A carrier is an individual who has a normal phenotype for a recessive trait, and yet can still pass the recessive allele onto his or her offspring . Which of the following is true: Only sex-linked traits can be carried.
if individual is carrier and normal for phenotype of recessive trait that means the genes are present on sex chromosomes(most probably on X chromosome) in heterozygous form. due to heterozygosity one normal allele is present in individual which gives normal phenotype but it is carrier. this one defective allele pass to offspring and offspring also either affected of carrier.

6. Hemophilia is a sex-linked trait. A person with hemophilia is lacking certain proteins that are necessary for normal blood clotting. Hemophilia is caused by a recessive allele so use "XH” for normal and "Xh" for hemophilia.

Red-green color blindness is a sex-linked trait, with the normal vision phenotype being dominant (C) and the color blind (c) phenotype being recessive. If you are male and your father is color blind, what is the chance (expressed as a percentage) that you will inherit his trait for color blindness? What if your mother is a carrier for color blindness (but your father is not color blind), what is the chance of you being color blind? Make sure...
