In a relatively small iguana population the allelic frequency is tracked for three generations. webbing is a recessive allele; no webbing is the dominant allele. during one very rainy spring and summer, a flood washes all the iguana without webbed feet out to sea. by the fall, and three generations later, you have the gene pool seen here. this is an example of a) gene flow. b) immigration. c) genetic drift. d) founder effect.

The answer is C

Explanation: The random change in the gene pool is due to genetic drift. Remember, genetic drift occurs at a more rapid rate when the population size is reduced. The flood is a random occurrence. It could have as easily been a drought.

C) genetic drift.

Explanation:

In this question, the alleles of the dominant trait that is without webbed feet are eliminated from the population due to flood in the area where the iguana population was living.

This elimination of the dominant alleles due to flood is a by chance event or a random event. This event changed the gene pool of the population and the population with left or recessive alleles will survive.

This change in the gene pool of a small population due to the random effect is known as the genetic drift.

Thus, Option-C is the correct answer.
