              What is the probability (percentage or fraction) of each of the following sets of parents
              producing the given genotypes in their offspring?

              Parents                    Genotype                    Probability

              a. AA x aa                 Aa
              b. Aa x Aa                 Aa
              c. Aa x Aa                 aa
              d. AaBb x AaBB             AaBB
              e. AaBb x AaBB             AaBb
              f. AaBb x AaBb             AABB

            ClassOf1 provides expert guidance to College, Graduate, and High school students on homework and assignment problems in
                          Math, Sciences, Finance, Marketing, Statistics, Economics, Engineering, and many other subjects.

              a) AA x aa                                   Aa

                        When AA x aa is crossed, it will result in offspring with genotype Aa, which could be
              clearly seen in the following punnet’s square. The gametes which will be donated by either
              parents will be A and a.

              Cross between AA x aa
