#Unit 8. Inheritance Biology

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
