Q Monohybrid Crosses (please include screenshot of your simulations) You may realize that choosing a lot of different types of flies make it difficult to analyze inheritance patterns. Your next tasks will focus on analyzing single traits within flies to determine how they are inherited. 1. Reset all flies in the design tab. 2. Design a male fly with vestigial wings and cross it with a wild-type female 3. Add the results to your "Lab Notes." 4. Mate the offspring of this cross. 5. Based on these two crosses you probably have an idea about how vestigial wings are inherited. Q. Is VG recessive or dominant

1. VG is recessive 2. This is because in both the cases, F1 offspring are showing the normal wings or wild type (+) . In cross 1 , female is wild type and male is vestigial wings . So both the male and female offspring of the cross will have normal . In F2 the offsprings are showing recessive pattern .
