Calculation of Three Point Test Cross: The recombination percentage or unit distance between genes is worked out by calculating the crossing over percentage between different genes. Suppose number of crossover progeny between genes A and B is P, between genes B and C is Q, between genes A and C is R, and total progeny is T. read more
