A Quantitative Geneticist Measures the Broad-Sense Heritability for Bill Length

Multiple Choice

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.
