Correct answer: C. 1/16
- A. 9/16
- B. 3/16
- C. 1/16
- D. 2/16
Explanation
F1 plants gave F2 progenies exhibiting 4 different phenotypes: Round yellow (9), wrinkled yellow (3), round green (3), and wrinkled green seeded plants (1). Hence, the ratio obtained is 9:3:3:1.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
