Question

your mothers side of the family has a history of alcohol misuse. you acquire some of the genes for the disease, but you grow up in a home and community where alcohol use is generally absent. as a result, you never end up even being interested in alcohol. this demonstrates the concept of

o mutation.
o cohort effects.
o epigenetics.
o longitudinality.

Explanation:

Epigenetics studies how environmental factors affect gene expression. Here, genetic predisposition (genes for alcohol misuse) is present, but the environment (home/community with no alcohol use) influences gene expression (no interest in alcohol). Mutation is a change in DNA sequence. Cohort effects relate to group - specific experiences. Longitudinality is about long - term study.

Answer:

epigenetics.
