Question

Quizplus · Accepted Answer

The adoption of both Abigail and Cassandra from different biological parents suggests that genetic influences on their levels of guilt may differ. As they get older, the evidence for genetic influences is likely to get weaker because they don't share the same genes. On the other hand, they were both raised in the same shared environment with the Gianellis, so the evidence for the influence of a shared environment on guilt may get stronger. Therefore, the best answer is C: weaker genetic influences on guilt and stronger shared environmental influences on guilt.
