Let P = purple flowers and p = white, and T = tall plants and t = dwarf. What combinations of gametes could be produced by a heterozygote for both the traits?

The combinations of gametes that could be produced by a heterozygote for both of the traits is PT, pT, Pt, and pt.

The combinations of gametes that could be produced from heterozygous individuals for both traits are PT, Pt, pT and pt.

Explanation:

An individual is heterozygous for two traits, flower color and stem height, with a PpTt (dihybrid) genotype and a phenotype showing the dominant traits, purple flowers and tall stem.

The genes of this individual for the above-mentioned traits contain different alleles, and taking into account the independent segregation of characters, the alleles present in its gametes could be:

Therefore, the traits of its offspring will depend on the alleles for those traits present in the gamete to which they are combined.
