Question

a) They both inherited personality traits from their parents.
b) They shared the same living environments during childhood.
c) They were raised in the same way by their parents.
d) All of these are correct.

Answer 1

Erika and Mitzi might have similar personality traits due to a combination of inherited traits from their parents, shared living environments, and a similar upbringing.

Step-by-step explanation:

The reason why Erika and Mitzi, sisters born 3 years apart, might have personality traits that are quite similar is because of all of the above options (d) - they both inherited personality traits from their parents, shared the same living environments during childhood, and were raised in the same way by their parents. Research in the field of behavioral genetics, such as the Minnesota Study of Twins Reared Apart, has shown that some aspects of our personalities are largely controlled by genetics. Identical twins, whether raised together or apart, have been found to have very similar personalities, suggesting a heritability of some personality traits.
