Answer:

This means that the alleles are co-dominant.

Explanation:

However, calico cats are calico for a different reason. The reason calico cats are two different colors is due to something called X inactivation. In females, cells only need one X chromosome, so each cell independently chooses an X to inactivate. The inactivated X chromosome is called a Barr body.

So, the calico pattern appears in female cats because the color gene is located on the x chromosome and depending on which chromosome you inactivate, that cell will express a different color. This is also why you only find female calico cats.

Different kind of plant species needs the assistance of fire to establish, to reproduce, or to germinate.
