Question

Quizplus · Accepted Answer

The heritability of a trait is the proportion of variation in a population that is caused by genetic variance. It ranges from 0 (no genetic contribution) to 1 (complete genetic contribution), and is an important concept in understanding the genetic basis of traits and diseases. Options A, B, D, and E do not accurately describe the definition of heritability.
