In Drosophila flies, red eyes (R) are dominant to white eyes (r) and normal wings (W) are dominant to vestigial wings (w). Double heterozygotes WwRr are produced by crossing WWRR with a wwrr. A test cross was made by mating a RrWw fly with an rrww fly. The offspring phenotype numbers were (i) Red-eyed, normal wings: 368 (ii) Red-eyed, vestigial wings: 56 (iii) White-eyed, vestigial wings:336 (iv) White-eyes, normal wings: 40. What is the recombination frequency, as expressed as a percentage, for this cross?
