Web9 de abr. de 2024 · Most aspects of the fur phenotypes of common cats can be explained by the action of just a few genes (Table 6-2). Other genes, not described here, may further modify these traits and account for the phenotypes seen in tabby cats and in more exotic breeds, such as Siamese. For example, the X-linked Orange gene has two allelic forms.
