colorblind means that colors look like different colors to a colorblind person Colorblindness is caused by a defect in the X chromosome which is why males (XY) are more likely to be colourblind than females (XX). In a female the defect would have to be in both chromosomes, in the male the defect just has to be in one. Most commonly colorblind people cannot distinguish between red and brown or blue and green.
Dogs are not completely colorblind, but they have limited color vision. They primarily see in shades of blue and yellow, and may have difficulty distinguishing between red and green.

Why is colorblindness a sex-linked trait? Descendants of colorblind hemophiliac man both disease are sex- linked? why do non of the children have either hemophila or colorblind
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.
African grey parrots have the ability to see colors, including a wider spectrum than humans due to an additional type of photoreceptor in their retinas. They are not colorblind and can distinguish different colors.
If Mary's mother is colorblind, and therefore carries the colorblind gene on one of her X chromosomes, then Mary would inherit that gene as well. If Mary's father is colorblind, he would have to pass on his X chromosome with the colorblind gene to Mary, making her colorblind too. If only Mary's mother is colorblind, Mary's father is likely not colorblind.
the song is about how you can't see in color
Perhaps.We belive that most tarantulas are colorblind; this is called dyschromatopsia.This does not mean there are some tarantula species with other less severe color sensibility, like dichromacy.
No, Taylor Lauter is not colorblind.
All dogs are colorblind.
Not necessarily. The allele for colorblindness is recessive. For a female, in order to be colorblind she must have to recessive alleles for colorblindness. Example: XcXc would be colorblind. XCXc would be a carrier for colorblindness, but not colorblind. For a male, because colorblindness is a sex-linked gene, he only needs one allele to be colorblind. Example: XcY is colorblind. XCY is not colorblind.
100% of all male offspring will be colorblind. 0% of all femal offspring will be colorblind.
They are born colorblind, they don't just become it.
