The extent to which the variability of a trait among groups is genetically influenced is referred to as

B)among-group heritability.
C)cross-group heritability.
D)within-group heritability.

Question

Quizplus · Accepted Answer

Between-group heritability is the extent to which the differences in a trait between two or more groups are due to genetic factors. This concept is used to assess if genetic differences contribute to observed variations between different groups (e.g., ethnic groups, populations) in certain traits. Choice B ("among-group heritability") is not a valid term in genetics. Choices C and D ("cross-group heritability" and "within-group heritability") are not commonly used terms in this context.
