How do you predict the conditions and characteristics of your child? Well, in this essay I will explain the whole process to you. I will be using the sex-linked traits process. I will also be using X and Y chromosomes. Lets say there is a Mother and Father. The mother has green eyes (X) and the Father has green or blue eyes (X). If they have a daughter, than what color eyes will she have? Well, she will have green eyes (XX) because the green eyes from the parents is dominant over the blue eyes. Same thing with every other thing. Only males can have Y chromosomes. So if a father has a Y chromosome, and a mother has blue eyes (X) than if they have a son, the son will have blue eyes (XY). This process is extremely easy if you know it. as I said, this applies to everything else like colorblindness, skin color, etc.
