Bottlenecks increases the affect of which of the following?
Correct answer: C. Genetic dirift
- A. Genetic linkage
- B. Genetic expression
- C. Genetic dirift
- D. Gene pool
Explanation
Genetic drift is a random change in the frequency of alleles in a population. It is caused by chance events, such as which individuals survive to reproduce. Bottlenecks can cause genetic drift to have a greater impact on a population because they reduce the population size and the number of alleles available in the population.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
