Question

Can someone please help me solve this problem?

I am completely lost on this. I am having a hard time with finding the linkage with blue eyes and others.

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.

When an F1 female is backcrossed to a triple mutant male, the following

1,000 progeny are produced:

Wild type eyes, wings, and bristles: 90 females, 89 males

Wild type eyes and bristles, vestigial: 83 females, 98 males

Wild type eyes and wings, spineless: 37 females, 35 males

Wild type wings and bristles, blue eyes: 36 females, 34 males

Wild type wings, blue eyes, spineless: 92 females, 88 males

Wild type eyes, spineless, vestigial: 34 females, 39 males

Wild type bristles, vestigial, blue eyes: 33 females, 37 males

Blue eyes, spineless, vestigial: 90 females, 85 males

Calculate the map distance between blue eye and any linked genes from the above progeny. Show your work
