Quizplus · Accepted Answer

Heritability refers to the extent to which differences in traits between individuals in a population can be attributed to genetic differences. It is usually expressed as a statistic between 0 and 1, with higher values indicating a greater genetic contribution to the variation in the trait. It does not refer to the amount of a trait that is determined solely by genetics in an individual, as environmental factors can also play a role in how genes are expressed.

Answer: D
 While the likelihood of a parent passing on a particular trait to their offspring is influenced by genetics, this is not a comprehensive definition of heritability. Heritability is concerned with the proportion of variation in a trait that is due to genetic variation, rather than specific predictions about the transmission of traits from one generation to the next.
