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?
