A) The IQ scores of identical twins raised separately are more similar than those of fraternal twins raised together.

Explanation:

Role of heredity in determining intelligence: In psychology, several research has been one of the relation between heredity and environment in determining the intelligence of an individual. Researchers have identified that twins' studies were the most successful in identifying the IQ scores as they share the same genetic material.

According to the researcher, genetics plays a more important role as compared to the environmental factors and therefore in determining intelligence genetics play 60% of the role whereas 40% is the environmental factors.

Answer from: missbecca1229p6glel

The correct statement regarding the role of heredity in determining the intellect is that the IQ scores of twins raised separately are more similar than those of fraternal twins. So, the correct option is A.

The IQ scores of twins are determined by their genetics more than the environments they are raised under or the way of their upbringings for a period.

IQ of twins.The IQ score of an individual depends on more than half of the genetics' information, and a very less significant part is played by the environment or upbringing of such individual.It was found in research that the IQ scores of separately raised kids are still identical due to hereditary characteristics shared by them, irrelevant of their upbringing environments being different.

Hence, the correct option is A that the IQ scores of identical twins are more similar to that of the fraternal twins.
