WebJan 23, 2024 · The scientific answer according to Science Direct is, " The coefficient of inbreeding ( F) for a child of a consanguineous marriage is the probability that the child receives two alleles at a given locus that are both from the same ancestor and are, thus, identical by descent (autozygous). " So why does this matter? WebThe inbreeding coefficient can have any value between 0 and 1.0 although it is unlikely for it to have a value much above .5 in most herds of livestock.
