Summary: This week in class we learned about X and Y linked traits. The X and Y genes are the sex genes that determine whether we are a boy or if we are a girl. X and Y linked traits are shown through subscript when reading them out. Usually males are more likely to get recessive traits rather than females because they only need one of the traits. FUN FACT: If a dad carries a trait on his Y gene then only his sons can get the trait.

SP2: Developing and using models
We developed models by finding the traits and where to put each of the traits that we found We used the models to figure out what the percentage would be that the off spring will have that certain trait. FUN FACT: These models are called punnet squares.
