Question

The phenotypic ratio of F2 generation in Mendel's monohybrid cross is 3:2 . State true or false​

Answer 1

Answer:

False

Explanation:

The phenotypic ratio of F2 generation in Mendel's monohybrid cross is 3:1

Answer 2

Required Answer:-

The phenotype represents the physical appearance of offsprings and genotype tells us about the genetic composition.

The parent cell undergoes meiosis and form the gametes i.e. T and t here. They are crossed to form the F1 generation. The pair will be Tt which means all the plants are tall in F1 generation. The condition is heterozygous dominant.

They are selfed or inbred to form offsprings of 3 different genotypes: TT, Tt and tt. There is 25%, 50% and 25% of their chances. Also, TT and Tt will form tall plants. Hence$,$

• Phenotypic ratio = 3 : 1
• Genotypic ratio = 1 : 2 : 1

According to question,

• It is given that, the ratio will be 3 : 2 which is absolutely false. The correct ratio should be 3 : 1.
