2. A flower arranger is growing some flowers in a garden. He has

seeds for red, and seeds for pink plants. Both colours are found or

the same allele as each other. Red is the dominant colour, while

pink is recessive.

a) Using the letter R, what are the possible Genotypes for the red

coloured flower?

b) What is the genotype for the pink flower?

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.
