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: B
Explanation
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
