A man with freckles and a women without freckles with 3 kids with freckles and 1 without what is the genotypes of the parents and children?

The man must have a dominant gene for freckling and a recessive gene for no freckling. The woman has both recessive genes for no freckling. Therefore, there should be a 50% chance of getting the freckling gene and freckle in this family. If they had more children, chances are 50/50 that the baby will freckle.
