Question

A pink flowered Snapdragon plant was crossed with red flowered Snapdragon plant. What type of phenotype/s is/are expected in the progeny?

Accepted Answer

, the inheritance of flower colour in Snapdragon (*Antirrhinum sp.*) is a classic example of incomplete dominance. The genotypes are: Red (RR), White (rr), and Pink (Rr) .
The question asks for a cross between a Pink plant (heterozygous, Rr) and a Red plant (homozygous, RR).

Cross: Rr (Pink) × RR (Red)
- Gametes from Pink: R, r
- Gametes from Red: R
- Offspring Genotypes: RR and Rr
- Offspring Phenotypes: Red and Pink

Therefore, the progeny will consist of red flowered as well as pink flowered plants .
