184517 In Morgan's experiment with Drosophila, when yellow bodied white eyed female was crossed with brown bodied red eyed male and their \(F_{1}\) progeny were intercrossed. What was the percentage of recombinants in \(F_{2}\) generation?

2 A unit of distance between genes on chromosomes, representing \(1 \%\) cross over.
3 A unit of distance between genes on chromosomes, representing \(50 \%\) cross over.
