question 14
what was the primary finding of the minnesota study of twins reared apart?
a identical twins, whether raised together or apart, have very similar personalities.
b twins of any kind have very similar personalities, regardless of where they are raised.
c identical twins have very similar personality when raised together, but not when raised apart.
d fraternal twins have very similar personalities whether raised together or apart.

Explanation:

The Minnesota Study of Twins Reared Apart focused on identical twins (monozygotic) who were raised in different environments. The key finding was that identical twins, even when raised apart (or together), showed very similar personalities, highlighting the strong genetic influence on personality. Option B is incorrect as it generalizes to "twins of any kind" (fraternal twins were not the focus and don't show the same similarity). Option C is wrong because the study showed identical twins had similar personalities even when raised apart. Option D is incorrect as fraternal twins (dizygotic) do not have the same level of personality similarity as identical twins, regardless of rearing environment. So the correct answer is A.

Answer:

A. Identical twins, whether raised together or apart, have very similar personalities.
