Here is a simple explanation:
Remember that all males have an XY and females have XX, colorblindness is on the X chromosome, and since it is passed on by the X chromosome, this means that females have one good X and one colorblind X . Since colorblindness is recessive, this means the good X can provide the necessary pigments and the female is not colorblind unless she receive two X's that have colorblindness (one from her mother and one from her father), highly unlikely.
On the other hand, since the Y has very few genes on it, the pigment missing in the X carrying colorblindness would not be replaced and thus colorblindness would occur in males with the X colorblindness gene from the mother.

man pppl on here are smart i didn't know that!!!!! :)

∙ 15y agoAbout 5-8 percent of males, but less than 1 percent of females, are color blind in some way or another, whether it be one color, a color combination, or another mutation. The reason males are at a greater risk of inheriting an X linked mutation is because males only have one X chromosome (XY, with the Y chromosome being significantly shorter than the X chromosome), and females have two (XX); if the women inherit a normal X chromosome in addition to the one which carries the mutation, they will not display the mutation, while men have no 'spare' normal chromosome to override the chromosome which carries the mutation.

∙ 11y agoColour blindness is a recessive disorder - meaning that a heterozygous female will not be colour blind.
This is because the other allele (on her other X chromosome) is dominant over the colour blindness allele. Therefore the trait (colour blindness) is not expressed in a female unless she has two copies a the colour blindness allele.

Why and how can we say that it can not. As soon as you do it will happen.

Why is colour blindness more common in males than in females?
Color blindness is a sex-linked trait that is caused by a recessive gene. Sex-linked characteristics occur more often in males because they only have one X chromosome while females have two X chromosomes. The X chromosome holds much more genetic information than the Y chromosome. So, while females need to have two recessive genes to become color blind, males only need one recessive gene to be affected. Therefore, males have a greater chance of inheriting color blindness.
Are women prone to color blindness than man?
Studies show that color blindness affects 8% of Caucasian men and only 0.5% of Caucasian women. Therefore, while the color deficiency is mostly a male dominated affliction, some women are also affected. It is believed that color-blindness comes from a gene on the X chromosome and thus would be part of life from birth. However, it has been discovered that color-blindness can occur with some diseases such as liver disease.
How is red-green color blindness inherited?
You can inherit it from your parents, so it is automatically genetic. Color blindness is a recessive trait, so you only inherit it if both your parents carry the gene.
What are sex-link genes and their effects?
Since males are the only sex to have a y chromosome, only males can get genes that are linked to the Y chromosome. This means that some genetic diseases and conditions are more likely to be male such as color blindness.
Why do females with turner syndrome have a similar incidence of color blindness as males?
Turner Syndrome is a condition where one of the sex chromosomes (X or Y) is missing. In girls this means that they only have one copy of the X chromosome, the same as men have. Color blindness is a recessive condition coded for by the X chromosome. This means that men only need one copy of the 'color blindness' mutation (as they have one X and one Y chromosome) where as girls would require two (a unmutated form of the gene on either X chromosome would mean that it was not expressed due to its recessive nature) In turners there is only one X chromosome for girls, this means that they only require one copy of the mutated gene to express the condition, the same criteria as men
Are only males color blind?
Color blindness is carried on male genes only.
Who does color blindness mostly effect?
Everyone can be affected by monochromatic color blindness. Monochromatic color blindness is a condition where your color blind in only one eye.

Who is more apt to color blindness - males or females?
Genetic red-green color blindness affects men much more often than women, because the genes for the red and green color receptors are located on the X chromosome, of which men have only one and women have two. Such a trait is called sex linked Females (46, XX) are red-green color blind only if both their X chromosomes are defective with a similar deficiency, whereas males (46, XY) are color blind if their single X chromosome is defective. This sentence means that if both of the X chromosomes women are reccesive ten she has a color blindness trait. If the X chromosomes has one dominant X and one reccesive trait then she doesn't have the color blindness trait. The people who have color blindness trait are called a carrier.

What research has been done on color blindness?
Researchers studying red/green color blindness in the United Kingdom reported an average prevalence of only 4.7% in one group. Only 1% of Eskimo males are color blind. The ColorCorrection System was designed to enhance one's Color Blindness and allow one to pass an Ishihara Color Plate Test. The ColorCorrection System has a 100% Success Rate and 100% Guarantee for Passing the Ishihara Color Plate Test.
How is red-green color blindness inherited?
You can inherit it from your parents, so it is automatically genetic. Color blindness is a recessive trait, so you only inherit it if both your parents carry the gene.
Why is colour blindness more common in males?
The genes that produce photopigments are carried on the X chromosome; if some of these genes are missing or damaged, color blindness will be expressed in males with a higher probability than in females because males only have one X chromosome (in females, a good gene on only one of the two X chromosomes is enough to yield the needed photopigments).
What are sex-link genes and their effects?
Since males are the only sex to have a y chromosome, only males can get genes that are linked to the Y chromosome. This means that some genetic diseases and conditions are more likely to be male such as color blindness.
Is blindness only generically inherited by males?
No, but it is almost exclusively a male condition.
Color blindness is a recessive trait. The gene for color blindness is on the X-chromosome. The family tree below shows the trait of color blindness. The only unknown is the mother in the first generation?
(Apex Learning) She has at least one recessive color blindness allele.
