Document Summary
Choose the best and most specific answer from the following five choices for #7 - 11. Any answer may be used once, more than once, or not at all. Use the following information to answer questions #25 - 32. You are breeding a species of colorful, tropical flies whose wild type individuals have a purple abdomen, green thorax, and blue head. Each of these traits is controlled by a single locus, and all three loci are on chromosome #3, though you don"t know their relative positions. Fortunately, there are recessive, mutant alleles of each gene that result in a fly having a black abdomen (b), orange thorax (o), and silver head (s), respectively. You crossed a true breeding female, wild type fly with a male expressing the black abdomen, orange thorax and silver head. You then took females from the f1 generation and bred them to their father until you had 10,000 little maggots.
