In the field of genetics, traits can become very confusing, especially when using yourself as an example. Just take a look in a mirror, and you might figure out that you may have several traits from both sides of your parents. Some traits may even come from generations past, and even before that time. Depicting the different types of traits had confused many individuals, so they finally continued to make a drawing other wise known as the Punnett square. Then main function of a Punnett square, is to find the possibility of a particular trait. Whether the trait is; hair color, eye color, body color, eyelashes, nose shape, finger shape, height, etc, you can always figure it out. The Punnett square is a plain square with two lines going to the opposite side. On the outer ends of the square you put in your parents genotype, whether its Tt, tt, or TT.
The genotype, and phenotype of a person are two completely different thing. The phenotype of a person is their physical appearance, while the genotype tells if their homozygous, heterozygous, dominant, recessive, etc. Once you fill out the outer side of the Punnett square, you can begin to write your information in the square as well. IF the outer side has TT, and tt, all the outcomes in the square would be Tt. Once you figure out the probability, you can also find the percentage as well.
