The girls will have a 0% chance of being color-blind, but they will be carriers of the gene 100%.
as previously stated, there is a 100% certainty that the son of a color blind mother will be color blind.The chances of any daughter being color blind are a bit more complicated.If the father is color blind, and the mother is as well, there is a 100% chance of the daughter being color blind too.If the father is not, then the daughter of a color blind mother will not be color blind, though there is a 100% certainty that she will be a carrier, and so there is 50/50 chance that any of her sons will be (actually slightly more, if we account for the chance that her future partner may be color blind as well).If we accept that the prevalence of color blindness in the male population is about 5%, then the likelihood of any daughter from a color blind mother and some random father is about 5% as well.
Color blindness is an X-linked trait, so if a mother is a carrier of the trait on one of her two X chromosomes, her female children have a 50% chance of carrying the trait but a 0% chance of being color blind. Her male children will have a 50% chance of being color blind and carrying the trait. The only way a female can display the trait of color-blindness is if her father is color-blind and her mother is a carrier of the trait.
Any female offspring will not be color blind, but they have a 50% chance of carrying on the trait. Any male offspring will have a 50% chance of being color blind. The gene is located on the X chromosome and females would have to have a color-blind dad and a mom who is at least a carrier to even have the possibility of being color-blind. (X'X') Males just have to get the X chromosome carrying the trait, then they will be color blind, since males only have one X chromosome (X'Y)
0 percent. for the daughter to be colorblind, she needs 2 "blind" alleles. the father will supply a normal allele, but the mother may give her daughter the "blind" allele. If it is a daughter, the chances of being a carrier is 50%, the chance of being normal is 50%. Both scenarios will not cause colorblindness
I have looked at many websites and they all say cattle are color blind but nothing about bison being color blind so the best estimate I can make is that bison are not color blind.
yes you can=]
Woman carrier genotype = XCXc (where XC is the normal allele, and Xc is the affected allele) Man who is not color blind must have genotype = XCY Possible genotypes of children are: XCXC , XCY, XcXC , and XcY only one possible (out of 4) will be color blind (and only if they have a son). Therefore, there is a 25% chance that the child will be color blind.
you can't see color
No it is actually the opposite. Men are more prone to color blindness than women. The gene that causes color blindness is a sex linked gene, it is on the X chromosome. Color blindness is recessive, and since males only have one X chromosome they have a much greater chance of being color blind, whereas females have two X chromosomes. Females would need two recessive alleles in order to be color blind, which is very rare
Color Blindness is most commonly the result of hereditary reception of a genetically defective X chromosome. The chromosome usually comes from a carrier mother, and has a 50% chance of being passed to her son. A daughter of the same mother will have a 50% chance of also becoming a carrier, and is only likely at risk of becoming color blind if the father is color blind.
The most common disadvantage of being color blind is not being able to see all colors.
