Males have an X and a Y chromosome thus denoting males as XY. Traits carried on chrosomes 1-22 are autosomal traits. Traits carried on the X and Y chromosomes are sex linked traits. Not all traits on the X and Y chromosome are to do with sexual characteristics eg colour blindness is a trait found on the X chromosome.
Sexlinked chromosomes determine the gender, meaning we only have 1 of them. We have 22 pairs of autosomal.
