A pink flowered Snapdragon plant was crossed with red flowered Snapdragon plant. What type of phenotype/s is/are expected in the progeny?
Red flowered as well as pink flowered plants
Only pink flowered plants
Red, Pink as well as white flowered plants
Only red flowered plants
, 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)
Therefore, the progeny will consist of red flowered as well as pink flowered plants .
