Question

the study of the interplay of genes and multiple levels of the environment, which leads to “molding” of heredity and environmental influences, is called
a. twin studies
b. molecular genetics
c. epigenetics
d. phenotyping

Explanation:

Epigenetics studies how environmental factors can affect gene expression without changing the DNA sequence, thus 'molding' heredity and environmental influences. Twin studies focus on comparing twins to understand genetic and environmental contributions. Molecular genetics is about the molecular - level study of genes. Phenotyping is about determining phenotypes.

Answer:

C. epigenetics
