In humans, freckles (F) on the skin are dominant to no freckles (f). If two parents are heterozygous for the trait, which statement below best describes their chances of having a child with no freckles?

a

It would be extremely rare for the freckled parents to have a child without freckles because freckles are dominant.

b

The parents will most likely have three children with freckles before having a child without freckles.

c

Every time they reproduce, the parents have a one in four chance of having a child without freckles.

d

If the parents already have three children with freckles, then they are more likely to have a child without freckles.
