A population has a low V_G and high V_E. Which of the following statements are true for this population? A) The population has high heritability. B) The population has low heritability. C) The population has average heritability. D) Heritability is not affected by V_G and V_E.

Question

Quizplus · Accepted Answer

Heritability in a population is calculated as the ratio of genetic variance (V_G) to the total phenotypic variance, which includes both genetic variance and environmental variance (V_E). A low genetic variance (V_G) relative to a high environmental variance (V_E) results in low heritability, indicating that the environment has a greater influence on the phenotypic variation than genetics.
