How do you tell if inheritance is sex linked, monohybrid, dyhybird, or both or some.?

I am researching drosophila and they have this part with eyes and wings. Are eyes primarliy sex-linked? Or are they other?

How do you tell if inheritance is sex linked, monohybrid, dyhybird, or both or some.?
I believe it is polygenic, only because if the trait has to do with eyes and wings, that affects natural selection. If the trait is only one or another (like a disease, you either have it or you don't, not counting mosaicism) it is monohybrid. If the trait is like height (so many variations) it is polygenic, expressed in a bell shaped curve. It could also be a Dyhybrid only because it is dealing with possibly more than one trait. Sex linked normally pertains to diseases, but it could be that also. I definitely see your problem, but personally I would believe it is polygenic, which basically means the trait is determined by a number of genes, (like eye color, which takes 3 different genes to determine.)
