Out of these 40 haploid spores, 5 haploid spores can grow on a –ade –his plate and 35 haploid spores cannot grow on a –ade –his plate. of these 35 haploid spores, 15 can grow on a –ade plate, 15 can grow on a –his plate, and 5 cannot grow on either –his or –ade plates. calculate the percentage of recombinant gametes you collected.
