It's because it's, what we call, a "sex-linked disorder." You see, men have "xy" chromosomes, and women have "xx" chromosomes. In a sex-linked disorder, all "x" chromosomes in either of the genes have to be affected. if you see an affected x chromosome, it would look something like this "xa". The "y" chromosomes don't become affected, I don't think. Women who have only one x chromosome affected are called "carriers," meaning they aren't affected by the disorder, but they carry it in their genes and can pass it on to their offspring. They don't ALWAYS pass on to the child, but it CAN happen. So why is it easier for men to become colorblind? They have less x chromosomes. If you need more help understanding how that works, Google "Colorblindness and punnet square." The Punnet Square is very important to add to your research! if you're curious.
The most common form of colorblindness is red-green colorblindness, which includes both protanopia (difficulty distinguishing red and green colors) and deuteranopia (difficulty distinguishing red and green colors as well). These types of colorblindness are more common in males than females.
Color blindness is sex linked.
it is a genetic trait carried on the X chromosome. Males have only one X chromosome, while females have two. If a male inherits the colorblindness gene on his one X chromosome, he will have the condition. However, females would need to inherit the gene on both X chromosomes to be colorblind.
Alopecia is more common in males than in females.
the allele for colorblindness is ressecive NOT dominant. more common in males because they have one x chromosome and women have two, if a deformity is found on the x chromosome in a woman, it can be masked by the other, but still have some sort of side effects, in a male, since he has one, he is effected the most. he has no other genes to mask it.
Colorblindness is characterized by not being able to tell apart two colors when they are the same value. Colorblindness is an x-linked trait, so it is much more common in males than females.
Males.
Red Green colorblindness is more prevalent in males but can occur in females as well.

males dealing with colorblindness
females have xand males dont
Men Have XY chromosomes. women have XX chromosomes. To get Hemophilia, all of your X chromosomes have to be affected. as you can see, it is much easier for a man to get it than a woman.
Alopecia is more common in males than in females.
Colorblindness is usually a genetic trait. There is no more a cure for genetic colorblindness than there is for blond hair.
No, the term "red-green colorblindness" means that you cannot tell the difference between red and green. There are several different types of colorblindness; red-green colorblindness is the most common kind. For example, another kind is blue-yellow colorblindness, where a person cannot tell the difference between blue and yellow. All types of colorblindness are much more common in men.
