Solution

The correct option is B
Tt

Dominant alleles represented by capital letter expresses itself in both, homozygous condition (AA, TT ) or heterozygous condition ( Aa, Tt ) in F1 generation. Recessive traits express only in the F2 generation ( in case of Monohybrid / Dihybrid cross ) i.e when they are in homozygous condition (aa, tt).
