Cat coat genetics affect the coloration, pattern, length, and texture is a complex subject, and many genes are involved. Cat coat genetics can produce a variety of colors and patterns.
Great visuals to explain cat coat colors
The color of cat fur is due to the size, shape and distribution of the melanin (black pigment) or phaeomelanin (red pigment) granules in the hair.
The UC Davis Veterinary Genetics Laboratory offers feline DNA tests that verify parentage, assess coat color and genetic traits, and determine genetic predisposition to health conditions.
This page is a simplified version of cat genetics based on Mendelian inheritance where each trait is given a symbol and is dominant, recessive or co-dominant. In cats, some traits are monogenic...
Most of the visible traits used to demonstrate human genetics, such as attached earlobes and tongue rolling, are NOT determined by single genes; these pages review the evidence.
