In a breeding experiment, the male parent is known to have either two dominant genes (symbolized by AA) or one dominant and one recessive (Aa). These two cases are equally likely. The female parent is known to have two recessive genes (aa). Since the offspring gets one gene from each parent, it will be either Aa or aa.

1. If we suppose n offsprings are all Aa, what is the probability that the male parent is AA?

2. If one offspring is aa, what is the probability that the male parent is Aa?
