what colour and pattern discription

chestnut or silver bay ? large blanket or will she go near leopard (spots spread forward each year including on her face)

I would agree. I also disagree that near Leopards are born that pattern- I have had far too many "spots on their backsides" foals and even solids, spot out to near Leopard to believe that!

Great discussion! I'm also on the AP and somehow missed this thread over here. I agree that the OP horse looks PATN1/patn. And thanks so much AppyLady for the great comparison of a suppressed PATN1 blanket versus a secondary PATN blanket.

And rabbitsfizz, I agree with you that the idea of telling a foal's PATN genetics from their appearance at birth seems to have way too many exceptions to be an effective rule of thumb. The research of 'late bloomers' of the PATN genes seem to show plenty of minimal to solid foals with LP who are genetically patterned.

[quote=AppyLady]This morning the Appaloosa Project was comparing pictures of leopard fillies that were thought to be PATN1/PATN1, and those thought to be PATN1/patn1. I don't think cross-posting is allowed, but the pictures were interesting. The H/Z leopards were nose-to-toes (or mostly so) and the h/z leopards were what we would call near-leopards, and showed various levels of expression. I'm sure a lot of people would call them extended blankets. It was mentioned that Patn1 has a wide range of expression, and we really don't know what the bottom end is.

Here are a couple fillies that I raised:

The palomino filly was sired by a smoky black snowcap stallion, and out of a near-leopard mare. Her blanket is about half the size of her sire, which is to be expected since he would only pass on half of his pattern modifiers. She obviously did not inherit Patn1 from her dam. Her blanket has distinct edges, and the spots are medium sized and spaced a good distance apart.

The buckskin filly SHOULD have been a leopard (or near-leopard). Her sire was a full nose-to-toes palomino leopard thought to be PATN1/PATN1, and her dam was a fewspot. All of her full siblings were fewspots or leopards. I fully expected this filly to roan out to be a near-leopard -- at the very least, she should have had the ribbing on her sides and spotted patches on her shoulders. That didn't happen. Her blanket never got much bigger than what you see here, and she didn't develop any more spotting. It's my theory that she is PATN1/patn1, with a highly suppressed pattern. Her blanket has roany edges, and the spots are small and close together -- the "shrunken sweater effect". If suppressors hadn't been present, her blanket most likely would have stretched up to her shoulders.

I realize most people would call the buckskin a spotted blanket. That's what I call her myself, since visually, that's what she is. But genetically, I'd be willing to bet that she is in fact, a near-leopard![/quote]

I found that explanation along with the pics very helpful ,the difference is obvious once someone has pointed it out , thankyou
