In drosophila melanogaster, the common fruit fly, the typical wild type fly has long wings and red eyes. A genetics student obtained a vial of double mutant flies that have shortened wings and white eyes instead of the typical longer wings and red eyes. The student bred several generations of each fly together and obtained the following results.
Phenotype Number of Individuals
Long wings, red eyes 2031
Long wings, white eyes 482
Short wings, red eyes 463
Short wings, white eyes 2024
Calculate the number of map units between the genes that encode for the short wing and white eye characters.
