Fruit fly larvae are either 'rovers' or 'sitters.' Rovers will move to a new location after feeding, while sitters will stay put. The behavior is mostly innate. Using the optimal foraging model, describe the conditions under which it would be advantageous to a rover and under which it would be advantageous to be a sitter. Briefly explain why.
If you had a fruit fly (Drosophila melanogaster) that was of phenotype $A,$ what test would you make to determine if the fly's genotype was $A / A$ or $A / a ?$
What is the sexual phenotype of fruit flies having the following chromosomes? $$\begin{array}{ccc} & \text { Sex chromosomes } & \text { Autosomal chromosomes } \\ \text { a. } & \text { XX } & \text { all normal } \\ \text { b. } & \text { XY } & \text { all normal } \\ \text { c. } & \text { XO } & \text { all normal } \\ \text { d. } & \text { XXY } & \text { all normal } \\ \text { e. } & \text { XYY } & \text { all normal } \\ \text { f. } & \text { XXYY } & \text { all normal } \\ \text { g. } & \text { XXX } & \text { all normal } \\ \text { h. } & \text { XX } & \text { four haploid sets } \\ \text { i. } & \text { XXX } & \text { four haploid sets } \\ \text { j. } & \text { XXX } & \text { three haploid sets } \\ \text { k. } & \text { X } & \text { three haploid sets } \\ \text { l. } & \text { XY } & \text { three haploid sets } \\ \text { m. } & \text { XX } & \text { three haploid sets } \end{array}$$
