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.

Who is most likely to be affected by color blindness?
Color blindness is more common in men than in women, with an estimated 1 in 12 men being affected compared to 1 in 200 women. This condition is usually inherited and is more prevalent among Caucasian populations.
In a survey 16 women out of 20 000 were found to be colour blind What is the expected frequency of colour blind males in this population?
Not all forms of color blindness are hereditary. There are three distinct types of hereditary color blindness, each with different frequencies in the human population, and with distinct genetic causes. Red-green color blindness is more common among males than females, but blue-yellow color blindness is not. Talking about color blindness in general, there is no reliable ratio of male-to-female prevalence.
What kind of non Mendelian trait is color blindness?
Color blindness is an example of an X-linked recessive trait, which is a type of non-Mendelian inheritance. This means that the gene responsible for color blindness is located on the X chromosome, and the trait is more commonly expressed in males than females.
What chromosome does color blindness effect?
Color blindness is typically linked to the X chromosome. The most common form, red-green color blindness, usually affects males more than females because they have only one X chromosome. If a male inherits a faulty gene for color vision on his X chromosome, he will likely experience color blindness.
Explain why the incidence of color blindness is higher in male than females?
Overall, colorblindness is much more common in males than females due to the fact that it is a sex-linked trait. The gene for colorblindness is carried on the X chromosome. Since this is a recessive condition, males will be more likely to express it due to the fact they only have one X chromosome while the females have two.

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.
Who is most likely to be affected by 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.

Why is red-green color blindness not contagious?
Colour blindness is a usually a genetic (hereditary) condition (you are born with it). Red/green and blue colour blindness is usually passed down from your parents. The gene which is responsible for the condition is carried on the X chromosome and this is the reason why many more men are affected than women
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.
