represent key chemical “markers” within your DNA, displayed on
a form suitable for framing.
One type of test traces your maternal line, based on slight
variations in mitochondrial DNA. This brand of DNA changes very slowly,
which means it’s of limited usefulness for genealogical purposes. The best
you can do is determine your ancestral “clan” from a couple of dozen around
the world.
Another type traces the paternal line through Y-chromosome DNA, which
is passed down from father to son. This test can be conducted only on males,
and taken in isolation, the results don’t tell you much. But two sets of
results can be used to estimate your chances of being related to someone
else on a scale of hundreds of years.
(An interactive graphic titled “Genetic Fingerprints” provides additional
detail.)
In 1998, such a test indicated that Thomas Jefferson or one of his
relatives fathered at least one child born to a slave at Jefferson’s
Monticello estate. Last summer, I used the same kind of Y-chromosome test in
my own family search.

DNA identification techniques have shed new light on crimes and
controversies that go back as far as 200 years. Laboratory
analysis can match victims with potential assailants, identify
unknown remains or even determine the relationships between
historical figures. Click on the topics above for details on
five of the best-known cases.
SEPT. 11
ATTACKS
More than 12,000 DNA samples have been taken in the effort to
identify human remains recovered from the wreckage of the World
Trade Center. DNA readings from the remains are compared with
cheek swabs from relatives or samples taken from personal
effects such as toothbrushes or unwashed clothing. By the end of
2001, labs had identified 94 victims based solely on DNA, and
the pace of identification is increasing.

GREEN RIVER
KILLINGS
Since 1982, 49 Seattle-area women have died in a collection
of cases known as the Green River killings. Advances in DNA
technology finally led to an arrest in November 2001, when tests
found a match between minute samples recovered from the remains
of four Green River victims and a sample of saliva taken in 1987
from Gary Leon Ridgway, a 52-year-old truck painter. Ridgway has
pleaded not guilty to the killings.

BOSTON
STRANGLER
Eleven Boston-area women were strangled between 1962 and
1964. Blue-collar worker Albert DeSalvo confessed to the crimes.
He later recanted, but the "Boston Strangler" label stuck.
DeSalvo was himself killed in prison in 1973 while serving a
sentence on unrelated charges. Now the mystery has been revived:
In December 2001, scientists said they found no match between
foreign DNA recovered from the Boston Strangler's last victim
and samples from DeSalvo's exhumed remains.

THE
INNOCENCE PROJECT
Between 1989 and 2001, 100 convicted felons have been
exonerated on the basis of DNA evidence under the auspices of
the Innocence Project. The 100 include Idaho death-row inmate
Charles Fain, who was set free in August 2001, nearly 18 years
after his wrongful conviction on charges of kidnapping, rape and
murder. Spurred by such cases, the U.S. Justice Department had
planned to spend $750,000 for DNA testing of convicts, but that
money was diverted to help identify Sept. 11 terror victims
instead.

THOMAS
JEFFERSON'S KIN
Even while he lived, America's third president was rumored to
have carried on an affair with Sally Hemings, a slave at his
Monticello estate. In 1998, Y-chromosome samples provided by the
Jefferson family and descendants of Sally Hemings showed that
there was a common male ancestor dating to Thomas Jefferson's
era. Many saw the DNA findings as confirming the rumors, but the
Jefferson family pointed out that Hemings' children could have
been fathered instead by one of the president's relatives.

TIME OF TESTING
My case was a good candidate: My research led me to the coastal town
of Quilty, where almost half of the county’s recorded Boyles lived in the
mid-1800s. One family there had a string of Boyles named Austin — which was
a common name in my family as well. Internet contacts, phone calls and a
visit to Ireland in 1999
solidified my connection with this family, which had relatives spread across
the globe. |

I made contact with one of the Austins in London over the phone, and
he played host to my daughter for an afternoon during her first trip to
Europe. Austin’s long-lost Australian cousin, Martin O’Boyle, sent me a
history of the Quilty area.
In July, Martin and Austin agreed to be tested at MSNBC’s expense —
with Martin taking a mail-order test from Houston-based Family Tree DNA, and
Austin taking a similar test from Oxford Ancestors in England. I took the
test from both companies, to see how the procedures and the results
compared.
Martin and Austin were as intrigued to hear about each other as they
were to hear about my DNA project. “I haven’t seen Austin in about 16
years,” Martin marveled.
Austin and his fiancée, Pura Bolea, were taken by the idea that
technology could trace a long-hidden relationship to someone across an
ocean. “It has that sort of ‘ooh’ effect,” Bolea said, “like a little kid
looking for treasure.”
WAITING AND LEARNING
|

The treasure
hunt — for genealogists and the companies offering the DNA services — is
just beginning. Over the past year, Family Tree DNA and Oxford Ancestors
have each amassed a database of more than 2,000 samples.
“The tests have really taken off,” said David Ashworth, chief
executive officer of Oxford Ancestors. “There’s been an explosion, to be
honest.”
One of Ashworth’s biggest challenges is explaining the limitations of
genetic genealogy.
“It can get very complicated, and the average man in the street wants
to know yes, no, we have a common ancestor — and you can’t give them that
information,” he said.
Instead, you get fuzzy statistics. If two men have identical results
on a 12-marker test, they’re almost certainly related, said Bennett
Greenspan, founder of Family Tree DNA. But there’s only a 50 percent chance
that their common ancestor lived within the past 14.5 generations, or
roughly 600 years.
If just one marker is different, that means there has been a change,
or mutation, in the Y-chromosome since the common ancestor lived — pointing
to a more distant relationship.
“You can expect one mutation. That’s rolling the dice,” said Doug
Mumma, a genealogist who has arranged for more than 30 DNA tests of other
Mummas. Two variations, however, is “pushing it.” And when three or more
markers are different, Mumma considers the person to be unrelated.
|
|
|
|
|
|

That can come
as hard news — particularly if a test indicates that there was an
undisclosed adoption or marital infidelity. Mumma came across one such case.
“It’s like someone hitting you in the chest,” he said. “It takes the
wind out of you. That’s where you want to keep confidentiality, particularly
if your parents or grandparents are still living.” |
|
|
|
|
Vicki Michel, a law professor and bioethics consultant, says that’s
one of the risks of genetic genealogy — even for Austin, Martin and me.
“Suppose that you had created a relationship with these people. If
you all connected and felt like family, would that all disappear if it
turned out that you weren’t genetically connected?” Michel asked. “Or do
relationships have to do with a history of being together, of sharing
experiences?”
Genetic testing poses a “big unknown” for family relationships,
Michel said.
“I don’t think there’s anything wrong with exploring the unknown,”
she told me, “but I think it’s important for people to be aware that when
you go into the unknown, sometimes you like what happens, and sometimes you
don’t.”
It was a sobering thought, even as I waited for the results from my
own project.
MOMENT OF TRUTH
The white envelope from Oxford Ancestors came back in early
September. Over the weekend, I studied the numbers and pored through pages
of scientific explanations. The following Monday, I picked up the phone and
called Austin in London. He was away at work, but Bolea pulled out the
results from his white envelope. |
|
|
After a DNA specimen is
tested, Oxford Ancestors provides a color-coded chart of 10 genetic markers
within the Y-chromosome, as shown in this sample.
|
|
The first two numbers — 14 and 12 — matched. The third was different:
25 for Austin, 24 for me. That’s OK, I thought. It’s a roll of the dice.
The fourth numbers were the same. We were back on track.
Then Bolea read off the fifth number. No match. The sixth number. No
match. The rest of the numbers were identical, but by then I felt as if I
had missed the lottery. “There might be a distant relationship,” I told her
wanly. I promised to call back and discuss the results further with Austin.
That was Sept. 10. The next day, four airliners were hijacked, the
World Trade Center collapsed and the world changed. It was months before I
got back to Austin.
When I had time to muse about the DNA results, I wondered if three
mismatches out of 10 was really that bad. But on Sept. 19, I received the
confirmation in an e-mail from Bennett Greenspan at Family Tree DNA, who
compared my results with Martin’s.
“He and you did not match,” he wrote. The full list of numbers showed
that five of the 12 markers were different. Based on those readings, I had
more in common with Doug Mumma than with Martin O’Boyle.
Austin and Martin clearly were descended from a different strain of
Boyles. Even though we knew each other only through telephone lines and the
Internet, I felt as if there had been a divorce or a death in the family.
Then came consolation.
REVISITING THE RELATIVES
After the holidays, I finally got back to Austin and Martin. When I
discussed the results with Austin, the first thing he asked was, “Are you
sure?” |

He noted that his grandmother as well as his grandfather
was a Boyle, and that the line of relationship might go through the
grandmother’s side. There were male cousins on that branch who might be
willing to take the DNA test. And if that lead didn’t pan out, there were
plenty more Boyles to go, he said.
“Even when I was growing up, the amount of Boyle families (in Quilty)
that were not related was six or seven,” he offered.
Then Austin asked about Martin and his family: Where exactly does he
live? Was Martin’s brother still alive? When I got in touch with Martin on
the other side of the world, he had questions as well: Were there any maps
of County Clare on the Internet? Does Austin use e-mail?
So I’ve found myself drawn into a circle despite the DNA results.
Austin is helping me get in touch with other Boyles in America and Ireland.
I’ve sent Martin pointers to Clare-related Web sites, and I’m helping the
two long-separated cousins stay in closer touch.
After all, isn’t that what families are for?
