For a real inbreed to occur, the mating individuals should be more closely related than those drawn by chance from the population. In conclusion, given enough time, inbreeding (and genetic drift as well) has the effect of eradicating heterozygotes from the population. Share Improve this answer

WebInbreeding increases the frequency of homozygous genotypes and decreases the frequency of heterozygous genotypes in the population. The offspring of consanguineous marriages … WebAs inbreeding increases, the probability of being homozygous for one (or more) of these lethal alleles also increases, causing fitness to decline. However, as those lethals begin to …
WebMice used in lab experiments are often inbred, as the similar genetic structures enable experiments to be repeated. Controlling outcomes is also the motivation for inbreeding in … WebSep 19, 2014 · Inbreeding increases homozygosity. By that, we mean that if there are two (or more) alleles in the population for a gene, the frequency of AA and aa will increase, and Aa and aA will decrease. If a dog is homozygous for AA, then it can ONLY pass the A allele on to its offspring - it is "fixed" for the A gene.

But continued inbreeding results in reduced fertility and productivity in animals. This is called inbreeding depression. This can be overcome by crossing these animals with unrelated superior animals of the same breed having no common ancestors. This is called out-crossing. green thing on fingerWeb1.
