Breeding my mare? With her father?

My mare is in the pasture with her father. I don't know much about breeding, but would it affect the colt? Or does he know he's related, which I highly doubt. If it does affect the colt how? They are both extremly quiet.

I certainly hope this is a joke.

I would remove your mare immediately. Horses do not in anyway recognize that they are related and will mate at will. I definitely wouldn't risk the detrimental effects of inbreeding.

Inbreeding horses can produce very bad birth defects in the foal. Definitely remove your mare. They will mate and there are not good results at all. Even if there are not birth defects there is a very high chance the foal will never be very healthy. For the baby's sake do not let them breed.

Actually inbreeding one time rarely cause any birth defects in livestock incidents are no higher then no inbreeding. But its not a good practice to line or inbreed unless you know what your doing and theres a huge stigma some people have about it due to just not knowing anything on the subject.

Why is your mare in a pasture with any stallion? Breeding with a relative increases the chance of obtaining familial tendencies towards birth defects and can magnify any conformational defects or weaknesses.

I agree with everyone else there are too many risk factors to think about if your mare has any conformation problems however slight, if she inherited them from her sire then allowing them to breed will bring those faults to the front. In other words what is a slight fault will be a big fault due to doubling it. The same thing applies to temperament etc. I don't know a lot about horse breeding but I have raised Shiba Inu dogs and from experience know that things can crop up unexpectedly from line/in breeding. It's just not worth the risk if you ask me

I agree with everyone. Inbreeding/linebreeding should not be done unless you absolutely know what you are doing and are prepared for the results.
Breeding should not be done on a whim for that matter. If you don't know for sure that a stallion would recognize his daughter as a horse he should not breed, why are you leaving them together? I don't think you have much business breeding in the first place.

Really? There are so many things wrong here I don't know where to begin. I agree with mls, I do hope is this some kind of joke.
