Is color blindness a dominant or a recessive trait?
Color blindness is a recessive sex linked trait.
What two colors are confused most in color blindness?
Red and green
Is color blindness evident at birth or late onset?
Most of the time, color blindness is first realized at a child's first formal vision examination, usually between the ages of 8 and 10. If the color blindness is severe (most of the time, it is a relatively mild form) then an alert teacher may suspect it at an earlier age.
Who discovered that color blindness was a disease?
John Dalton "discovered" color blindness after he was looking at a Pelargonium zonale(a kind of flower). Dalton saw the flower as blue, whereas it is in actuality, pink. Dalton noted this fact in 1792

At Antarctica
Most people affected by mild color blindness have trouble seeing shades of?
green, yellow
What is the most common fatal genetic disease in the US Huntington's disease color blindness hemophilia cystics fibrosis?
Cystic Fibrosis 1/3300 children affected Duchenne Muscular Dystrophy 1/3600 boys affected (Color blindness is not fatal, BTW)
Which is NOT true of color blindness?
It is not true that color blindness is most common in females. Color blindness is most common in males and approximately 8 percent of men have it.
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 do color blind people see when looking at red?
they most likely see green as if it is the most common type of colour blindness red/green colour blindness he/she would see green i think :S
Does colorblidness apper in brith or later on in life?
Color blindness is genetic and so is present at birth. There are three types of color-blindness, also known as color vision defect. The first is red-green color blindness and is the most common. The second is blue-yellow and the third is complete lack of color vision. For each type of color blindness, rather than seeing the colors as they are, one would see varying degrees of intensity of the particular color, or not see the color at all, resulting in shades of brown or grey. The gene for color blindness is carried on the X chromosome, therefore more males than females are affected.
Is partial blindness a symptom of diabetes?
Most likely no.
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.

A color blind son inherited this trait from?
his mother because color blindness is a sex-linked trait that is found on the X chromosome, which is inherited from the mother, as opposed to the Y chromosome, which is inherited from the father. So a male can only inherit the gene for color blindness from his mom.
