Question 16 POST_UTME_VERITAS_UNIVERSITY • 2020 • BIOLOGY • objective

The process of genetic drift in a small population of finches on a remote island can lead to the fixation of a particular allele. However, if the population size increases, the effect of genetic drift decreases. Explain why this is the case.

Answer Options

A. Genetic drift is more pronounced in small populations due to the random sampling of alleles.
Correct Answer B. The increased population size allows for more genetic variation, reducing the effect of genetic drift.
C. Genetic drift is influenced by the mutation rate, which increases with population size.
D. The fixation of a particular allele is more likely in small populations due to the Wahlund effect.
Correct Answer
B
Correct Option:
The increased population size allows for more genetic variation, reducing the effect of genetic drift.
