Question

Quizplus · Accepted Answer

The gene for color vision is on the X chromosome and is recessive. Thus, color-blindness is an X-linked-recessive disorder resulting from a mutation in the gene. If a male inherits this gene from his mother, he will express color-blindness. If a girl inherits this gene from her mother, she will only express color-blindness if her father is color-blind.
