WebInbreeding causes a loss of heterozygosity with no expected change in allele frequencies. … As alleles are lost, homozygosity necessarily increases. Within any given small population, mean fitness may increase or decrease, depending on whether deleterious or advantageous alleles are lost by drift. Does genetic drift decrease genetic diversity? WebInbreeding leads to low heterzygosity. A common crop breeding strategy is to have two inbred lines (homozygous at most loci) and then cross them to make a hybrid that is heterozygous at many loci and which has hybrid vigour (the payoff from having very high levels of heterozygosity).
