Question

1. does a large population that migrates to another location experience genetic drift? explain. 2. how does migration affect a populations gene pool?

Explanation:

1. Genetic drift is more pronounced in small populations. In a large - migrating population, random changes in allele frequencies due to chance (which is genetic drift) are less likely to occur as the large size buffers against random events.
2. Migration can introduce new alleles into a population's gene pool (gene - flow). It can also change the frequency of existing alleles. If migrants have different allele frequencies compared to the recipient population, the gene pool of the recipient population will be altered.

Answer:

1. A large population that migrates is less likely to experience significant genetic drift because the large size of the population reduces the impact of random sampling of alleles.
2. Migration can increase the genetic diversity of a population's gene pool by introducing new alleles and can change the frequencies of existing alleles in the gene pool.
