double dagger]) F = Coefficient of inbreeding estimated using formulae developed by Busbice (1969).
Malecot's coefficient of relationship is twice the fixation index, or coefficient of inbreeding.
On the whole, the results support the theoretical expectation that inbreeding depression should be directly proportional to the coefficient of inbreeding, F, if all loci combine additively (Falconer 1989).
Estimation of the Average Coefficient of Inbreeding from Demographic Data
The level of inbreeding in a population can be measured by the coefficient of inbreeding (F), which is the probability that the two alleles at a locus in an individual are identical by descent (IBD).
To investigate fitness differences between selfed and outcrossed progeny, the coefficient of inbreeding depression 6) was calculated according to Lande and Schemske (1985),
That is the value of the inbreeding effective size in the first generation in this case because, if there are equal number of sexes, a proportion 2/N of matings are expected to be between full-sibs and thus the expected coefficient of inbreeding is 1/2N (Ugarte et al.
