inbreeding coefficient (F)
the probability that an individual has a pair of alleles that are identical by descent from a common ancestor; the proportion of loci that carry alleles that are identical by descent from a common ancestor ...
[edit] Inbreeding coefficient
The inbreeding coefficient, F (see also F-statistics), is one minus the observed frequency of heterozygotes over that expected from Hardy-Weinberg equilibrium.
Inbreeding coefficient
The probability of homozygosity by descent (having common ancestors). The probability that a zygote obtains copies of the same ancestral gene from both its parents because they are related. The probability of autozygosity.
In a long career, he invented much of the theory of genetic drift (also known as the "Sewall Wright effect") and developed the inbreeding coefficient and many of its applications.

FIS (inbreeding coefficient) is the proportion of the variance in the subpopulation contained in an individual. High FIS implies a high degree of inbreeding.
