A person first crossed pure-bred pea plants having round-yellow seeds with pure-bred pea plants having wrinkled-green seeds and found that only A-B type of seeds were produced in the `F_(1)` generation. When `F_(1)` generation pea plants having A-B type of seeds were cross-bred by self-pollination, then in addition to the original round-yellow and wrinkled-green seeds, two new varieties A-D and C-B type of seeds were also obtained.
(a) What are A-B type of seeds ?
(b) State whether A and B are dominant traits or recessive traits.
(c) What are A-D type of seeds ?
(d) What are C-B type of seeds ?
(e) Out of A-B and A-D types of seeds, which one will be produced in (i) minimum numbers, and (ii) maximum numbers, in the `F_(2)` generation ?
