Three different pure-breeding strains of corn that produce cars with wite kernels were crossed to eaach other. In each case, the F1 plants, were all red, while both red and white kernels were observed in the Ftwo generation in a 9:7 ratio. Results are shown below:

white-1 x white-two F1: red Ftwo: 9 red: 7 white
white-1 x white-three F1: red Ftwo: 9 red: 7 white
white-two x white-3 F1: red Ftwo: 9 red: 7 white

(a) How many genes are there? How many alleles does each gene have? What type of gene interaction does the ratio in the Ftwo indicate?

(b) Show a cross between white-1 and wite-two. Show the genotype and phenotype of the F1 progeny. Show the genotypic classes, corresponding phenotypes and the ratios of the F-two.
