A)Gene count
B)Evolution
C)Heritability
D)Inheritance

Question

Quizplus · Accepted Answer

Heritability is a statistical measure that estimates the degree of variation in a trait (such as intelligence) within a population that can be attributed to genetic factors. Therefore, heritability is the fraction of the variance in a trait that is due to genetics. Gene count (A) refers to the total number of genes in an individual's genome, while evolution (B) refers to the process of change in species over time due to natural selection, genetic drift, and other factors. Inheritance (D) refers to the passing of genetic traits from parent to offspring. While all of these concepts are related to genetics, heritability specifically refers to the proportion of variance in a trait that is due to genetic factors.
