Solution
The correct option is B G = 1:1, P = 1:1 ∙ Gametes produced by heterozygous tall pea plant is 'T' and 't'. ∙ Gametes produced by homozygous dwarf pea plant is 't'. ∙The cross between these two plants will produce F1 generation with genotypes (Tt and tt) in the ratio 1:1. The phenotypes, heterozygous tall and (homozygous dwarf pea plant) will be in the ratio 1:1.
