Bottlenecks and Founder Effects. Genetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a populations size is reduced for at least one generation.ottlenecks and Founder Effects. Genetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a populations size is reduced for at least one generation.
Genetic drift is more pronounced in small populations than in large ones Chance deviations from expected results (which cause genetic drift) occur whenever organisms engage in sexual reproduction Genetic drift usually leads to the loss of alleles and reduced genetic variability Population bottleneck: an evolutionary event that occurs when a stressful factor reduces population size greatly and eliminates some alleles from a population o Ex. disease, starvation, drought Founder effect: an ...
