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.
The average human has 24 chromosomes, and autistic people have two copies of the 23rd in place of the 24th
There are 46 chromosomes in a normal human cell and 23 in the sex cells. People with down syndrome has 47 chromosomes.
23 pairs for a total of 46 chromosomes (not chromozones) :o)
Dogs are not colorblind naturally, but if they have a problem and are colorblind it can be any color.
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 father has to be colorblind for the daughter to be colorblind because both X chromosomes must have the colorblindness gene in females because the colorblind gene is recessive. If only the mother is color deficient, then she merely passes on the gene to one of the X chromosomes in a female. If both the mother and father are both colorblind, then both X chromosomes in the female are effected and the female is colorblind. There are two scenarios in which a daughter may be born colorblind. 1. The father is colorblind and the mother is a carrier of the colorblind gene. The daughter will be either colorblind or a carrier of the colorblind gene. 2. The father and mother are both colorblind. If this is the case, then all of the children will be born colorblind.
The same for a person who is not colorblind
It has to do with the slight differences in the DNA, ANSWER Colorblindness is sex linked trait. Females are XX and Males are XY. The colorblind gene is only on the X chromosome so if a male has the gene on the X chromosome then he will be colorblind. Females can have it on one X chromosome, but not the other and not be colorblind; however, they are a carrier and can pass it on. For a female to be colorblind both X chromosomes must have the gene.
Nobody really knows, people say cats are colorblind when they are not really. So I would say "No." donkeys are not colorblind

Colorblindness is an X-linked recessive disorder. This means girls (who have the sex chromosomes XX) must have a colorblind X from dad and a colorblind X from mom. Boys only need to have one colorblind X to be colorblind because they have sex chromosomes XY (and have only 1 X). If the dad has it, he has the colorblind X. If the daughter has it, she must have gotten her mom's colorblind X. If the mom is colorblind, then every child they have will be colorblind. If the mom is not colorblind, then she must be a carrier - she must have 1 normal X and 1 colorblind X. Mom is either colorblind (with 2 colorblind Xs) or she is a carrier. Dad is definitely colorblind.
People who are colorblind can have a driver's license for driving a motor vehicle. One just needs to be aware where the red and green are on a traffic light.
Yes, anyone can be colorblind regardless of their race. Colorblindness is a genetic condition that affects the ability to distinguish certain colors, and it is not specific to any particular racial group.
Like 1,000,000.
no color blind people are mainly red-green colorblind or less commonly blue-yellow colorblind
