Question

question 35
which of the following is an example of genetic drift?
o the bottleneck effect
o the founder effect
o the mutation effect
o both a and b

Explanation:

Genetic drift is a mechanism of evolution where allele frequencies in a population change over generations due to random sampling. The bottleneck effect occurs when a population's size is suddenly reduced, leading to a change in allele frequencies. The founder effect happens when a new population is established by a very small number of individuals from a larger population, also causing allele - frequency changes. Both are examples of genetic drift. Mutation is a different evolutionary mechanism involving changes in DNA sequence.

Answer:

D. both a and b
