QUESTION 11 The location of five deletions have been mapped to a Drosophila chromosome, as shown in the following deletion map. Recessive mutations a, b, c, d and e are known to be located in the same region as the deletions but the order of the mutations on the chromosome is not known. Drosophila Chromosome Deletion 1 Deletion 2 Deletion 3 Deletion 4 Deletion 5 When flies homozygous for the recessive mutation are crossed with flies heterozygous for the deletions, the following results are obtained in which "m" represents recovery of flies with a mutant phenotype and "+" represents recovery of only flies with a wildtype phenotype.
