a    Aa   aa

a    Aa   aa

Aa have the condition

aa are normal/healthy

Answer 3

I can only figure this out by typing it through.

Parent A has autosomal dominant condition A and is heterozygous.  Therefore they are Aa.

Parent B is homozygous recessive, so is aa.

Aa                                  aa

Kids will be:

Aa

Aa

aa

aa

d)half their children will have the condition.
