The locations of six deletions have been mapped to a Drosophila chromosome, as shown in the following deletion map. Recessive mutations a, b, c, d, e, and f are known to be located in the same region as the deletions, but the order of the mutations on the chromosome is not known. (refer image for contination )

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 genes on the chromosome.
