Question

The ratio of the offspring of 9:3:3:1 is for the:

Answer 1

The correct answer is the Phenotype.
The phenotypic ratio of 9:3:3:1 is  the ratio associated with a dihybrid cross. It is a classical Mendelian example of independent assortment. It is a result of crossing two organisms that are heterozygous for two traits.

Answer 2

Answer:

phenotype.

Explanation:

Mendel is known as father of genetics. Genotype may be defined as the genetic constitution of an organism whereas phenotype may be defined as the physical constitution of an individual.

When Mendel performed the dihybrid cross ( two distinguish characters at a time), he obtained the phenotype ratio of 9:3:3:1. These two traits can assort independently and follows the Mendel law.

Thus, the correct answer is option (a).
