Biology

In fruit flies, a grey body is dominant to a black body, andnormal wings are dominant to vestigial wings. Flies areheterozygous for both grey bodies and normal wings were crossedwith flies that had black bodies and vestigial wings. The followingresults were obtained:
Phenotype Number of flies
Grey body/Normal wings 482
Black body/Vestigial wings 472
Grey body/Vestigial wings 103
Black body/Normal wings 92
The results indicate that the genes for wings and body color areon the same chromosome. The recombinant offspring are a result ofcrossing over.
How many map units (expressed as a percentage to thenearest whole number) apart are the two genes?
