Help with Drosophila genetics

Featured Replies

Hi! I have recently done a lab experiment with drosophila and I need some help with the results.

 

I mated female vestigial with male apterous and the F1 gen was all wild type. I am trying to reason this but having trouble.

 

If vestigial and apterous are both recessive (vv and aa) then they should produce vvaa F1...not wild type, right? Wild type would be VvAa...or so I thought. Could someone please give me some insight?
