121. The lizards have X-Y chromosome sex determination, but we cannot conclude whether the logus of gene of UV reflection pigment is located on sex or autosomal chromosome.

Why the fact that pigment is expressed in dewlap, a structure found in male cannot confirm that this locus is on Y chromosome?

I appreciate any input!!

Because it could be on an autosomal chromosome?

I give you a bag full of marbles and tell you to close your eyes and remove one marble. You remove a blue marble. Can you conclude that all the marbles in the bag are blue? No.
