Recall that the coefficient of consanguinity (CC) between two individuals or gametes is the probability that alleles chosen randomly from each of the two individuals are identical by descent (Crow and Kimura 1970).
[g.sub.ij] The coefficient of consanguinity (CC) between two gametes native to Di and Dj of the same patch.
Assume outcrossing occurs to relatives with coefficient of consanguinity r, (the coefficient of consanguinity of two mates equals the inbreeding coefficient of their progeny; for example, it equals 1/2 for inbred full sibs, 1/4 for outbred full sibs, and 1/8 for outbred half-sibs).
