Speaking Parseltongue is a rare feature in the Wizarding world. Only descendents from Slytherin might have this ability.Harry speaks Parseltongue, but Ginny doesn’t and neither did Harry’s parents.
Suggest if the allele for speaking Parseltongue is dominant or recessive:
What are the chances that Harry’s and Ginny’s children speak Parseltongue if (a) Ginny isn’t a carrier and (b) if Ginny does carry the allele?
Harry+ GinnyHarry
+ Ginny
(a) (b)
![Page 22: Lesson Sequence 1. 2. 3. 4. Genetic Crosses 5. 6. 7. 8. 9. 10.](https://reader033.fdocuments.us/reader033/viewer/2022051401/5697c00f1a28abf838cca3a4/html5/thumbnails/22.jpg)
(c) Actually, Harry didn’t inherit the two recessive Parseltongue alleles, but they were transferred to his DNA when Voldemort tried to kill him.
What is the scientific name for this process?
Harry +Voldemort
Harry +Voldemort

(a) Being werewolf (W) is dominant over not being a werewolf (w). Remus Lupin is a werewolf (Ww), but his wife , Nymphadora Tonks, is not.
What are the chances that their son is a werewolf?

(b) Both Remus and Nymphadora also carry the allele for speaking Parseltongue. What are the chances that their son is a werewolf
who speaks Parseltongue?
