                    How many different types of genetically different gametes will be produced by a heterozygous plant having genotype AABbCc?                                                                                                                                        

    A)              Two   

    B)              Four

    C)              Six                            

    D)              Nine

    Correct Answer: B

    Solution :

                    First pair AA is homozygous, hence it will contribute only one type of genes to gametes, Bb will yield two types of gametes?B and b similarly, Cc will yield two types of gametes?C and c. Hence, \[1\times 2\times 2=4\] types of gametes would be produced having the genotypes             ABC, Abc, AbC and Abc
