In snapdragons red flower colour (CR) is incompletely dominant to white flower colour (CW). The heterozygote has pink flowers. Normal broad leaves (LB) are incompletely dominant to narrow, grass-like leaves, (LN). The heterozygote has intermediate leaf width. If a red-flowered, narrow leaved snapdragon is crossed with a white-flowered broad leaved one, what will be the phenotypes in the F1 and F2 generations, and what will be the proportions of the different phenotypic classes? (You must draw a branch diagram to provide the answer for the F2)

Round seed is dominant over wrinkled. Yellow cotyledon is dominant overgreen. Full pod is dominant over constricted. The genes for these traits arefound on separate chromosomes. If a trihybrid plant is self-fertilized, whatproportion of the progeny will have round seeds in constricted pods?Express answer in fraction form.
