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





e. TTRR--tall and red

Tallness (T) is dominant to dwarfness (t), while red (R) flower color is dominant to white (r). The heteroz?
The answer is D.





Crossing -- dwarf red flower x homozygous tall white flower


Genotype -- (ttRR) x (TTrr)


Genotype segregation -- (t) (t) (R) (R) x (T) (T) (r) (r)


F1 generation -- All (TtRr)


Phenotype -- Tall %26amp; Pink
