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.
