Final answer:
A human mother's genes influence brain development, while a human father's genes influence growth.
Step-by-step explanation:
Research has shown that a human mother's genes tend to influence brain development, while a human father's genes tend to influence growth. This implies that the mother's genes play a role in shaping the development of the brain, while the father's genes contribute to physical growth. It is important to note that both parents' genes can have an impact on various aspects of development, but there are specific tendencies based on gender.
