  1. Polysomic segregation ratios from random bivalent paring without double reduction for all possible combination of parental genotypes. For each parental combination the proportions of 0 (nulliplex): 1(simplex): 2 (duplex): 3 (triplex): 4(quadruplex) genotypes as expected in the offspring are shown
