A quantitative geneticist measures the broad-sense heritability for bill length in an isolated population of ducks to be 0.75.This result suggests that:
A)the population tested has a high variance in bill length.
B)in the population tested,75% of the variance in bill length is due to genetic differences among individuals.
C)in the population tested,75% of the variance in bill length is due to environmental differences among the individuals' microhabitats.
D)if all the ducks in the population tested were raised in identical environments,75% of them would have identical bill length.
E)in the population tested,75% of the ducks have a bill length that is within one standard deviation of the mean.

Broad-sense heritability measures the proportion of phenotypic variation that is due to genetic variation among individuals in a population. A heritability of 0.75 means that 75% of the variation in bill length in the population tested is due to genetic differences among individuals.
