Codominance — Overview & Examples

The tabby genes are inactivated randomly in different cells, resulting in the tabby patterns. The sex chromosomes in calico cats are equally dominantly expressed, resulting in the calico patterns.

The calico genes are inactivated randomly in different cells, resulting in the calico patterns. The autosomal chromosomes in tabby cats are equally dominantly expressed, resulting in the tabby patterns.

The calico genes are incompletely dominant while the tabby genes are codominant, resulting in the difference in patterns.
