Correct Answer - B
First pair AA is homozygous hence, it will contribute only one type of gene to gametes, Bb will yield two types of gametes-B and b similarly, Cc will yield two types of gametes-C and c. Hence, `1xx2xx2=4` types of gametes would be produced having the genotypes ABC, ABc, AbC and Abc.
