(D) (i) and (iii)
The parental combinations were round green (RRyy) and wrinkled yellow (rrYY). The new combinations appearing in F2 are round yellow and wrinkled yellow — wait, re-checking: parents had round green and wrinkled yellow; new combinations are round yellow (RrYy / RRYY) and wrinkled green (rryy). So the answer is (B) (i) and (iv).
(B) (ii) and (iii)
The correct answer is (D) (ii) and (iii) — No.
Correct Answer: (B)
The parents were round green and wrinkled yellow. New combinations (not seen in parents) in F2 are (i) round yellow and (iv) wrinkled green.
The parents are RRyy (round, green) and rrYY (wrinkled, yellow). So the parental phenotypes are "round green" and "wrinkled yellow." In F2 (from Fig. 8.5), all four combinations appear: round yellow, round green, wrinkled yellow, and wrinkled green. The new combinations — those not present in the original parents — are round yellow and wrinkled green, making option (B) correct. Students must carefully distinguish "new combinations" from the parental phenotypes.
