Why I think we need unproven dominant

somewhere around 16-17 eggs puts you right there.

I worked in a genetics lab. We had lethal recessive mutant genes and lethal codominant mutant genes. We had no lethal dominant genes.

Lethal recessive mutant (a), normal gene (A)
AA looks normal, lives
Aa looks normal, lives
aa dies

Lethal codominant mutant (A), normal gene (a)
AA dies
Aa does not look normal, lives
aa looks normal

Lethal dominant mutant (A), normal gene (a)
AA never produced
Aa dies
aa looks normal
