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. Create a Punnett square to show

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,
3 Points
etc…)
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.
