Modifiers

Color Modifiers

Modifiers alter the appearance of the base coat but do not dilute it.

Flaxen (F)

Flaxen is a recessive modifier that lightens the mane and tail of chestnut horses. Depending on expression, flaxen can range from a slightly lighter mane and tail to a nearly white mane and tail.

Inheritance

Because flaxen is recessive, a horse must inherit a flaxen allele from both parents in order to visually express it.

Expression

Flaxen only affects chestnut horses. Bay and black horses may carry flaxen but will not visually express it.

Silver (Z)

Silver is a dominant modifier that affects black pigment. It lightens the mane and tail while having no effect on red pigment.

Inheritance

Only one copy of silver is required for expression.

Expression

Chestnut horses may carry silver but will not visually express it because they do not produce black pigment.

Sooty (Sty)

Sooty is a dominant modifier that adds dark hairs throughout the coat. Expression can range from subtle dark shading to heavy darkening across the entire body.

Inheritance

Only one copy is required for expression.

Expression

Sooty can affect nearly any colour.

TheseGray genes affect howis a horsedominant changesmodifier that causes progressive depigmentation over time.

Gray (G)

Gray causes a horse to gradually lose pigment as it ages.

A gray horse is born its original colour and slowlygradually lightens overas time.it ages.

Inheritance

Only one copy is required for expression.

Expression

Gray can occur on any base colour.

Examples:

• Bay → Gray
• Black → Gray
• ChestnutBay → Rose Gray
• PalominoChestnut → Rose Gray
