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.

In the plants, due to mutation in the mitochondrial genome causing cytoplasmic male sterility can be influenced by the nuclear gene (Rf), which is dominant over the cytoplasmic mitochondrial genome. If a male sterile plant is pollinated by the fertile male plant with homozygous (Rf)condition, the progeny obtained in F1 will have
