@borealssb1384 What are you talking about? There's not a 50/50 chance a gene from each parent will be carried over. There's a 100% chance a gene from each parent will be carried over. The point is that one of those genes will be dominant. There's not a 50/50 chance one gene will be dominant over the other. There's a 100% chance the darker gene (hair, eyes, skin) will be dominant, which is what the poster is obviously referring to. Not a literal "battle" maybe, buy one gene's trait is overpowering the other gene's trait. Even two evenly mixed skin tone, hair colour, or eye colour, parents, each with a dominant gene and a recessive gene, won't give a child a 50% chance at having lighter skin, hair, or eyes. It'd be a 25% chance of getting a recessive gene from both parents, a 50% chance of getting 1 dominant gene from either parent, and a 25% chance at getting 2 dominant genes from both ... 75% chance of a darker skin tone, hair colour, or eye colour. You'd need one parent with 2 recessive genes, and a parent who has a dominant gene as well as a recessive gene, to get you a 50% chance of getting 2 recessive genes.
