Bottleneck and founder effects are situations that make what condition more likely to affect allele frequencies in a population?
A) nonrandom mating
B) natural selection
C) genetic drift
D) mutation
Bottleneck Effects
A phenomenon where a population's size is significantly reduced for at least one generation, leading to a loss of genetic diversity.
Founder Effects
A genetic phenomenon that occurs when a new population is established by a very small number of individuals from a larger population, leading to a reduction in genetic variation and a potentially different genetic structure compared to the original population.
Allele Frequencies
The proportion or prevalence of different alleles (versions of a gene) in a particular population, which can change over time due to evolutionary pressures.

Final Answer :
C
Explanation :
Bottleneck and founder effects are both scenarios that lead to genetic drift, a mechanism of evolution where allele frequencies in a population change due to random events rather than natural selection, mutation, or nonrandom mating. These effects reduce genetic variation and can significantly alter allele frequencies unpredictably.
