A sharp lowering of a populations gene pool because of an environmental, or human-caused, change. How does it effect populations? It decreases genetic variation and makes the population more susceptible to disease. Genetic variation is good. True or False? True. What kind of populations are susceptible? conutスコア 計算式WebPopulation bottlenecks occur when a population’s size is reduced for at least one generation. Because genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population’s genetic variation by a lot, even if the bottleneck doesn’t last for very many generations. conutスコア 栄養評価 問題点
