Question

Use the Natural Selection interactive, select the light brown background, and advance the interactive until the end of the trial. Considering the inheritance of color in these beetles, could the population of beetles ever be composed of only light brown beetles? The entire population of beetles could be light brown because directional selection will occur and one allele will be favored over the other. The entire population of beetles could be light brown because their increased fitness In the O light brown environment will eventually result in the elimination of light gray and dark brown phenotypes The entire population of beetles could not be light brown because underdominance will result in the same allelic frequency. The entire population of beetles could not be light brown because the beetles with a light brown phenotype are heterozygotes.

Answer 1

Answer:

The entire population of beetles could not be light brown because the beetles with a light brown phenotype are heterozygotes

Explanation:

The figure is attached which indicates that allelic frequencies of both B and b alleles are nearly identical as pie chart also illustrate that the equal area of grey and dark. Thus, more than these two are enclosed by light brown. Light brown trait seem to be controlled by Bb genotype because of which heterozygotic light brown beetle will produced.
