When a cross is performed between RR (red) and Rr (pink) in Antirrhinum, the phenotypic ratio in the F1 generation would be:
C. 2 Red: 2 Pink
Answer:
In the F1 generation when a cross is performed between RR (red) and Rr (pink) in Antirrhinum, the phenotypic ratio would be:
C. 2 Red: 2 Pink
This is because all the offspring (F1 generation) will inherit one dominant allele (R) from the RR parent, resulting in the red color, while the other allele they inherit from the Rr parent is recessive, causing them to be pink. So, the phenotypic ratio in the F1 generation is 2 red and 2 pink.
