Question

How would the presence of these new individuals affect genetic drift in the small population?

1) The addition of a few individuals would increase the mutation rate in the population, decreasing the effects of genetic drift.
2) The alleles contributed by the new individuals would spread rapidly through the gene pool, resulting in strong genetic drift.
3) The introduction of new individuals would increase the population size, increasing the effects of genetic drift.
4) The new individuals would likely increase genetic variation in the population, reducing the effects of genetic drift.

Answer 1

The presence of new individuals in a small population can have different effects on genetic drift.

Step-by-step explanation:

Genetic drift is the random change in allele frequencies in a population due to chance events. The presence of new individuals in a small population can have different effects on genetic drift:

1. The addition of a few individuals can increase the mutation rate, which can decrease the effects of genetic drift.
2. The alleles contributed by the new individuals can spread rapidly through the gene pool, resulting in strong genetic drift.
3. The introduction of new individuals can increase the population size, which can increase the effects of genetic drift.
4. The new individuals can likely increase genetic variation in the population, reducing the effects of genetic drift.

Overall, the effects of new individuals on genetic drift depend on various factors and can lead to either an increase or decrease in genetic drift.
