In humans, having freckles is the result of a dominant gene, and not having freckles is a recessive trait. If a freckled man who is homozygous for this trait has a child with a woman who does not have freckles, which of the following best describes how their child would most likely appear?
A. Their child would not have freckles if the father passes on the recessive allele.
B. Their child would have freckles.
C. Their child would not have freckles.

im thinking it would be a or d maybe because the traits are never certain...right?

Late response, but:

Foe this trait, non freckled is dominant and freckles is recessive (I’ll call the dominant allele F and the recessive allele f)

The man is freckled and homozygous —> FF

The woman has no freckles — ff

The child can only get 1 allele from each parent. In this case, the dad passes on F and the mom passes on f. So the child will always be Ff and thus have no freckles.

Wait hold on sorry

Vocaloid · Answer

Sorry, I messed up - freckles is dominant

Dad is freckled - FF
Mom has no freckles - ff

So children will be Ff and thus *always* have freckles
