two dwarfs with achondroplasia decide to have children. What is the likelihood that their 1st living child will be normal height? 

I think it would be 1/3 because 

    D    d

D| DD  Dd

d| Dd    dd

if their genotypes are (dd) then it would be lethal so I didnt include them

Achondroplasia is an autosomal dominant disorder. The lethal genotype is DD, and dd is a normal genotype. So, if we do not include DD genotype, then the likelihood that their 1st living child will be normal height is really 1/3.
