Coat Genetics | Overview
The Coat Genetics section provides a simple overview of the in-game breeding genes and the coat colors or patterns they represent within The Tackroom.
Please note that The Tackroom’s in-game genes do not always accurately reflect real-life horse genetics. To keep the system consistent and avoid confusion, this Breed Archive uses the in-game gene names and classifications when referring to coat colors, patterns and breed-appropriate genetics.
Here you can quickly look up which in-game gene belongs to which coat variation or pattern to help you choose the most breed-accurate horse for NEP breed standard competitions and events.
Within NEP breed standard classes, both Common and Uncommon coat colors are considered breed-appropriate and are eligible to receive full coat points. The distinction between these categories simply indicates how frequently a particular coat is found within the breed and does not affect judging or scoring.
Points will only be deducted when a horse is shown with a coat color, pattern or gene classified as Unrealistic for that breed.
Coat judging is based on whether the selected in-game genes are considered realistic for the breed being shown (10 points). An additional 2 points may be awarded based on how realistically the resulting coat color and pattern are represented visually in-game.
What about Chimeras?
While chimera horses are relatively common within the in-game breeding system, they are not considered a true inheritable coat gene or pattern. Because of this, chimeras will generally not be permitted in NEP breed standard-focused competitions and classes.
This rule is not intended to discourage creativity or unique horses, but rather to help maintain a fair and consistent judging environment for realism-based events. In real life, true chimerism in horses is considered extremely rare and is viewed more as a genetic mutation than a standard coat variation.
