Question

Quizplus · Accepted Answer

Epigenesis refers to changes in gene expression that occur as a result of environmental factors. Although monozygotic twins share the same genetic material, differences in their environments can lead to differences in gene expression over time, resulting in increased differences between the twins as they age. Thus, option B is the best choice. Options A, C, and D are incorrect as they do not accurately describe the impact of epigenesis on monozygotic twins.
