Question

Red-green color blindness is due to an X-linked recessive allele in humans. A widow’s peak (a hairline that comes to a peak in the middle of the forehead) is due to an autosomal dominant allele.
Consider the following family history:

A man with a widow’s peak and normal color vision marries a color-blind woman with a straight hairline.
The man’s father had a straight hairline, as did both of the woman’s parents.

Use the family history to make predictions about the couple’s children.
Drag the correct label to the appropriate location in the table. Not all labels will be used.
