How would the genotype be written?

[Klatelon]

A man and a woman are both carriers of sickle cell anemia. The man is color blind. The woman is not color blind, nor is she a carrier of color blindness.
How would the genotype of the man be written?

a. S and XY
b. ss and Y to the power of (c)Y
c. Ss and Y to the power of (c)Y
d. SS and X to the power of (c)Y
e. Ss and X to the power of (c)Y

[Arpeet K]

It would be XY^c, or X^cY. It depends on which chromosome the sex linked trait is.
