can both women and men be colour blind?

Answer 1

Yup. It's more prevalent and in more varieties among males, though, especially blue/green color blindness.

Answer 2

I hope the people saying no have learned something today!

Someone has said that only men can be colour blind because the gene for colour blindness is on the Y chromosome, which only men have. This is incorrect.

The gene is actually on the X chromosome. Men have only one X chromosome, whereas women have two. Because the gene is recessive a woman can only be colour blind if both her X chromosomes have the gene - having a colour blindness gene on only one X chromosome means its effect is suppressed by her matching dominant normal gene on the other X chromosome.

Men, on the other hand, do not have this second X chromosome, so a colour blindness gene on their single X chromosome has no chance of being suppressed.

Hence, it does occur in both men and women, just it is far more common in men. Roughly speaking it occurs in 8% of men and 0.4% of women.

Then there are types of colour blindness, some are more common than others. I myself am protanopic. When I mention that I'm colour blind people think I see in black and white, which is very rare.

Answer 3

.....Yes both men and women can be colour blind, however it's more likely men will be. Maybe around 1 in 6 men are colour blind compared to 1 in 100. The gene however is always passed from the mother. Hope this helps

Answer 4

Yes, but it is much rarer in women. The commonest types are caused by genetic defects on the X chromosome, of which women have 2 but men only 1. A woman needs both chromosomes to be faulty to be colour blind, which can and does happen, but is fairly unlikely.

Answer 5

Color blindness is typically a genetic condition, and it is much more common in men than in women. Approximately one in 12 men has at least some color perception problems. Less common, acquired deficiencies stem from injury, disease, or the aging process. Also, although not called "color blindness," when people age, their corneas typically turn yellowish, severely hampering their ability to see violet and blue colors.

How do things look?
Many people think anyone labeled as "colorblind" only sees black and white -- like watching a black and white movie or television. This is a big misconception and not true. It is extremely rare to be totally color blind (monochromasy - complete absence of any color sensation). There are many different types and degrees of colorblindness - more correctly called color deficiencies.

i always thought only men were...but i guess women can be too

Answer 6

According to what I have read, only men have red/green colour blindness but women can have blue/yellow colour blindness.

Answer 7

more men than women are colour blind. the gene for colour blindness is recessive.
a man inherits x chromosome form his mother and y chromosome form his father, if the mother is carrying the gene for colour blindness then he show problem.
a female will inherit 2 x chromosomes form both parents and will not show the colourblindness because the unaffected x chromosome will be dominate over the affect x chromosome. however if both x chromosomes are affected then the women will be colourblind.

Answer 8

Yes.
Color Blindness, defect of vision affecting the ability to distinguish colors, occurring mostly in males. Color blindness is caused by a defect in the retina or in other nerve portions of the eye. The first detailed report on this condition was written by the British chemist John Dalton, who was himself afflicted with it. Total color blindness, in which all hues are perceived as variations of gray, is known as achromatopsia or monochromatism. This condition is congenital, extremely rare, and affects men and women almost equally. Partial color blindness, called dichromatism, consists generally of the inability to differentiate between the reds and the greens or to perceive either reds or greens; infrequently, the confusion may involve the blues or the yellows. Dichromatism is the most common form of color blindness, affecting about 7 percent of men and less than 1 percent of women. Dichromatism is identified as a sex-linked hereditary characteristic. Color blindness also may occur as a temporary condition following a serious illness.

Answer 9

Women can be colour blind but statistically, men are much more likely. 8% of men compared with 0.4% of women so it's a much larger problem for men.

Here are some stats

1 in 12 people have some sort of color deficiency. About 8% of men and 0.4% of women in the US.

0.38% of women are deuteranomalous (around 95% of all color deficient women).

0.005% of the population are totally colour blind.

0.003% of the population have tritanopia.

Protanomaly occurs in about 1% of males.

Deuteranomaly occurs in about 5% of males. It's the most common color deficiency.

Protanopia occurs in about 1% of males.

Deuteranopia occurs in about 1% of males.

Answer 10

Remembering back to my college days, both men and women could both be color blind. However, men are often more than women. It is more prevelent in men because of the recesive gene that causes color blindness more often shows up in men than in women.

Answer 11

Colour blindness is only limited to men.
