A snapdragon plant that bred true for white petals was crossed to a plant that bred true for purple petals, and all the F1 had white petals. The F1 was selfed. Among the F2, three phenotypes were observed in the following numbers
white 240
solid-purple 61
spotted-purple 19
Total 320

Two independent pure line varieties having white and green phenotype in their fruit were cross, the all f1 progeny is white fruit. The F2 progeny obtain from selfing show white, yellow and green in ratio of 12:3:1. Which of the following is correct?

Red kernel color in wheat results from the presence of at least one dominant allele of each of two independently segregating genes . Kernels on rr bb plants are white, and the genotypes R— bb and rr B— result in brown kernel color. Suppose that plants of a variety that is true breeding for red kernels are crossed with plants true breeding for white kernels produced F1 were allowed to selfing .what are F2 phenotype ratio ?
