Does anyone who is FF tested match me on all of these SNPs?

[1798]

I checked out my son's FF results with mine.
My son Me
AA 112,612 112,239
GG 130,548 130,796
TT 112,473 112,796
CC 131,312 131,411
AG 82,211 82,867
TC 81,990 82,981
AC 18,743 19,103
TG 18,765 18,914

I noticed also that I have a lot of the same X SNP alleles as my son. I don't know how that is.

[1798]

Can anyone explain why I match my son in SNPs but the chromosome positions are different? Here is a sample.

Here is a sample from my son and my X results. We have two different mothers passing on two separate X chromosomes so how is that we match on a lot SNPs?

You have to compare the results with the same build format.

rs4477212
Build 36 = 72017
Build 37 = 82154

In FTDNA, you can download result with Build 36 or Build 37 format. If you ever use David Pike's tools, it's obvious written there that data files based on different reference standards (such as Build 36 versus Build 37) should not be directly compared without first converting to a common standard.

Thanks. I have downloaded the two of them. It still doesn't answer the question. Why has my wife the same SNPs as I have?
We are not related.

Wikipedia
"A large gene pool indicates extensive genetic diversity, which is associated with robust populations that can survive bouts of intense selection. Meanwhile, low genetic diversity (see inbreeding and population bottlenecks) can cause reduced biological fitness and an increased chance of extinction, although as explained by genetic drift new genetic variants, that may cause an increase in the fitness of organisms, are more likely to fix in the population if it is rather small."

You do realize that wikipedia explanation is about coding gene, right ? While majority of SNPs that have been used in ancestry purpose are non coding.

I know that my 16 GG grandparents came from within a 10 mile radius of my home. That is the gene pool where my autosomal dna comes from.

You are lucky to have such easy paper trail research within reach. I just wish I could find all 16 of mine, which is part of what I hope to get out of FF follow up. How about your next 32. Were they from further afield?

Why do you think if you are not related to your wife, then you will not get the same allele ? I give you an example ; there are just 3 possible result for rs4477212 which are AA, AG, or GG. So everyone in the world will get one of those 3 possible values.

How many identical SNPs allele (in one segment, in a row) that you both have ? 300, 400, 500 ? If you just have identical allele less than 300 SNPs in a row then you are not related to her. Well, FTDNA threshold is 7 cM (about 700 SNPs) in first segment and 5 cM (about 500 SNPs) in next segment to declare related.

I can't edit my previous post ?

Well sorry, I mix up something in previous post.

Gedmatch use 3 cM as a minimum threshold, 23andme use 7 cM (about 700 SNPs) in first segment and 5 cM (about 500 SNPs) in next segment, while FTDNA threshold is at least 500 SNPs in first segment and a total of 20 cM to declare two people related.

The church records don't go back far enough to establish a paper trail to all of the 32 but I have some of them.The names are still in the same townlands showing in the Hearth Money Rolls of the 17th century.

My son and I have one shared X match!!!!

[Parameswara]

My son and I have one shared X match!!!!

If you came from isolated area then it's a common thing. You said that you have 16GG grandparents came from within 10 miles radius from your home. So, it's possible if you test some random people from your area then the result will be related.

By the way, how many cM you share with your son in X Chromosome ?
