The heritability score for athletic ability estimates the: relative contributions of genetic and environmental factors in the development of an individual's athletic ability. amount of variation in athletic ability in an entire population that is due to differences in their genes. level of genetic influence on an individual's athletic ability. extent of influence of evolution on a population's athletic ability.

amount of variation in athletic ability in an entire population that is due to differences in their genes.

Explanation:

Heritability score is a number that indicates the proportion of a trait that is genetic. Inheritance is the ratio of genetic variation to the total variation of a given attribute in a population. Variation of a trait in the population is referred to as phenotypic variation, while genetic variation in a population is referred to as genotypic variation. Thus, heritability is a ratio of genotypic variation to phenotypic variation. Based on this, we can state that the heritability score for athletic ability estimates the amount of variation in athletic ability in an entire population due to differences in their genes.
