WebInbreeding is a cumulative phenomenon and in the course of successive generations it increases homozygosity by 50% and reduces heterozygosity by 50% in F1, 25% in F2, 12.5% in F3, and 6.25% in F4. What causes homozygosity? You inherit two alleles for each gene. One comes from your biological mother and one comes from your biological father.
