In the illustration above, the genotypes of the offsprings are
A.
1 heterozygous smooth : 2 homozygous smooth : 1 wrinkled
B.
1 homozygous smooth : 2 heterozygous smooth : 1 wrinkled
C.
2 homozygous smooth : 2 wrinkled
D.
3 heterozygous smooth : 2 wrinkled
Correct answer is B
The diagram above refers to a PUNNETT SQUARE used in predicting the probable genotypic and phenotypic ratios of a cross. looking at the diagram, we have the ratio
SS : Ss : sS : ss and from the question, we see the genotypic composition is;
1 homozygous smooth : 2 heterozygous smooth : 1 wrinkled
