Quizplus · Accepted Answer

The fact that identical twins who have separate placentas are somewhat less similar than identical twins who share a placenta suggests that there are prenatal environmental factors at play that can influence development, such as nutrient levels, exposure to toxins or infections, and other aspects of the maternal environment. This highlights the importance of both genetic and environmental influences on human development.
