A co-ancestry (or kinship) coefficient is the probability that an allele randomly drawn from one individual is identical by descent (autozygous) within the pedigree to an allele drawn from another individual and is equivalent in value to the inbreeding coefficient for these individuals' prospective offspring (Hartl and Clark 1989).
