Drosophila has four pairs of chromosomes: the sex chromosomes (XX in the females

Drosophila has four pairs of chromosomes: the sex chromosomes (XX in the females; XY in the males) and three pairs of autosomes. You are studying a new mutant strain with blue eyes. You wish to know if blue eye colour is a dominant mutation and on which chromosome the blue eye locus can be found. When you cross a pure-breeding female blue-eyed fly with vestigial wings and spineless bristles to a male fly with wild type eye colour wings and bristles all of the F1 progeny are completely wild type. An F1 male is backcrossed to a triple mutant female producing the following progeny:wild type eyes wings and bristles:72 females 69 maleswild type eyes and bristles vestigial:83 females 77 maleswild type wings blue eyes spineless:52 females 43 malesblue eyes spineless vestigial:62 females 58 malesa.Is the mutation dominant or recessive? Explain.b.Since you know that the locus for vestigial wings is on chromosome 2 and the locus for spineless bristles is on chromosome 3 what chromosome carries the locus for blue eyes? Show your work including the step-by-step reasoning you used to arrive at your answer.c.When an F1 female is backcrossed to a triple mutant male the following 1000 progeny are produced:wild type eyes wings and bristles:90 females 89 maleswild type eyes and bristles vestigial:83 females 98 maleswild type eyes and wings spineless:37 females 35 maleswild type wings and bristles blue eyes:36 females 34 maleswild type wings blue eyes spineless:92 females 88 maleswild type eyes spineless vestigial:34 females 39 maleswild type bristles vestigial blue eyes:33 females 37 malesblue eyes spineless vestigial:90 females 85 malesCalculate the map distance between blue eye and any linked genes.
