It is rare in females because they have 2 X chromosomes so they have the trait that stops colorblindness, but men have an X and Y chromosome so the Y chromosome does not back up the other X chromosome and makes men have more of a chance to get colorblindness that doesn't mean girls cant get it, just means girls have a better chance to stop it.

∙ 10y agoThe reason is the gene is located on the X-chromosome. Since men only posses one X-chromosome they are more likely to be affected as they only need to have 1 defective gene. Considering women have 2 X-chromosomes they would need to have the defective gene on BOTH chromosomes to suffer from color blindness.
Women have 2 X-chromosomes. There is no guarantee which one she will pass to her son, so the only way a woman will know for sure if she is passing on color blindness to her son/daughter is if she herself is color blind.

∙ 12y agoColor blindness is a sex-linked trait carried by the X chromosome. Males have an X and a Y chromosome (XY) and females have two X chromosomes (XX).
If a female has an allele for normal vision and an allele for colorblindness, she will have normal vision. This is because normal vision is dominant over colorblindness, which is the recessive trait. However, a male only has one X chromosome, so if he receives an allele for colorblindness, he will be colorblind. This is also true for normal vision.

Waht is a sex-linked condition that more often affects males?
color blindness
How often does color blindness occur?
1 out of 12 men. 1 out of 200 women.
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.
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 is an inherited disorder that appears more often in males than females?
Those transmitted on the Y chromosome (girls don't have a Y) Examples include reg/green color blindness.
Can a person be colored blind?
Yes,Color blindness is a color vision deficiency, characterized by a persons inability to differentiate between various colors. Although color blindness is genetic in nature, i.e. passing from one generation to another, a substantial amount of cases are related to damage caused to eye, brain or nerves. Though rare, exposure to certain chemicals can also trigger color blindness. Although color blindness is technically a wrong term to refer to this eye problem, it is preferred over color vision deficiency, owing to the simplicity of pronunciation as well as understanding for a lay man. Although it's a minor disability, there are certain situations wherein being color blind can cause difficulties for the individual in various walks of life. Simple things like choosing clothes or reading analytical diagrams may seem like a tedious task for a color blind individual. Let's have a detailed look at some of the prominent color blindness facts.Facts About Color BlindnessEnglish scientist John Dalton was the first person to present a paper on color blindness and as a mark of respect for his contribution, color blindness is also referred to as Daltonism. Interestingly, John Dalton was a color blind himself. Some simple yet interesting color blindness facts are mentioned below.Color Blindness SeverityThe severity of color blindness is usually categorized into four parts.Slightly color blind.Moderately color blind.Strongly color blind.Absolutely color blind.Scientifically, absolute color blindness or complete color blindness is referred to as achromatopsia or monochromacy. Complete color blindness is most often associated with eye conditions such as amblyopia and nystagmus.Color Blindness InheritanceOne of the most interesting facts about color blindness is about inheritance of the disorder. Color blindness is one of the genetic disorders in humans. As the most common form of this deficiency is related to X chromosome or color blindness chromosome, color blindness tends to be more common in males than in females. But color blindness genetics also suggest that even though women are not color blind themselves, they are very active carriers of color blindness. Interestingly, a mother is bound to pass her red-green color blindness to all her sons, but its less likely for the father to do the same.Red Green Color Blindness FactsApproximately 99 percent of all color blind people suffer from red-green color blindness. Statistics reveal that around 75 percent of people suffering from red-green color blindness have problems with green perception, while the remaining 24 percent have problem with red perception. But this doesn't mean that a person suffering from red-green color blindness tends to mix up between red and green colors only. The fact is that the problem prevails in the whole color spectrum. The most common form of color blindness is deuteranomaly, a form of red-green color blindness. Red-green color blindness is a recessive sex linked, and therefore we see that more men are color blind than their female counter parts.Color Blindness TestThere are several types of color blindness tests. The most commonly used color blindness tests arePseudoisochromatic plates.Arrangement test.Anomaloscope test.Among the various tests for color blindness, anomaloscope, which measures the quantitative and qualitative anomalies in color perception, gives the most accurate color blindness results. Ishihara plates are also popularly used for testing color blindness, but they are comparatively less accurate. Color blindness deficiency can be corrected to a certain extent by wearing color correcting lenses. A person wearing these correcting lenses wears two different colored lenses in his/her eyes. Read more on, tests for color blindness.These were some of the common color blindness facts, which everyone ought to know. Although color blindness is classified as a disability, one of the most interesting facts about color blindness is the advantage that the color blind people tend to have over people with normal vision. One such advantage is the ability of color blind people to penetrate certain camouflages with ease. As of today, there is no accepted treatment of color blindness, but there is a hope that we will have one very soon.Source view related links.
Is colorblindness a dominant or recessive trait?
Color blindness is an inherited trait that can be passed on through reproduction but it has some peculiarities. It is recessive and not very prevalent in the gene pool. Because of this, color blindness does not appear very often in the population. In addition, it is a sex-linked gene on the X chromosome. Thus males only have one gene to express color vision. If it happens to be the recessive allele, then males are color blind. Females, on the other hand, must have both alleles recessive in order to be color blind.source: ciese.org/curriculum/genproj/activity35.html
How is color blindness transmitted?
Color blindness is a color vision deficiency, is the inability to perceive differences between some of the colors that others can distinguish. It is most often of genetic nature, but may also occur because of eye, nerve, or brain damage, or due to exposure to certain chemicals. For more information see: wikipedia.org/wiki/Color_blindness
Are parents carriers in color blindness?
Not exactly "carriers" since that word refers to someone who has a disease but exhibits no symptoms. However there is a genetic component to color blindness. It doesn't mean all children of a couple will have it though as men have i more often than women and in some types of color blindness the woman must have 2 genetic defects to pass it on.
Is color blindness an infectious disease like the common flu or influenza?
No, it is not an infectious disease like a cold or flu. Color blindness occurs in people who have a specific genetic trait for it. They often have adapted to the visual disorder by the time they are tested to find out they have it.
How do you become colorblind?
Carrots Unfortunately there is no true cure for color blindness. However, 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 many animals are color blindness?
there are 1000005000 kinds of blindnesses
