Which of the following statements about red-green color blindness is true?

The statement that anyone with red-green color blindness has a mother who is a carrier is true due to the inheritance pattern of this condition, which is linked to the X chromosome. Red-green color blindness is a form of color vision deficiency that is often caused by mutations in genes responsible for the light-sensitive photopigments in the retina.

In terms of genetics, males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). Because males inherit their X chromosome from their mothers, any male who is color blind must have received the mutated gene from his mother, making her either a carrier (if she has one normal X chromosome and one mutated X chromosome) or affected (if she has two mutated X chromosomes).

In females, a female can be a carrier of the color blindness gene if she has one affected X chromosome, but she would need two affected X chromosomes to actually express the condition. Therefore, it's accurate to state that all males with red-green color blindness have mothers who are carriers of the gene, directly linking male color blindness to maternal genetics.

The other statements do not accurately reflect how red-green color blindness is inherited or expressed. For instance, it does not affect both genders equally since it is more common
