Chapter 5 and 6 of Callie’s Star are posted!
This blog is largely a rerun of last year’s May post on Indy’s color, until the last two pictures.
“The expression of Leopard Complex (LP gene) includes several components: mottled skin around the muzzle, anus, genitalia, and eyes, and progressive roaning of pigmented coat areas with age. (My underlining.) White spotting may also be present, with pigmented leopard spots tending to occur on the white spotting background of heterozygous horses. The mutation is an incomplete dominant and expression of Leopard Complex is variable ranging from absent to extreme white patterning.” (UC Davis genetic testing site.)
Indy has an Appaloosa with spots father and a quarter horse mother. When I bought her, I didn’t look too closely (because color wasn’t why I bought her), and I didn’t think she had inherited any Appaloosa color genes from her father. Her mom being a solid colored quarter horse, didn’t have any Appaloosa genes to donate!
Indy at about nine months old. Dark bay, Dec. 2014.
But then she shed her winter coat and became a roan! Thus, she did get one copy of the LP gene–from her dad!! One copy is fun–a horse of a different color every season and every year! I happy with only one LP gene copy though. Horses with two copies of the LP gene may have “Congenital Stationary Night Blindness (CSNB) which is the inability to see in low to no-light conditions.” (UC Davis genetic testing site.)
Indy, June, 2015. 14.1! 860 lbs yearling. Roan!
Indy, October 2015. 14.2&1/2 hands 910 pounds, yearling. Back to bay! Winter came again and while the mottling on her skin stayed visible, her longer dark winter coat and covered the roan!
Shed-out #2 and she is lighter than in 2015!Indy, May, 2016, two, 15 hands, 960 lbs. Roan! And her mane switched sides!! Her tail is starting to go gray.
Another bay winter coat, but it is a bit lighter than previous years, and does (if you look really close in person) have some white in it.Indy, December, 2016. 15.1, 1070 lbs, coming three! Bay!
I put in a series of spring pictures because I had a lot of fun watching her roan out again in 2017Indy, April 7th, 2017. Looks bay to me… She is also wet because there was a show the next day.
Twelve days after that and she was a dapple! I have seen this “spring shedding dapple effect” in other horses. I always get a kick out of it. The dappling largely disappears when the shedding is complete.April 28th, 2017. Thanks Ed Armstrong for the picture!
Three weeks later and she was looking like an “varnish roan”. Her summer coat is definitely lighter as a three-year old and her tail is more than half gray now!Indy. May 17th, 2017. 15.1 1050 lbs.
Indy Dec. 5, 2017. Coming 4. 15.2 1100 lbs. Bay again, but there is a lot more white in there.
By February, she measured 15.3.
May 23, 2018. Four years old. Still 15.3. 1190 pounds. He tail is completely gray now.
Interestingly, she is darker in May 2018 compared to May 2017, and I think she is completely shed out. He tail is all gray and her mane (that we cannot see) is salt and pepper. Up on her neck is a white spot from where she scraped it. Her scrapes tend to come in white, and stay white!
She is no longer in cow horse training (I was sad) because her hock is slightly bothering her post bone chip surgery (2017). She is great at the walk and trot, but hard stops and roll backs cause her to take off with one or two off-balance steps. She seems to be thriving in her new job as a walk-trot mountain horse! She may return to loping in the future, but for now, that can wait.
i am liking this job! nice scenery, too! u can see my two colored mane! it blew over,
We are heading to the Pecos Wilderness this weekend to do some trail clearing with Back Country Horsemen, and she is going to be my riding horse. Penny will pack! LT gets to stay home.
