\\What is the phenotype ratio for the offspring in this Punnett Square?
Correct answer: A. 9 round yellow; 3 round green: 3 wrinkled yellow: 1 wrinkled green
- A. 9 round yellow; 3 round green: 3 wrinkled yellow: 1 wrinkled green
- B. 3 round yellow; 3 round green: 3 wrinkled yellow: 3 wrinkled green
- C. 3 round yellow; 9 round green: 1 wrinkled yellow: 3 wrinkled green
- D. 9 round yellow; 3 round green: 3 wrinkled yellow: 9 wrinkled green
Explanation
Four types of gametes, i.e., RY, Ry, rY, and ry were formed in equal numbers in a perfect ratio of 1:1:1:1. When these gametes randomly fertilized each other, a 9:3:3:1 phenotypic ratio was produced among F2 progeny

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.
