A heritability estimate is
A) an estimate of the proportion of a trait that is attributable to genetics.
B) an estimate of the proportion of between-subject variability occurring in a particular trait in a particular study that resulted from genetic differences among the subjects of that study.
C) likely to be higher in studies with little environmental variation.
D) both A and C
E) both B and C

B) confound the experiment.
C) increase the accuracy of the heritability estimate.
