(Solved)
i) In fruit flies, the gene for red eyes (R) is dominant over the gene for white eyes (r). If a true breeding red eyed female is mated with a true breeding white eyed male, all the offspring are red eyed. However, if a true breeding white eye female is mated with a red eyed male, all the female offspring will be red eyed and the male offspring will be white eyed. Explain this apparent contradiction using genetic crosses.
ii) Work out the ratio of the expected phenotypes of a red eyed female offspring from
the above crosses and a red eyed male.
