C)if heritability for a trait is high in a particular population, improving the environment is unlikely to result in a significant improvement in the trait over time.

E)heritability says nothing about the nature of differences between populations in a characteristic.

Question

Quizplus · Accepted Answer

Heritability refers to the proportion of variation in a trait that can be attributed to genetic differences among individuals in a population. A high heritability does not mean that the environment cannot improve the trait; it simply indicates that a large portion of the variation in the trait within the population is due to genetic differences. Environmental improvements can still significantly impact the trait, even if its heritability is high.
