WebThe INBREEDING COEFFICIENT, F,is used to gauge the strength of inbreeding. F= probability that two alleles in an individual areidentical by descent(IBD). Fstands for fixation index, because of the increase in homozygosity, or fixation, that results from inbreeding. Note: two alleles that are identical WebIncreased homozygosity—the inheritance of two identical alleles at a certain genetic locus—is the effect of this. Inbreeding can increase homozygosity, however this can have unfavourable effects on the population’s genetic diversity and the expression of harmful recessive genes.
