William is a researcher who studies the pattern of gene expression in human beings.He observes that when people face major life-changing events or stressors,they experience depression that ranges from mild to severe.If people have a good support system,the expression of the gene related to depression is mitigated.William most likely studies _____ in this scenario.

Question

Quizplus · Accepted Answer

William's focus on how environmental factors (life-changing events or stressors) can influence the expression of the depression-related gene suggests that he is studying epigenetics. Epigenetics is the study of how genes can be turned on or off by environmental factors without changing the underlying DNA sequence. The role of a good support system in mitigating the expression of the depression-related gene further supports the idea that epigenetic factors are at play, as social support is a well-established environmental factor that can impact gene expression. Genealogy (A), metagenomics (C), and preformationism (D) are not directly relevant to this scenario.
