True-breeding tall plants with white flowers are crossed to true-breeding dwarf plants with purple flowers. The F1 plants were tall with purple flowers. The genes that affect these traits independently assort. If the F1 plants were allowed to self-fertilize, the expected ratio of the F2 generation would be

A cross is made between a green four-o’clock and a white four o’clock. Green chlorophyll synthesis is inherited via the chloroplasts, which are maternally inherited in this species. If the white plant provides the pollen, the expected outcome of the offspring would be

Two genes are 22 map units apart on the same chromosome. A true-breeding GGhh individual is crossed to a true-breeding ggHH individual. The F1 offspring are mated to gghh individuals. If this testcross produces 1000 offspring, how many of them would you expect to be GgHh?
