In cats, some are black, some are orange, and some are calico (fur that is both black and orange). all calico cats are always female. this trait represents two inheritance patterns. List which two and explain how you know

Calico cats, white coat with black and orange patches, have two inheritance patterns an X-linked character and X-chromosome inactivation.

Explanation:

The inheritance patterns in calico cats are called complex inheritance. In this case, the gene that determines color - black () or orange ( ) - is found only on the X chromosome, and is absent on the Y chromosome.

It is clear that the dominance, in this case, is uncertain, although it has been conventionally accepted that the color orange can be dominant over the recessive, something that cannot be demonstrated in the case of calico cats.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
