Gedmatch Homozygosity Test (Are your parents related?)

[MfA_]

Since you inherit half of your DNA from each of your parents, it stands to reason that large blocks of SNPs where both alleles are the same would be an indication that your parents each inherited that block from the same ancestor. These are called 'Runs of Homozygosity' (ROH). There are other utilities available that look for ROH for other purposes, but this analysis is specifically aimed at determining how closely related your parents might be.

Sibling 2350 cM
Half Sibling 1600 cM
First Cousin 800 cM
Second Cousin 200 cM
Third Cousin 100 cM
Fourth Cousin 50 cM
Fifth Cousin 25 cM



My Results:

Largest individual segment of SNPs with greater than 500 matches: 0

Total autosomal SNPs in segments with greater than 500 matches: 0

Largest Single-Block Genetic Distance = 0 cM

Total Genetic Distance = 0 cM

Nope, thought they would have been distant. But wasn't to be..

btw My Gedmatch code is M333431, for anyone to check of shared segments.
