unspecified parent
brentp opened this issue · comments
given a pedigree with a missing parent like:
fam mom 0 0 2 2
fam kid1 0 mom 2 2
fam kid2 0 mom 2 2
somalier will give an expected relatedness of 0.25 to kid1 and kid2. It's probably more common that they will have the same father and therefore have an expected relatedness of 0.5.
