Biology Question

Post by cornears » Thu Nov 19, 2009 4:57 pm

Lactose intolerance is inherited as an autosomal dominant trait. If a lactose intolerant individual knows that he is heterozygous (because only one of his parents was lactose intolerant) and he plans to father a child with a normal woman, what are the chances that their child will be lactose intolerant?

I think, canalon is right, cornears knows genotypes of both parents, so what's the problem? :roll:

Cis or trans? That's what matters.
