Tested Pony: Sweet Island Dreams

My friend Rebekah at Hart’s Island Pony Ranch has tested more of her ponies, including two mares born on Assateague, so we're going to go over their test results. Starting with Sweet Island Dreams. Dream was born on Assateague and is a daughter of Don Leonard Stud II and CLG Bay Princess. The first photo is one I took of her as a foal, looking quite bewildered at the chaos of Pony Penning!

Dream tested as E/e which wasn't a surprise since she's a buckskin and her sire is chestnut. The big E means she has black and the little e means she has recessive red/chestnut. Since she's a buckskin she should have at least one copy of agouti. Agouti restricts black to the points making a bay, and buckskins are bay with the cream dilution. Dream has one copy of agouti that she likely inherited from her buckskin dam.

Since she's a buckskin she should have one copy of the cream dilution. And that's what her test showed as CR/n.

She tested as nd1/nd2 which means she might have primitive markings like a dorsal stripe. She doesn't but her foals could based on what the sire has.

Dream tested as homozygous for tobiano pinto or TO/TO. That means she inherited a copy of tobiano from each of her parents. And she'll pass a copy on to all of her foals so they will all be tobiano. Many homozygous tobianos have cat tracks or roaning but she doesn't.

An exciting part of her results is that she tested as having one copy of EDXW3 or Eden White 3. Eden Whites were only discovered this year and she's one of the first two Chincoteagues to be found to have it. It's so new we don't completely know how it can interact with tobiano yet. I have eyed her sire as having something else beside tobiano, perhaps this is it. More testing and research is needed!

She's expecting a 2025 foal by Cyclone II. The foal is guaranteed to be a tobiano pinto and a 50% chance of being a cream dilute. The foal will be tobiano and then could be bay, chestnut, black, buckskin, palomino, or smoky black. Quite a few possibilities!

If you have a tested pony and would like me to feature them shoot me a message with their info and some pictures!
