Zac and nina are studying for a psychology test. zac states that heritability refers to the extent to which genes are responsible for an individual's level of a particular characteristic is genetic. nina disagrees, stating that heritability refers to the extent to which genes are responsible for variation among individuals in a particular characteristic. which student is correct

Nina is correct, because, according to the definition of heritability, "Heritability is a statistic used in the fields of breeding and genetics that estimates the degree of variation in a phenotypic trait in a population that is due to genetic variation between individuals in that population." Therefore heritability refers to the variation within a population, so Nina is correct.

Nina has the correct answer. Heritability is actually the extent to which the genes are responsible for the variation among individuals in a particular characteristic. Specifically, it is a figure that determines the rate of variation in a single phenotypic trait in a population with regard to the genetic variation.
