In northeastern Narnia there is a creature known as a chromocat. It comes in three colors, blue, red, and purple. This trait is controlled by a single locus gene with incomplete dominance. A homozygous (BB) individual is blue, a homozygous (bb) individual is red, and a heterozygous (Bb) individual is purple. What would be the genotypes and phenotypes of the offspring if a blue chromocat were crossed with a red chromocat?

Genotype: all Bb

Phenotype: all purple

Explanation:

Blue color chromocat will have the genotype BB.

Red color chromocat will have the genotype bb.

If the two are crossed:

BB   x   bb = Bb, Bb, Bb and Bb

All the offspring will have a genotype of Bb.

A genotype of Bb has a phenotype color of purple.

Hence:

The genotype of all the offspring will be Bb.

The phenotype of all the offspring will be purple.
