Several studies of long-separated identical twins have found that these twins

A) have little in common because of the different environments in which they were raised.
B) have many similarities,in everything from medical histories to personalities.
C) have similar personalities,but very different likes,dislikes,and life-styles.
D) are no more similar than are fraternal twins reared apart.

Studies of long-separated identical twins have consistently found that they have many similarities, including medical histories and personalities. This is because identical twins share the same genetic material, which can influence their development and behavior. While environmental factors can also play a role, the similarities observed in these studies suggest that genetics may be the primary factor shaping their similarities.
