Question

which of the following experiments would provide the best data for determining the effect of environment? comparing identical twins raised in different environments with fraternal twins raised in different environments comparing fraternal twins raised in the same environment with identical twins raised in different environments comparing identical twins raised in the same environment with identical twins raised in different environments comparing identical twins raised in the same environment with fraternal twins raised in the same environment

Explanation:

Identical twins have the same genetic makeup. By comparing identical twins raised in the same environment to those raised in different environments, the effect of the environment can be isolated as genetics are constant. In other comparisons, either the genetic similarity is not maximized or the environmental variable is not the main focus.

Answer:

comparing identical twins raised in the same environment with identical twins raised in different environments
