If you wanted absolute consistent leopard foals therefore, you would need a fewspot or snowcap (ie LpLp) who is homozygous for PATN-1 - then every cross with an Lplp (regardless of whether they have PATN-1) would result in a leopard.

Alternatively, you could get a guaranteed leopard through a cross between a LpLp horse with no PATN-1, and a PATN-1PATN-1 horse with no lp.

Your mare has a 50% chance of passing a Lp gene, and a 50% chance of passing on a PATN-1 gene. I won't put any maths here as I'm on a train, but the long and short of it would be it depends on the chosen stud, and it would be down to chance as to whether she gives you a leopard foal. I'm pretty certain it isn't a guarantee.

She is lovely though; huge congrats! <3 Looking forwards to seeing her on the ABLB in a few years. ^.^

Spirit Fox was a leopard too so I have really high hopes for this girl. I'd love the added color, but aside from her farther I don't think there are very many strong color ABLB boys to match her too. Oh well whatever I get I just hope it's strong :)
