Can only men be colour blind?

More men are color blind than women because the recessive gene for color blindness is carried by women on one of their X chromosomes. And since they have two X chromosomes, the recessive trait is less likely to be expressed. Since men have an X and a Y chromosome, which is shorter, if a mother passes on her X chromosome with the trait of color blindness, her son will have no corresponding gene on his Y chromosome from keeping it from being expressed. So men are color blind more often than women.

No.

Most men are not color blind. Only a small fraction of men have impaired color vision.

But out of all color blind people, most of them are male.

If a woman is a carrier for color blindness in the DNA, only one of her chromosomes will be affected, and for that reason she will not be colorblind. Men, on the other hand, only have one X chromosome, so any time they carry the colorblindness gene, they will be colorblind for sure. Since women have two X chromosomes, both must be affected in order for her to be colorblind.That is why it's easier for guys to be color blind, because they only have one X chromosome. I hope you enjoyed my science lesson

No, all men are not color blind. Only those inheriting colorblind gene from mother on x-chromosome are colorblind.

The gene for color blindness is a recessive allele located on the x chromosome. If a color blind man and color blind woman have one son and three daughters how many will be color blind?

Women can not be colorblind, only men. For questions like these a punnett square is useful. Men can not carry the colorblind trait, but women can. I know this is kind of confusing. When a carrier ( a woman with the color blind trait) has children with a man ( color blind or not) her kids will have 50% chance of having that trait. If its a girl, she will be the carrier. If its a boy, he will have the colorblind trait. SO TO ANSWER YOUR QUESTION: Theoreticaly, 1 of the daughters will be the carrier, and the son will have a 50% chance of being colorblind. Women can be colorblind, its just rare. About every 6400 women one is colour blind and with men, every 80 men 1 is colour blind.


Are babies colour blind when they are first born?

No.


Can dogs be really color blind are scientist true or false?

Dogs can see colour but the only colours they can't see is red and green. Red to them is a light pink and green is white to them.So yes, dogs can see colour it is un-true about being colour blind.


How many percent sons will be color blind if father is colourblind?

Colour perception is carried on the X chromosome. Boys are XY, Girls are XX so in girls, colour perception is enhanced. If colour perception is lost on the X chromosome in boys, the effect is severe and effects between 1 in 12 to 1 in 20 boys. In girls the likelihood of both chromosomes being defective is very slight so colour perception problems in girls are very rare indeed (1 in over 200).


Are stick insects color blind?

No. They see like all other insects see. There are many colours in their eyes which only allows them to see blured colours. Actually yes most of them are colour blind but some see blurred images.

Why are men most likely to be color blind than women?

Men are not just 'likely' to be colour blind, they are the 'only ones' who can suffer from colour blindness. This is because colour blindness is cused by an x-linked recessive gene, that is it can occur only if a person carries 2 of these x-linked recessive traits. Now, females have one X and one Y chromosome,so in no way, they can have 2 X chromosomes.(exception-Klinefelter's syndrome, where thery is XXY trisomy) Only men can have 2 X-chromosomes. Hence, females can only carry the colour blindness gene, while men can 'suffer' from colour blindness.


What is the ratio of girls who are colour blind?

I don't know the ratio but I know that men are more likely to become colour blind because women have a backup gene.
