In the Primula plant, the blue flower color is due to malvidin, a pigment encoded by the completely dominant gene (M). Presence of only the recessive gene (m) leads to white flowers. The P locus controls pigment synthesis in the M locus such that dominant gene (P) stops pigment production, and recessive gene (p) allows pigment production. Two plants both having the MmPp genotype were crossed. a. What is the phenotypic ratio of the offspring? b. What type of gene interaction is exhibited by the flower color in Primula? c. What would be the probability of getting plants that are pure-breeding for blue flower color?
