Just had a question about hatching: When hatching is it only the parents' traits that have a chance to manifest on the offspring, or do the grandparents' traits also come into play?
Baby pets inherit a semi-random mix of talents from both parents. Any of the 10 talents and 10 derby abilities can pass to the baby. If a grandparent talent passed to a parent, it can then pass to a baby, but if it didn't transfer to the parent, it's gone and the baby can't get it. Keep in mind that both locked and unlocked talents can pass, so not seeing it doesn't mean it isn't there. Sometimes talents pass "hidden" for generations, then pop up when you least expect them.
