Explain the inheritance of one gene with reference to stem height of Garden Pea plant.

Text Solution

Verified by Experts

Mendel crossed a true breeding tall pea plant with a true breeding dwarf.
He allowed F-1 tall plants for self pollination. In F-2 both tall and dwarf plants were produced in the ratio 3 : 1. 1
Re-appearance of dwarf character in F-2 generation indicates that alleles for tallness and dwarf character have segregated during gamete formation,

Genotypic ratio TT:Tt:tt
1:2:1
Phenotypic ratio : 3:1
Detailed explanation with genotypic and phenotypic ratios 5 marks)
