You have identified that flame wing (fw) is linked to blue eyes (be) and short legs (sl) on chromosome 2. You cross a fw, be, sl fly with flies containing various deletions within the 200 Kb region these genes are believed to be located. Map the gene order based on the following data from these crosses.
Deletion 100-200 has a phenotype of fw+ be+ sl
Deletion 1-80 has a phenotype of fw+ be sl
Deletion 1-50 has a phenotype of fw be+ sl
Deletion 150 has a phenotype of fw be sl+
