A critical examination of recent studies on colour inheritance in horses

Abstract

It seems probable that chestnut always breeds true. Therefore the placing of C (chestnut or yellow) at the bottom of the scale probably represents the condition of nearly all breeds of horses. Epistatic to It is H (black). Next comes, in the breeds studied, B (bay or brown), epistatic to both the preceding.G (gray) is next higher. Next is R (roan), which is probably always evident when present1 and which probably merely causes a sprinkling of white hairs, without otherwise affecting the colour. Finally, we have W (white).
