Question

Quizplus · Accepted Answer

The heritability of a trait can change because of changes in the environment. This means that the impact of genes on a trait can vary depending on the environmental factors that contribute to it. For example, if a certain trait is influenced by a gene that triggers a response to a specific environmental stimulus, changes in that stimulus could cause the heritability of the trait to be affected. While genes can mutate, this typically does not change the heritability of a trait unless the mutation affects the way the gene is passed down to offspring. It is not possible for a person to consciously change their heritability, as this is determined by genetic and environmental factors that are beyond an individual's direct control. The number of children in a family does not affect the heritability of a trait, as this is determined by the genetic and environmental factors that influence the trait, not by the number of children in a family.
