Question

If heredity is REALLY important, then

a. fraternal twins should be more similar than identical twins if they have been raised apart.
b. identical twins raised apart should be nearly as similar as identical twins raised together.
c. fraternal twins raised apart should be more similar than identical twins raised together.
d. there should be no differences between identical twins and fraternal twins raised together.

Answer 1

Correct choice is (B)! This aligns with the notion that heredity plays a crucial role in determining similarities between individuals, and even when raised apart, identical twins would still exhibit strong similarities due to their shared genetic makeup.

Answer 2

b) Identical twins raised apart should be nearly as similar as identical twins raised together.

Step-by-step explanation:

In the field of behavioral genetics, the Minnesota Study of Twins Reared Apart found that identical twins, whether raised together or apart, have very similar personalities. This suggests that heredity plays a significant role in personality traits. Fraternal twins, on the other hand, are not genetically identical and therefore may have greater differences in personality. Therefore, option b is the correct statement: identical twins raised apart should be nearly as similar as identical twins raised together.
