In your next experiment, you do a three-point cross with three genes that are linked in the C. elegans. A mutation in se gene causes the worms to move slow, a mutation in jv causes the worms to move in circles and a mutation in ru causes the worms to move fast. These are the progeny phenotypes and numbers that you received: jv^+ ru^+ se^+ 37 jv^+ ru^+ se 2 jv^+ ru se 14 jv^+ ru se^+ 146 jv ru se^+ 2 jv ru se 35 jv ru^+ se 154 jv ru^+ se^+ 10 a. Determine the order of the genes on the chromosome. b. Determine which progeny contain single crossovers and which contain double crossovers and indicate where among the genes the crossovers occurred. c. Calculate the map distances among the genes.
