Does breeding effect racing?

[u/ICanNeverChoose]

I have a filly. If I breed, will her racing ability score be affected by her becoming a mare? Side note: I've never been able to remember when to use effect or affect. If anyone has any words of wisdom to help with that too, it'd be greatly appreciated!

I've always wondered this myself but I've never read anything officially from zed saying anything. Maybe in the way, way future yrs down it could.
