He is very proud of this trait and wants to pass it on to his children, but he married a girl who is heterozygous for her black hair.

YES! Any with white hair would be purebred because they would have 2 of the same recessive allele. 3 Points

8. Neville Longbottom settled down a few years ago with a nice Muggle girl, Susie, and had a baby. No one in Susie’s family has ever had magical abilities, but Little Longbottom is showing signs of being a wizard! Susie is now convinced that there was a mix-up at the hospital. Create a Punnett square to help answer the questions below.

YES! Susie has only dominant genes, so her children would all be Muggle (except mutations, recessive genes passed down, etc…) 3 Points

9. Harry Potter is a parseltongue, which means that he can speak to snakes. No one in his family has ever had this ability, however. If you didn’t know where Harry’s ability came from, and assuming that there was no mistake at the hospital and Harry was not adopted, how could you GENETICALLY explain it? Be specific and use complete sentences

Any reasonable response will do having to do with either mutations or recessive genes passed on without showing in the older generations. 4 Points
