Identical twin raccoons are raised in different environments and yet behave very differently.This is an example of
A)heterozygous alleles.
B)the norm of reaction.
C)genetic differentiation.
D)acclimation.

Question

Quizplus · Accepted Answer

The fact that the identical twin raccoons behave differently despite being genetically identical suggests that their behavior is influenced by environmental factors. The concept that the same genotype can result in different phenotypes in different environments is known as the norm of reaction. Therefore, B is the correct choice. A is incorrect because heterozygous alleles refer to having different alleles at a given gene locus, which is not the case with the identical twins. C is incorrect because genetic differentiation refers to the divergence of allele frequencies in different populations, which is also not relevant to this example. D is incorrect because acclimation refers to an individual's short-term physiological adjustments to environmental changes, which is also not the case with the twin raccoons.
