10. You are testing Drosophila for the following recessive genes: "spinless" without bristles on the wings; "claret" dark brown eyes; and "hairless" without thoracic bristles. You do a test cross with a heterozygous female for all three genes, and you get the following progeny: spineless 82 wild 380 claret, spinless 130 claret 18 claret, hairless 80 hairless, claret, spinless 323 hairless 140 hairless, spinless 12 The correct distance between sp - cl genes is: a. 0.25 um b. 0.36 um c. 41 um d. 25 um e. 16 um 11.
