  Two pea plants one with round green seeds (RRyy) and another with wrinkled yellow (rrYY) seeds produce progeny that have round, yellow(RrYy) seeds. When  plants are selfed, the  progeny will have new combination of characters. Choose the new combination from the following. (i) Round, yellow             (ii) Round, green (iii) Wrinkled, yellow       (iv) Wrinkled, green (a) (i) and (ii)                      (b) (i) and (iv)                    (c) (ii), and (iii)                   (d) (i) and (iii)
