Re: [jacksongenealogy] DNA Testing and Paternity
- You don't say if the offspring was a male. If the male had a Y
chromosome matching the father, he could not get that from his
mother. Of course, he would also match any male related to the father
and having the same surname.
If you could do an autosomal DNA test on the son or daughter , whoever
that might be, they would have an unusually high fraction of homozygous
alleles. They would have long stretches of chromosomes where both arms
of the chromosome ( pairs of markers) were identical. This would be
like the test on gedmatch.com called "Are your parents related to each
If instead you have only grandchildren or great-grandchildren to test,
the result would be much less definitive - but still detectable.
