Tallness (T)in snapdragon plants is dominant to dwarfness (t),and red (C^R)flower color is not dominant to white (C^W).The heterozygous condition results in pink (C^RC^W)flower color.A dwarf red snapdragon is crossed with a plant homozygous for tallness and white flowers.What are the genotype and phenotype of the F₁ individuals?

The heterozygous condition for tallness and red flower color is TtCRCW, while the homozygous recessive condition for dwarfness and white flower color is ttCWCW. When these two genotypes are crossed, we can use a Punnett square to determine the possible genotypes and phenotypes of the offspring. The resulting genotype and phenotype of the F₁ individuals would be TtC^RCW, which is tall and pink in flower color. Therefore, the best choice is D.
