Question

Tallness (T) is dominant to dwarfness (t), while red (R) flower color is dominant to white (r). The heterozygous condition results in pink (Rr) 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?

• A. ttRr - dwarf and pink
• B. ttrr - dwarf and white
• C. TtRr - tall and red
• D. TtRr - tall and pink

Hint:

Incomplete dominance in snapdragons (*Antirrhinum majus*) is a classic genetic example where heterozygotes ($Rr$) show an intermediate pink phenotype instead of the dominant red color.

Answer 1

The Correct Option is D
