The idea that genes express themselves within an environment is a central component of:
A)degree of relatedness.
B)epigenetics.
C)heritability.
D)phylogeny.

Question

Quizplus · Accepted Answer

The idea that genes express themselves within an environment is a main concept of epigenetics. Genetics alone cannot account for all variations in traits and behaviours, but epigenetics can explain how environmental factors can cause changes in gene expression. Choice A is incorrect since degree of relatedness refers to the proportion of shared genes between individuals in a population. Choice C is incorrect because heritability refers to the proportion of variation in a trait that is due to genetic factors. Choice D is incorrect because phylogeny refers to the evolutionary history and relatedness of species.
