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.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
