Local populations are also sometimes called Mendelian populations or subpopulations . The local populations is usually the unit of measure when we talk about populations. Mating In sexually reproducing organisms, genotypes are not transmitted to the next generation. Genotypes are broken up by segregation and recombination and assembled anew in each fertilization. Which gametes come together is affected by the opportunity for organisms of reproductive age to come together in the previous generation.
Many factors affect the opportunity to breed.
Random Mating Specific mating likelihoods are determined, at least in part, by the frequency of the alleles in the population. Chance AA mates with aa is related to the frequency of each genotype in the population. This assumption is necessary mathematically to simplify the model. Hardy-Weinberg Principle Genotype frequencies are determined in part by the pattern of mating. 2 A and a are the gametes of the prev.
