The measure of the variability of behavioral traits among individuals that can be accounted for by genetic factors is called:

B)monozygocity.
C)dianetics.
D)epigenetics.

Question

Quizplus · Accepted Answer

Heritability refers to the proportion of variability in a trait that can be explained by genetic factors. It is often expressed as a percentage between 0 and 1, with higher values indicating that genetics play a greater role in determining individual differences in the trait. Monozygocity refers to the fact that some individuals are identical twins, who share all of their genetic material. Dianetics is a pseudoscientific set of ideas developed by L. Ron Hubbard, and has no relevance to the study of genetics. Epigenetics refers to changes in gene expression that occur without changes to the underlying DNA sequence, and may be influenced by environmental factors. While epigenetic factors can play a role in behavior, heritability specifically refers to the proportion of variability that can be accounted for by genetic factors.
