Steps in determining gene order in a three-point cross
Identify the non-recombinant progeny
Identify the double-crossover progeny
Compare the phenotypes of double-crossover progeny with the phenotypes of non- recombinant progeny
The characteristic that differs between the double crossover and the non-recombinant progeny is encoded by the middle gene
