What percentage of progenies in F2 generation of a typical monohybrid cross exhibits homozygous condition?

If a cross is made between TT and tt. F1 generation will have genotype Tt. On selfing we will obtain progenies in the ratio of 1(TT): 2(Tt): 1(tt). From here it is clear that 24of the progenies have probability of having homozygous genotype. Hence, 50% of the progenies in F2 generation of a typical monohybrid cross exhibits homozygous condition.
