Name 3 physical differences between male and female Drosophila. What is body size, wing size, genitalia color, presence/absence of sex combs on forelimbs, or abdomen shape (any 3). Developmental Stages for 400 Home
Heredity for 400 Why must virgin females be used in genetic crosses of Drosophila? What is that females are capable of storing sperm from multiple partners and using it to fertilize eggs at a later time, which could skew results. Home
