Genetic combinations
Cats have different colours, but there are only two types of pigments: eumelanin (black) and phaeomelanin (red) and it is present on the X chromosome, meaning it is a gene linked to sex.
They are co-dominant alleles, since in the case of having the two, they do not mix but both appear.
Silver, agouti, dilution and other characters are inherited regardless of sex, as they are located on other pairs of chromosomes.

This gene is always present in the DNA of all cats, but it is not always visible since, being a gene linked to the Agouti gene, it is only expressed when the cat is striped and not solid.
The tabby Mackerel is characterized by its vertical and thin stripes and in the tabby Blotched, also known as classic tabby, the lines are wider and stands out for the swirl formed on both sides.
