The following is a schematic representation of region of the chromosome of fly along with extent of six deletions (Del 1 to Del 6); 
When flies homozygous for the recessive mutations are crossed with flies heterozygous for the deletions, the following results are obtained, in which "m" represents a mutant phenotype and a plus sign (+) represents the wild type. On the basis of these data, determine the relative order of the seven mutant eenes on the chromosome.
