You successfully isolate an hsf2/hsf2; hsf3/hsf3 double mutant stock. You cross this plant to an hsf1/hsf1 plant and then self-pollinate the F1. You want to recover at least 10 triple mutant homozygous to evaluate the phenotype. How many plants do you need to genotype to expect to recover 10 triple mutant plants?
