Are the human sex chromosomes also carrying the genes for the eye color like in Drosophila melanogaster (fruit fly)? Or are they separated?

I've learned about the sex linked traits, but the teacher never really made this clear.

Sex chromosome (chromosome 23) only carries sex info

Not sure but I believe not. But sex chromossomes do not carry only sex linked genes, and if diseases are sex linked is because the original wild type alelles are in the sex chromossome. I do know that certain color blindness are sex linked. But if eye color were sex linked it would be easy to notice because of resulting patterns where all males in a family have blue eyes or vice-versa. I believe that is not the case. However eye colors may be determined by the action of more than one gene and one of them could be in the sex chromossome.

they are separated in humans. there are some traits that are sex linked, but mostly diseases. you will learn about sex linked traits soon.
