Answer:
The correct answer would be either the X or Y chromosome.
Sex-linked traits are the traits controlled by the genes present on the sex chromosomes.
In humans, there are two sex chromosomes X and Y.
Human females are homozygous X that is, XX whereas human males are heterozygous for sex chromosomes that is, XY.
Examples of sex-linked traits are hemophilia (X linked recessive disorder), colorblindness et cetera.
