The extent to which a trait is inherited versus acquired through interactions with the environment defines the concept of: Select one: a. heritability b. genetic predisposition c. genetic engineering d. concordance

The correct answer is a. heritability.<br /><br />Heritability refers to the extent to which a trait is inherited versus acquired through interactions with the environment. It is a statistical concept used to measure the proportion of variation in a trait that can be attributed to genetic factors, as opposed to environmental factors.<br /><br />Genetic predisposition (option b) refers to the likelihood of an individual developing a particular trait or disorder based on their genetic makeup. Genetic engineering (option c) is the process of manipulating an organism's genetic material to achieve desired traits or outcomes. Concordance (option d) refers to the presence of the same trait in both members of a pair of twins or other close relatives.<br /><br />Therefore, the correct answer is a. heritability.
