Solution The correct option is C 9:3:3:1 In Mendel's dihybrid cross, the parents are - plants with round yellow coloured seeds (RRYY) and plants with green coloured wrinkled seeds (rryy). The F1 progeny are all round and yellow seeds (RrYy). Self-fertilising the F1 plants gives F2 progeny exhibiting 4 different phenotypes. Yellow round (9), yellow wrinkled (3), green round (3), and green wrinkled seed plants (1). The phenotypes with round yellow seeds, wrinkled yellow seeds, round green seeds and wrinkled green seeds in the ratio 9:3:3:1.
