Question

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

Explanation:

Identical twins have the same genetic makeup. By comparing identical twins raised in the same environment with identical twins raised in different environments, the variable of environment is isolated while keeping genetics constant. This allows for the assessment of how environment affects traits, and by extension, the role of genetics in determining traits when environment varies.

Answer:

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