The possible genotypes for the red colored flower are RR and Rr.
The genotype of the pink flower is rr.
Explanation:
The color of the flowers is determined by the genes that they inherit from the parents.
It is given that red is the dominant trait and pink color is recessive. Let R denote the dominant gene and r denote the recessive
The presence of a single copy of the dominant gene makes the flower have dominant color.
Thus the genotype of red flower will be Rr or RR. So the genotype rr makes the flower pink.
