WebNon-random mating won't make allele frequencies in the population change by itself, though it can alter genotype frequencies. This keeps the population from being in Hardy … WebGenotype frequencies change; What I don't understand is the second point. If the genotypes' frequencies change, shouldn't the frequencies of alleles change as well? Furthermore, I don't really understand either how this is supposed to be linked to a negative density-dependence case... Any help is welcome!

WebThe cross between the true-breeding P plants produces F 1 heterozygotes that can be self-fertilized. The self-cross of the F 1 generation can be analyzed with a Punnett square to predict the genotypes of the F 2 generation.
