Question 5

The correlations for IQ increase as the similarity in genotype rises.

Accepted Answer

Question 6

The concept of range of reaction reflects only what we currently know about the way genotypes are expressed in environments already familiar to us.

Accepted Answer

The range of reaction is the idea that a genotype can give rise to a range of possible phenotypes depending on the environment in which it develops. However, this concept is limited by our current knowledge of the specific genotype and environment interactions that have been studied. Future research may reveal new aspects of this relationship that expand our understanding of the range of reaction.
