With sex linked traits (the allele is found on the X chromosome) males are either affected or not (they have the defective allele or they don't). Women have two copies of the allele and can be a carrier.
Because it travels on the X Chromozome. It has to 'infect' all of the Xs to affect the person. If it only affects one X on a woman (XX) then she will be able to pass it onto he child, but she will not be affected. It has to be all of the Xs. A man will be affected if he gets it, because there is only one X to infect (XY).
No. Men are XY. Colorblindness is carried on the X chromosome. Since the Y chromosome is much smaller, it does not carry all the same information as X. To be a carrier for a condition, you must have something to cover it up. A man can be colorblind or colorsighted, but he cannot carry colorblindness. Only women can.
colorblindness is a sex-linked disease. This means they are diseases affected by chromosomes on the X and Y chromosomes. Two chromosomes determine your sex. XX means you are a girl, XY means you are a boy. Colorblindness is located on the X chromosome. Since guys only have one X chromosome, they can either have colorblindness or not have it.
Color blindness is a gene expressed in the Y chromosome, which only males give during sexual reproduction.
Boys can't be carriers of colorblindness because if they have one allele for colorblindness it will show because they only have one X chromosome.
you look gay
the allele for colorblindness is recessive and located on the X chromosomes
Color blindness is sex linked.
Yes. Two normal-visioned parents can produce a color blind child only if both the parents have are heterozygous. To determine the phenotypes of the parents, you will have to look at their parents.
There is really no cure for total colorblindness. However, serious color deficiencies can be corrected by specially tinted lenses in contacts or eyeglasses.
Each parent must have the recessive allele for colorblindness.
it cant because it is a thing you get from your parents
A male with hemophilia does in fact carry the genes and can pass them on to his daughters, so yes, some boys (if they have hemophilia) are carriers.
no they cant
Colorblindness is usually a genetic trait. There is no more a cure for genetic colorblindness than there is for blond hair.
No you must not choose any diverse colorblindness
they can
I dont think colorblindness matters you just wont see colors and your favorite color might be grey... but if you are fully blind you are going to have many problems because even though you cant see color you can see shapes and figures.
The proper name for colorblindness is color vision deficiency.
As of 2016 there is no cure or treatment for colorblindness.
Sex linked
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.
it could be a dog's name and it cant be a boys name.
