In a plant, smooth seeds (S) are dominant
over wrinkled seeds (s) and green seeds (G)
are dominant over yellow seeds (g). A plant
homozygous for smooth and green seeds is
crossed with a plant having wrinkled and yellow
seeds. The F1 offsprings are self crossed to
produce F2 generation. If a total of 160 offsprings
are produced, how many plants are expected to be
having wrinkled and green seeds in F2 generation,
according to a typical Mendelian cross?
A 90
B 30
C 20
D 10
