Document Summary
Genes in populations: fundamental components of genetics. But 2n totals of any given gene: a locus may be represented by any number of alternative alleles, hardy-weinberg principle. A fundamental relationship between allele frequencies and genotype frequencies. Populations will, after one generation of sexual reproduction, produce a stable proportion of individuals of each genotype in the next generation, as long as. Parents are chosen from the population randomly and mate randomly. Males and females have identical allele frequencies. One can predict the stable genotype frequencies in successive generations after one round of random mating by using. With continued random mating, each generation will have the same distribution of genotype frequencies as the preceding one, with no change in allele frequency. Conditions that are necessary for a population to reach hwe in a single generation. Might introduce new versions of genes--new alleles-- or cause one allele to convert to a different, preexisting allele.
