Imagine that behavioural geneticists have found a way to measure the characteristic of "punctuality." The correlation between twin pairs is .75 for identical twins and .30 for fraternal twins.Based on this information,what would a behavioural geneticist conclude about the influence of genes and environment on this trait?
A) It is strongly influenced by the environment because the heritability coefficient is nearly 1.00.
B) It is strongly influenced by genetics because the heritability coefficient is nearly 1.00.
C) It is mildly influenced by genetics because the heritability coefficient is nearly 0.45.
D) It is mildly influenced by the environment because the heritability coefficient is nearly 0.45.
