I've been conducting some genetics experiments for my Bio/Genetics class and in the most recent one I got some suprising results. I did a cross between Apterous (wingless) flies, and Dumpy (misshappen wings) files. The offspring of the experiment had Wild (normal) wings. I can't explain this occurance. I would think that one allele would be dominant over the other, but instead, I get an entirely different trait. Can anyone help me explain these results, or at least point me in the right direction? I've already thought of the experiments being compromised, but I've done it several times, and I keep getting the same results. I have yet to do an F2 generation.
