An estimate of the proportion of trait variability in a population that is determined by variations in genetic inheritance is termed
A) genetic range.
B) inheritability.
C) heritability.
D) reaction range.

Question

Quizplus · Accepted Answer

Heritability is the correct term for describing the proportion of trait variability in a population that is determined by variations in genetic inheritance. Genetic range refers to the range of genetic variation present in a population, inheritability is not a commonly used term in genetics, and reaction range refers to the range of potential expression of a trait due to environmental influences. Therefore, the best answer is C) heritability.
