a) be 80 percent hereditary.
b) be 65 percent hereditary.
c) be less than 50 percent hereditary.
d) have no hereditary basis.

Answer 1

Answer:

• Option-(B): Because identical twins separated at birth did have the same prenatal environment and were often placed in homes that are socially and educationally similar, some researchers believe that intelligence would seem to be 65 percent hereditary.

Explanation:

• The factor of intelligence is greatly effected by the over all hereditary or genome of the both the parents and then if we suppose that the identical twins are separated at birth did have the same prenatal environment and were often placed in homes that are socially and educationally similar. As the total genes that each individual posses is greatly influenced on the over all personality of the person but the environment in which the different people are raised also plays a very vital role in the over all development of the twins as per this case.
