which of the following is an approach to researching gene - environment interactions?
a severing the corpus callosum
b examining cognition over time
c surgical removal of brain areas
d examining phenotypes and genotypes within epigenetics

Explanation:

Epigenetics studies how environmental factors can affect gene - expression without changing the DNA sequence. Examining phenotypes and genotypes within epigenetics helps in researching gene - environment interactions. Severing the corpus callosum and surgical removal of brain areas are related to brain function research, not gene - environment interactions. Examining cognition over time is more related to cognitive development and not directly to gene - environment interactions.

Answer:

D. examining phenotypes and genotypes within epigenetics
