What does the flow – chart represent?

Question

Observe the flow – chart and answer the following.

i) What does the flow – chart represent?

ii) What is the phenotype characters in F₁ generation?

iii) What is the Genotype, Phenotype ratio of F₂ generation?

iv) What laws of inheritance did you understand by this flow – chart?

Answer 1

i) The flow – chart represents a monohybrid hybridisation between a pure breed Tall (T) and a pure breed dwarf (t) plants resulting first filial generation. On self pollinating with F₁ generation the new breed have any combinations of T, t came in F₂ generation.

ii) In the phenotypic characters in F₁ generation all are dominant that is (T) Tall,

iii) Genotype ratio in F₂ generation is 1 : 2 : 1 Phenotype ratio in F₂ generation is 3 : 1

iv) understand that 

i) the law of dominance 

ii) law of segregation proposed by Mendel.
