The heritability of a trait: (a) is the proportion of phenotypic variation in the population that is due to genetic differences between individuals (b) determines whether natural selection could result in evolutionary change (c) is the proportion of an individual's phenotype that is due to its genotype (d) a and b are correct (e) a, b, and c are all correct
