How to Create Purple Plants by Breeding Red and Blue Plants

What would the genotypes and phenotypes of RR x BB be?

Genotype: ________

Phenotype: ________

A) Genotype: RB, Phenotype: Purple

B) Genotype: RR, Phenotype: Red

C) Genotype: BB, Phenotype: Blue

D) Genotype: RB, Phenotype: Blue

Genotype and Phenotype of RR x BB:

The genotype of RR x BB would be RB, and the phenotype would be purple.

If you breed a red plant (RR) with a blue plant (BB), the resulting genotypes would be RB and RB. The phenotypes of the offspring would be purple. Purple is the result of the combination of red and blue pigments in the plants. A Punnett square is a simple tool often used in biology to predict the genotypes of offspring in a cross.

In this scenario, crossing a red plant (RR) with a blue plant (BB) would result in all offspring having the genotype RB. This would correspond to a phenotype of purple, assuming that red and blue blend to produce purple in this particular plant species.
