Inbreeding in the united states.

Inbreeding causes the number of direct ancestors in a pedigree to differ from 2 t (where t is the number of generations in the past). For example, the progeny of first cousin matings have six, rather than eight, great-grandparents. As inbreeding affects the number of ancestors in a pedigree, it results in modified organismal coalescence times.

The inbreeding coefficient (denoted by F) of an individual is the probability that two parental alleles sampled at a random locus in the genome are IBD. Thus, inbreeding coefficient of an individual is the kinship between his or her parents. In addition, between one and oneself (or between monozygotic twins) ϕ = ( 1 + F) / 2 ( Wright 1922 ).
