A kidney-bean shaped eye is produced by a recessive gene, k, on the third chromosome of Drosophila. Orange eye color, called cardinal, is produced by the recessive gene cd on the same chromosome. A third recessive gene on chromosome three, e, produces ebony body color. Trihybrid females are testcrossed to produce 4000 progeny, as follows: 1761    kidney, cardinal 1773    ebony 128      cardinal 97        kidney 89        ebony, cardinal 6          kidney, ebony,cardinal 8          wild type 138      kidney, ebony What is the distance between genes e and k? What is the distance between genes cd and e?
