Question

In a population of owl monkeys, allele T (TT and Tt) codes for tufted tails. The frequency of allele t (tt), which codes for nontufted tails, is 40 percent. If a new predator starts catching the monkeys by their tufts and natural selection occurs, which of the following would most likely happen over time?

a) No changes would take place because the allele governing tufted tails is not dominant.
b) The frequency of allele T would decrease and the frequency of allele t would increase.
c) The frequencies for the two allele forms would equal out.
d) The frequency of allele T would increase.

Answer 1

The answer to this is B

Answer 2

Option B, The frequency of allele T would decrease and the frequency of allele t would increase.

Step-by-step explanation:

It is given that the predator catches monkeys on the basis of their tufts which means that the population of monkeys with tufts will decrease tremendously in the nearby future.

Thus, as the population of monkeys with tufts decreases, the allele for tufted tail will also decrease and hence there will less number of mating that shall produce a tufted monkey which in turn shall increase the frequency of "t" allele

Hence, Option B is correct
