Now, because we're dealing with a heterozygous female individual, that means one of the X chromosomes will carry the normal gene. The other one will carry the color blind gene. So one of these will be uppercase blue. So let's fill this in as blue. So this is our gene, and the other one will be lowercase C. So let's draw this in with red.
