A flower has the gene for the colors red and blue. The blue gene is dominant over red. If a plant breeder crossed a red flower with a blue flower, what will the offspring phenotype be?

Explanation:

Let blue gene be BB

Red gene be bb

Since blue gene is dominant the allele is B

while red gene that is recessive has allele b

A cross between the two individual will give,

BB × bb

!

Bb Bb Bb Bb

Genotype=Bb

Phenotype= all blue flowers

Where the offspring have blue flower and non have a red flower.
