Question

Ian and Nolan are identical twins who were adopted into different families shortly after birth. Use what you know about the stability of intelligence over time and the relative contributions of genetic and environmental factors to predict how similar Ian and Nolan's IQ scores will be at age 5 and age at 25.

Answer 1

Answer and explanation:

Ian and Nolan have a tendency to reach similar scores at age 5 since twin studies show that shared genetics of identical twins cause them (the twins) to have incredibly IQ percentages. This same thing applies for when they get older, around age 25, because IQ scores don't really change a lot throughout a lifetime.
