Question

In a large population of randomly breeding foxes, a dominant allele results in a soft, brown pelt, while a recessive allele results in a rough, grey pelt. The dominant allele is found in 80% of the population while the recessive allele is found in 20%. There is no migration, drift, or selection in the population. When human beings enter this habitat, they selectively hunt foxes with brown pelts. After many generations of this activity, how will this population change? Please choose the correct answer from the following choices, and then select the submit answer button.

Answer 1

Answer:

The frequency of the recessive allele which codes for grey pelt character will rise above 20%, while the that of the dominant allele that confers brown pelt character will decrease below 80%.

Explanation:

Since the population of foxes with brown pelts are being selectively hunted by humans, the population of foxes with brown pelts will keep reducing while the population of foxes with grey pelt will thrive in its place.

Hence, the the frequency of the recessive allele which confers grey pelt attribute will rise above original 20% within the population, while the dominant allele will decrease below 80%.
