Q1. A fruitfly with red eyes and leg bristles (genotype RrBb) was mated with a white-eyed fly lacking bristles (rrbb). Five hundred offspring were counted, with the follow results-

58 Rrbb offspring; 62 rrBb offspring; 200 RrBb offspring; 180 rrbb offspring.

Based on these results, how much distance is between these two genes on chromosome?
