The claim that different traits are influenced by genetic inheritance to varying degrees and environmental factors can influence biological factors via regulation of gene expression represents which concept?

• A. Theory of Evolution
• B. Natural Selection
• C. Criticisms of Genetics
• D. Epigenetics

Answer: (C)

Epigenetics is the idea here: the environment can influence how strongly or weakly genes are expressed without changing the DNA sequence itself. This means that traits, while rooted in genetic inheritance, can be shaped by environmental factors through mechanisms that turn genes on or off or adjust their level of activity. That regulatory process explains how biological factors can be influenced by surroundings, producing different phenotypes. The other options describe evolutionary processes or broad debates about genetics, which don’t capture the mechanism of environment-driven gene regulation.
