It's not about which parent has "stronger" genes, but rather how genes from both parents interact and contribute to a child's traits.
While each parent contributes half of their genetic material, the expression of these genes can be influenced by various factors. For example, some genes are dominant, meaning they are more likely to be expressed, while others are recessive and may only be expressed if inherited from both parents.
Additionally, environmental factors like nutrition, lifestyle, and even the child's own random genetic mutations can play a role in how genes are expressed.
It's important to remember that genes are complex and don't operate in a simple "stronger vs. weaker" manner. Instead, they work together in a dynamic and intricate interplay to shape an individual's characteristics.
Therefore, it's more accurate to say that both parents contribute equally to their child's genetic makeup, and the combination of their genes, along with environmental influences, determines the child's unique traits.
