If a specific trait were found 7.5 percent of the time in both members of sets of monozygotic twins and 8.3 percent of the time in both members of sets of dizygotic twins,we would conclude:

B)the environment was not involved at all in its expression
C)the environment was the only factor involved in its expression
D)inheritance was a relatively unimportant factor
