A true-breeding white strain of flower was crossed with a true-breeding orange strain. All of the F1 progeny were white in phenotype. When the F1 offspring were crossed with one another, the following offspring phenotype frequencies were obtained in the F2 generation: F2: 98 White

34 Orange

11 Yellow

Using this information, postulate the role of mutant genes and their products in producing the observed phenotypes:
(a) designate alleles and give the general genotypic formula for parental strains and the F1,
(b) give the general genotypic formula that defines each color class and
(c) explains the phenotypic ratio obtained [say what it is] (See attached Table 1), AND
(d) diagram/draw a metabolic pathway that explains the formation of each pigment (or lack thereof).
