* Parents' trait then add %chance that traits from parents will appear. if both parents have same trait, this %chance is even a lot higher.
* Inbreeding add %chance that bad traits will appear.
* Animal Husbandry is only partially on the Curve. The curved value (effective skill) allows you see traits at that level (not true for bred in captivity trait which requires 60 numerical to see even on epic). But the actual value (numerical) is used for computing the number of traits you can breed.*Lastly, breeder's Animal Husbandry and horses generation affect affects the minimum and maximum number of traits that will appear in a horse. (Currently the maximum number of traits experienced on one animal in game is ??9 at 90+ AH)
Examining an animal will show traits, if one has the required skill level:
* 40 (22.54) skill: "It looks unusually strong and healthy." (Has a higher resistance to disease.)
* 41 (23.19) skill: "It has a certain spark in its eyes." (Affects breeding? <s>Will not die of old age?</s> Disproved, see talk.)
* 60 (60) skill: "Bred in captivity."
(All "?" are unconfirmed, traits with a * are removed by a [[Genesis]] cast)
