【Abstract】 Using the model of broad and narrow way,the paper introduces a new approach in the explaining of a few basic concepts in the Morgan Law.The paper introduces a thorough inquiry into the applying condition of the three-factor crosses,and finds the source of the difference between the crossover frequency (F_C) and recombination frequency (F_R) of the non-adjacent factors in the three-factor crosses in Neurospora crassa.更多还原
