6.2 Inbreeding

  Inbreeding an occurring situation in nature, with many species using this method of reproduction as opposed to random mating. Non-random mating does not in itself affect evolution because it does not change allele frequencies, but it does affect the Hardy-Weinberg Equilibrium. Non-random mating is the most common in the form of inbreeding. Inbreeding causes the production of an excess of homozygotes. In class, we learned that when we have an over excess of homozygotes, we cannot predict genotype frequencies by multiplying allele frequencies anymore. Inbreeding can be predictable if we know the inbreeding coefficient.     Some benefits of inbreeding that may lead to the evolution of assortative mating is that it enables an individual to be more selective with certain traits and providing a smaller gene pool to select from. An example of this would be in dog breeding. If a dog is homozygous for a specific gene, like AA, then it can only pass the A allele to its offspring....
