In radishes, flower color may be red, purple, or white. The edible portion of the radish may be long or oval.  When only flower color is studied, no dominance is evident, and red x white crosses yield all purple. Determine the appropriate allele symbols and indicate which genotypes lead to which phenotypes.       If the F1 purple plants described above are interbred, what will be the genotype and phenotype ratios in the F2 generation?       Regarding radish shape, long is dominant to oval in the typical Mendelian fashion. What will be the phenotype ratios in the F2 generation of a cross between a true-breeding red, long radish and a white, oval radish?
