Heritability is defined as:
A) an interdisciplinary field of study concerned with the genetic bases of individual differences in behaviour and personality.
B) a process in which individuals with genetically influenced traits that are adaptive in a particular environment tend to survive and reproduce.
C) a statistical estimate of the proportion of the total variance in some trait that is attributable to genetic differences among individuals within a group.
D) a statistical estimate of the proportion of the total variance in some trait that is attributable to environment.

Question

Quizplus · Accepted Answer

Heritability refers to the proportion of variance in a trait that is attributable to genetic factors. It is a statistical estimate and is typically expressed as a percentage ranging from 0% to 100%. This means that heritability estimates provide an indication of how much of the variability in a trait is due to genetic differences among individuals within a population, as opposed to environmental factors. Option A describes behavioral genetics, option B describes natural selection, and option D is a vague and inaccurate definition of heritability.
