Parental generation red flower of snapdragon male rr x female white rr. T, r, y, and a are dominant alleles. Since r is dominant over r, the individuals with genotype rr and rr will have the dominant phenotype. It can be determined by doing a test cross for example, a test cross between two organisms with same genotype, rr, for a heterozygous dominant trait will result in offspring with.
