In cats, some are black, some are orange, and some are calico (fur that is both black and orange) All calico cats are always females. This trait represents two inheritance patterns. This two and explain how you know. please help.

Calico cats are predominantly female because they’re colouring is related to the X chromosome.

Have a great day <3  (I love cats)

In cats, one of several genes controlling fur color is located on the X chromosome. The gene has two versions, or alleles. One form of the gene codes for orange fur (XB), and the other form codes for black fur (Xb). While it's difficult to say which allele is dominant and which is recessive, since only one is ever expressed (see below), let's say, for the sake of argument, that orange is dominant to black. Ordinarily, this would mean that an animal inheriting one copy of each gene (genotype XBXb) should have orange fur. Surprisingly, a female cat heterozygous at that locus (XBXb) will not be orange. Instead, her coat will be a patchwork of orange and black, a condition known as tortoiseshell. Male color expression is straightforward. Because only one allele exists for the gene in each cell, it will be expressed. And all males have only B or only b. There are no heterozygotes, because the Y does not carry the allele.
