Crank

To answer this we need to analyze each statement

camouflage, mimicry, and stingers: This is meant to escape predation and fend off predators, so this is the correct answer.

hibernation and migration: This is meant for breeding and or food energy storage, to pass hard seasons so is also incorrect.

courtship and breeding behaviors: This is meant for reproduction and to ensure offspring so this is incorrect.

nesting and food gathering: this is a behavior for survival, resource use rather than defense, si this is not correct.

Answer:

75% brown, 25% white

Explanation:

This question involves a single gene coding for color in chickens. The allele for brown color (B) is dominant over the allele for white color (b).

According to this question, a brown rooter with genotype 'BB' was crossed with a white hen (bb). The offsprings in the F1 generation will all possess the 'Bb' genotype and be brown colored. However, if these F1 offsprings are self-mated i.e Bb × Bb, the proportion of F2 offsprings will be 1BB, 2Bb, 1bb.

Since BB, Bb and Bb offsprings are Brown in color and bb is white in color, this means that the expected phenotypic appearance of the F2 offsprings will be:

¾ or 75% brown and ¼ or 25% white
