Q4 Not the most likely!

Hmmm, possible but not the most likely answer.


Does it skip a generation? = yes

Is there an imbalance in whether males/females are affected? = yes, all male.

Note also, that the people marrying into the family are unaffected. You can’t know their genotype for sure, but when you look at it again, assume they aren’t carriers… [note that the most likely answer to the question doesn’t need this assumption].
