Whаt is the bоnus cоde in the TEVAL survey?
In Drоsоphilа melаnоgаster, cut wings (ct) are recessive to normal wings (ct+), sable body (s) is recessive to gray body (s+), and vermilion eyes (v) are recessive to red eyes (v+). All three recessive mutations are X-linked. A female fly with cut wings, sable body, and vermilion eyes is crossed to a male with normal wings, gray body, and red eyes. The F1 females produced by this cross were mated with cut, sable, vermilion males in a testcross. The following are the progeny resulting from the testcross. V ct s 510 v+ ct s 1 v+ ct+ s 14 v+ ct+ s+ 500 v+ ct s+ 73 v ct s+ 20 v ct+ s 81 v ct+ s+ 1 Total 1200 A. Which gene is in the middle? 2 points. B. What are the distances (in centimorgans) between the gene in the middle (see part A) and each of the other genes? (3 points) C. Based upon your distance calculations, is there crossover interference? Explain your reasoning. (2 points)
