The hardy-weinberg principle is that genetic frequencies in a population? will remain stable from generation to generation will always be changing will not be affected by environmental changes are always in a 3: 1 ratio

Genetic orders can result when sister chromatids fail to separate properly during which phase is this problem most likely to occur
