Typical prenatal development depends on which of the following?
A)The genome to code in the absence of environmental inputs
B)The genome to code and the environment to provide inputs
C)Properly timed gene expression without environmental inputs
D)Environmental inputs and deregulated genetic coding

Question

Quizplus · Accepted Answer

Prenatal development is influenced by both genetic and environmental factors. The genome provides the basic blueprint for development, but environmental inputs such as nutrition, stress, and exposure to toxins can have a significant impact on development. Therefore, option B is the best choice. Option A is incorrect because genetic coding alone cannot account for the complexities of prenatal development. Option C is incorrect because gene expression is influenced by both genetic and environmental factors. Option D is incorrect because deregulated genetic coding can lead to developmental disorders, but environmental inputs also play a role.
