Document Summary

Effect of p on the efficiency and ultimate result of non-random mating. The value of p is the sum of paa and half of h, 0. 10+0/2=0. 10. In general, nonrandom mating results in stabilization of pfinal around the original value of p, and number of heterozygotes decreases after each generation. Due to limited food sources, the finches with specialized beaks were favoured (e. g. big beaks for big seeds). Nonrandom mating happened (i. e. a finch only mate with another finch with a similar diet and similar beak size), and as a result, the number of homozygotes increases. We can predict that loss of heterozygosity will happen much slower. Nonrandom mating is not the same as inbreeding. Inbreeding can be considered as a type of nonrandom mating based on genotype differences. Nonrandom mating can happen whenever there are favoured/discriminated traits in selection of reproduction partners. The bigger that the sample size is, the easier it is to draw conclusions.
