The lakes of northern Minnesota are home to many similar species of damselflies of the genus Enallagma that have apparently undergone speciation from ancestral stock since the last glacial retreat about 10,000 years ago. Sequencing which of the following would probably be most useful in sorting out evolutionary relationships among these closely related species?

You cross a true breeding normal corn plant with a true breeding plant with variegated seed coat and colorless endosperm. You suspect the genes are linked, so you cross one of the resulting normal offspring to a true breeding variegated, colorless plant. What are your expected results if the genes are completely linked?
