Question

Genetic drift provides diversity in the population”. Do you agree? Justify the statement.​

Answer 1

Answer:

Genetic drift decreases genetic diversity within a population. It is a change in allele frequencies due entirely to random chance and is more likely to affect smaller populations than large ones....

Answer 2

Ans) Genetic drift decreases genetic diversity within a population or it may also result in the loss of few rare alleles in the population.

• It may give rise to new population which id distinct from original or parental population and thus genetic drift is a mechanism of evolution.
• It is a change in allele frequencies due to random chance and the smaller population affects more than the larger one .
• Genetic drift can be defined as the  change in the frequency of an existing gene variant in a population due to sampling error / random sampling of organisms.
