  • My dads results and I show no match? what does this mean

    So I've done a One-to-one Autosomal Comparison on gedmatch between my dad (A015695) and myself (A487395) and it shows we have No shared DNA segments found.
    Being my father I would expect to see something in the 3000-3500cM range.

    Is this telling me my dad isn't my dad or is it just that I share none of the matching DNA and have perhaps got more of my mums?

    If I use our same kit numbers and run a People who match both, or 1 of 2 kits, we share some similar ancestors as far back as 4 generations

    Are you both tested with Ancestry?
    If so does Ancestry show you as a match at their site?

    We have two of each chromosome, 46 single chromosomes, 23 pairs
    We inherit 50% of father and 50% of mother, exactly.
    You will match each parent along the entire length of each chromosome
    You can not inherit more of one parent then the other.

    If you do not match your dad along the entire length of each chromosome (roughly 3400cM in total), then sorry to say, he is not your biological father.
