Polygenic inheritance of wheat kernel color controlled by two additive genes

Each number 1 allele (either A1 or B1) adds a unit of color, but number 2 alleles (A2 or B2) add no units of color. Pure-breeding parents (one dark red, one white) produce dihybrid F1 with dark pink kernel color. Five phenotype classes are predicted among F2 progeny in a ratio determined by the total number of A1 plus B1 alleles in the genotypeEach number 1 allele (either A1 or B1) adds a unit of color, but number 2 alleles (A2 or B2) add no units of color.
