I went through the colors of last year's buybacks and it seemed to be popular so I thought I'd do it again! I was the photographer for this year's ICPAR auction album which these photos come from. None of these ponies have been color tested. My observations are conjecture from the visual look of the pony (aka phenotype), extensive knowledge about their parents and siblings, and color tests of siblings and family members. Sires are presumed as always.  Auction #A, 2023 Colt (Archer's Gambit x Surfer Dude's Gidget) This yearling colt is a dark chestnut likely due to sooty which runs in both sides of his family. He was guaranteed to be a chestnut because both of his parents are and will pass one copy on to all of his foals. He didn't inherit his sire's tobiano pinto, but appears to have splashed white 1. His dam and her sire had SW1 and we have verified this through testing of multiple family members. His markings are typical of ponies that have one copy of SW1. They usually aren't visual pintos but are instead flashy to varying degrees. Chestnut: https://www.thecolorfulchincoteague.com/chestnut.html Sooty: https://www.thecolorfulchincoteague.com/sooty.html Splashed White: https://www.thecolorfulchincoteague.com/splash.html  Auction #11, 2024 Filly (Surfer Dude's Riptide x WH Wildfire) This filly was guaranteed to be a chestnut because both of her parents are. She will pass one copy of red/chestnut on to all her foals. Both of her parents appear to have splashed white 1 and she appears to have it as well with her wide blaze and socks. Her dam also had tobiano but she didn't inherit it. Her sire's family often produces dark sooty chestnuts and it appears she will be one as well. She may be a flaxen, which is common in her sire's family, but it's too early to tell.

He has one copy of the cream dilution and will pass the cream dilution on to statistically 50% of his foals. Palominos are chestnuts with the cream dilution so he will pass one copy of red/chestnut on to all of his foals. Palomino: https://www.thecolorfulchincoteague.com/palomino.html  Auction #22, 2024 Filly (Don Leonard Stud II x Milly Sue) This filly is a chestnut tobiano like her sire. She will pass one copy of red/chestnut on to all her foals. Her dam does not have tobiano and her sire does. Since only one parent has it she is heterozygous for tobiano, statistically 50% of her foals will be tobiano. She may have splashed white or another pinto pattern also through either of her parents. The irregular and broken apart look of her pinto markings indicate that she might. Chestnut: https://www.thecolorfulchincoteague.com/chestnut.html Tobiano: https://www.thecolorfulchincoteague.com/tobiano.html Mixed Pinto: https://www.thecolorfulchincoteague.com/mixedpinto.html  Auction #33, 2024 Filly (Maverick x Kachina Mayli Mist) This filly is a palomino like her dam and a tobiano like her sire. She will pass a copy of chestnut on to all her foals and will pass a copy of cream dilute on to statistically 50% of her foals. Without testing we don't know if she has a copy of agouti or not. Agouti is what causes a bay so she may have inherited it from her sire. Since only her sire is a tobiano she is heterozygous for tobiano, statistically 50% of her foals will be tobiano. Palomino: https://www.thecolorfulchincoteague.com/palomino.html Tobiano: https://www.thecolorfulchincoteague.com/tobiano.html  Auction #40, 2024 Filly (Ajax x Grandma's Dream) This filly is a bay tobiano like both of her parents. Since both of her parents are bay there's the possibility she could be homozygous for black or for agouti. She could also be homozygous for tobiano which would mean all of her foals would be tobiano. But without testing we'll have to watch her offspring to see if any of these are true. There's some signs that her sire may have splashed white or another unknown white/pinto pattern. So that possibility exists for her too. Bay: https://www.thecolorfulchincoteague.com/bay.html Tobiano: https://www.thecolorfulchincoteague.com/tobiano.html Mixed Pinto: https://www.thecolorfulchincoteague.com/mixedpinto.html  Auction #90, 2024 Filly (Henry's Hidalgo x Wildest Dreams)
This filly is a black tobiano. We can't tell without testing if she carries recessive red/chestnut. Her bay sire has a chestnut dam so he carries it. Her dam does not have a chestnut parent and has had limited foals but has not produced a chestnut. Both of her parents are tobiano so it's possible she's homozygous for tobiano which would mean all of her foals would be tobiano. We can't know for sure without testing but can watch her future foals to answer these questions.

Another dark bay or brown tobiano is this week's historical pony. This is Dreamcatcher, born in 1997. Her 2010 foal is peeking out behind her in the second photo, he was also a brown. Nothing is known about her parents, despite many of our best efforts. Dreamcatcher's only foal kept for the herd was the short lived Dreamdancer so she has no descendants in the current herd. Browns like Dreamcatcher test the same as bays, but there is likely some genetic difference. The brown tint to her coat and shows us she wasn't black. And she was far too dark to be a regular bay. More about browns on my website: https://www.thecolorfulchincoteague.com/brown.html Dreamcatcher also carried a recessive mutation for a curly coat. Dreamdancer and a 2011 full brother had curly coats. Because it's the recessive version of curly (there's a dominant version too) the sire Wild Bill had to have carried it also. Recessive traits requires two copies to be inherited for the trait to be seen. Since recessive traits can be carried unknown for generations it's unknown where it came from.   This historical pony is the stallion Witch Doctor. He was a dark bay or brown tobiano. He was occasionally referred to as black but his brown nose and the brown in his coat tells us he wasn't. Black ponies on Assateague are often sunburnt but don't look like he did. Witch Doctor was born in 1987 and nothing has been found about his parents, yet. A foal photo of him also shows a dark bay and not a black foal. Witch Doctor had several offspring kept for the herd, Bay Girl and Two Teagues Taco are his last currently on Assateague. For a few years there was a test for brown, but the study was proven to be faulty and the test withdrawn. It's highly likely there's a genetic difference to browns. Many species have a similar type of black and tan coloring. Hopefully research will find out one day! More about brown on my website: https://www.thecolorfulchincoteague.com/brown.html   An add on to Sunday's post about my pony, Misty's Hurricane Izzy. I thought I'd share her non-color test results. Just because I can! Izzy has one copy of DMRT3 which is known as the gait gene. Izzy's not gaited, but I've noticed she'll have some weird transitions between gaits sometimes. I'm told this is common for non-gaited horses with this gene. Her temperament tested as curious and vigilant. That checks out as she's always got an eye out, takes a bit to trust, and is on the hotter side. Her performance tested as Endurance. Lines up with her Arabian ancestry. She has little inbreeding with her Genomic Inbreeding Value at 2.7%. Breed ancestry testing is still in its early stages. The main problem is that most horse breeds are a combo of multiple breeds. Many breeds can't be genetically isolated from another. Chincoteagues don't have a genetic marker that all of them will have so determining if a pony is a Chincoteague through breed testing is impossible. Izzy's a great granddaughter of the Arabian Al-Marah Sunny Jim on her sire's side and the Mustang Broken Jaw on her dam's side. Izzy's ancestry report from Etalon said: -26.1% Near East. That Arabian great grandsire but with a bit of Akhal Teke at 3%. -24.1% North Sea. 13% Icelandic and 8% Shetland. Also 2% Fjord and 1% North Swedish. -21.2% European Heavy Horse. 7% Belgian, 6% Freiberger, 5% Fell Pony, 3% Clydesdale. The most surprising to me, perhaps from the Mustang? -9.9% Ibearian/Spanish breeds. 5% Paso and 5% Andalusian. Little bit of Mangalarga. Not much of that famed Spanish blood in my girl. -9.2% Carriage Horse. 8% Saddlebred and 1% Standardbred. Old American breeds. -7.5% Thoroughbred -2% Exmoor Pony Izzy's ancestry testing also included matching with related ponies. She matched with a descendant of her sire's sire Lightning of Chincoteague, a descendant of her sire's dam Misty II, and a descendant of her damsire Ocean Star.  The last pony in my tested ponies series is my own! If you have a color tested pony and would like me to feature them just message me with their test results and some pictures. My pony Misty's Hurricane Izzy is a Misty descendant and a daughter of chestnut tobiano Misty II's Henry. Izzy's solid black dam Stars Black Velvet was born on Assateague in 1994. Her test results weren't a surprise to me because what I know about her family but there's still things to discuss and learn from! Izzy is a bay and she tested as A/a, or has one copy of Agouti. Agouti restricts black to the points. Because her dam is black and can't have agouti, that means it came from her chestnut sire. Henry's sire is a bay so that's likely where it came down from. She tested as E/e which means she has one copy of extension from her black dam. The combo of extension and agouti are what made her a bay. The small e means she has a copy of recessive chestnut. Since her sire is a chestnut he passed one copy on to her. Chestnuts always pass one copy of chestnut on to their offspring. She doesn't have a dorsal stripe or any other primitive markings and her test reflects that as nd2/nd2. Izzy is obviously a pinto and she tested as TO/n. She only has one copy of tobiano because only her sire is a tobiano. She has a good bit of roaning. While her type of roaning is more common on tobianos with two copies of tobiano, she has it with only having one. In my opinion she has a lot of white and a rather large star to be tobiano only. If she has another white/pinto pattern then it's one that hasn't been found yet. I've run every white test available on the market and she doesn't have any of them. She had three foals with three different stallions, here's what she had: Chestnut tobiano splashed white. Sired by a chestnut tobiano splashed white. Black tobiano. Sired by a brown tobiano. Bay tobiano (a lookalike!). Sired by a homozygous black tobiano.    He's not really a historical pony, but this handsome stallion is the main progenitor of another sooty family I've been tracking. This is 1994 dark bay or brown tobiano Tuffer Than Leather. He never lived on Assateague and was born on Chincoteague. Tuffy was a prolific sire and has descendants on Assateague through his black tobiano daughter Baybe. His granddaughters on Assateague are Randy, Little Miss Sunshine, and CLG Bay Princess. Many of Tuffy's foals are sooty, some very dark sooty. Misty's Twist O' Mist is my go to example of a sooty palomino. Peregrin Took was born bay and as an adult is a shade similar to Tuffy. Chestnut daughter Mahogany's name is self explanatory. Half Chincoteague daughter Cowgirl is a bay only slightly lighter shade than her sire. I'm also seeing sooty in some of Baybe's descendants. Baybe's son Rainbow Boy Ray grew up to be a sooty palomino tobiano. You may be thinking, what? That's a black pinto. In the right light he had a brown nose and flanks. My photos don't quite show that. And he's sunbleached in the headshot. A friend has a foal photo of Tuffy and he was definitely a bay as a newborn foal. He got darker as he grew up which is common of many sooties. The color test of his daughter Misty's Red Dawn also tells us he's not black. She has one copy of agouti. Blacks cannot have agouti because having it makes them bay. Dawn's dam is definitely black so the agoui had to have come from Tuffy. She didn't inherit his sooty though. We know so little about the genetics of sooty. It's all observation right now. Here's what's on my website: https://www.thecolorfulchincoteague.com/sooty.html Have a sooty descendant of Tuffer Than Leather? I'd love to see!    |
