A hypothetical population of blue jays has a gene that determines \"impulsivity.

Question

A hypothetical population of blue jays has a gene that determines "impulsivity." Jays with at least one dominant allele exhibit impulsive foraging decisions, such as foraging in the middle of a busy interstate highway, whereas jays that are homozygous for the recessive allele exhibit more timid foraging strategies, i.e., stay out of the middle of the road. If we follow this jay population for 50 generations into the future, which of the following will we most likely observe with respect to the "impulsive" gene in this population? O There will be no change in the frequency of the impulsive alele in this population because the foraging behavior gene is in Hardy-Weinberg equilibrium The impulsive allele will become fixed (100%) and all jays will forage impulsively. O The impulsive allele will be lost in the population and all Jays will be timid foragers. O The impulsive allele will have increased in frequency, but not to complete fixation (100%), because timid foragers survive longer.

Explanation / Answer

The impulsive allele causes aggressive foraging behaviour, like foraging in the mid of highway. Now, highways involve lots of fast moving vehicles which will harm those foraging on the highway. So, individuals with aggressive allele will gradually be lost and all jays will become timid foragers.

Thus correct choice should be

(C) The impulsive allele will be lost in the population and all jays will be timid foragers.
