Pure tall is denoted by 'TT'.

Pure tall plants are crossed with pure dwarf plants . In the F_1 - generation , all plants were tall . These tall plants of F_1 -generation were selfed and the ratio of tall to dwarf plants obtained was 3 : 1 . This is called :

Pure tall plants are crossed with pure dwarf plants. In the F_(1) generation, all plants were tall. These tall plants of F_(1) generation were selfed and the ratio of tall to dwarf plants obtained was 3:1 . This is called

In an organism, tall phenotype is dominant over recessive dward phenotype, and the alleles are designated as T and t, respectively. Upon crossing two different individuals, total 250 offsprings were obtained, out of which 124 displayed tall phenotype and rest were dwarf. Thus, the genotype of the parents were (a) TT × TT (b) TT × tt (c) Tt × Tt (d) Tt × tt

Tallness of a pea plant is a dominant trait, while dwarfness is the alternate recessive trait. When a pure line tall is crossed with pure line dwarf, what fraction of tall plants in F_(2) shall be heterozygous. Give reasons.

When F_(1) generation hybrid tall Tt is crossed with dwarf tt parent, it is a case of :-

When F_(1) generation hybrid tall Tt is crossed with dwarf tt parent, it is a case of :-

When hybridisation is carried out between a tall (TT) pea plant and a short (tt) pea plant, all the plants (offsprings) show the expression of tallness, because ………………….... a.the expression of tallness is dominant. b.the expression of short is dominant. c.the expression of tallness is recessive. d.the character of tallness in pea plant is not controlled by gene T or t.
