Awoman with normal vision is pregnant from a man with red-green colorblindness. can they child produce a child that has red green with red-green colorblindness? o
a. yes. it is possible for them to produce a child with red-green colorblindness.
b. no. it is impossible for them to have a child with red-green colorblindness

a. Yes. It is possible for them to produce a child with red-green colorblindness.  

Explanation:

Color blindness is a change in vision that is characterized by the inability to distinguish some colors, especially green from red. Like hemophilia, color blindness is an example of inheritance linked to sex.

Color blindness is determined by an X-linked recessive gene, symbolized by Xd while the dominant allele gene, which conditions normal vision, is symbolized by XD.

Thus we can conclude that it is possible that the couple, exposed in the question, have a child with red-green color blindness. As the child's father already has the recessive gene, which is likely to be passed on to the child, if the mother also has the recessive gene for color blindness, the child is likely to develop red green color blindness.
