Answer:
The percentage for the homozygous dominant trait would be 25%. in the F2 generation.
Explanation:
Suppose true-breeding parents with the different alleles for the same trait are TT (dominant) and tt (recessive) than the cross of these parents will produce gametes T, T and t, t respectively.
These gametes will form offspring ultimately. Produced offspring will be TT (homozygous dominant), Tt (heterozygous dominant), Tt (heterozygous dominant) and tt (homozygous recessive).
Thus, the percentage of dominant homozygous phenotype in F2 would be 25% in respect of the dominant allele which is TT.
