Definition of Inbreeding Coefficient F



Inbreeding coefficient (F) is the probability of the two alleles to be identical by descent in an individual. It is also stated as the possibility of two alleles of a given gene in an individual to be identified as both the copies are descended from the mutual ancestor.

 


The coefficient of inbreeding (F) is used to determine the strength of inbreeding. Inbreeding is defined as the phenomenon of the mating of those organisms which are closely related to each other with respect to their ancestor. F represents the fixation index which states the expected level of heterozygosity in a population in terms of statistics. It can also be used to define the effective size of the population.
