AQHA mare: Carolina On Sunday

APHA stallion: Bold Kiss

It's still early (due May 3rd), but I wanted to start a thread so I could keep track of her belly and habits pre-foaling. Also, what color/gender do you expect? :) Can't wait to see all the new babies next year, feel free to post yours and compare!

Pictures are of pre-pregnancy and then current (7 months)

Pedigrees-

Hers: Blackwell Cat Chex; Settle It On Sunday
His: Smooch; Bold Win

*Kiss is homozygous for tobiano*

Thankyou I am incredibly excited! Sorry about the picture attack, I wanted to update her growth and boy has she grown already :). Here she is at day 237 I believe, nail test says a colt (twice) so far so will be exciting to see if the prediction is correct!

**Note: That cute little boy running out to her is my son (I wasn't far from him like it seems in the pic, my phone makes the picture distant. He is NEVER unsupervised or allowed to approach the horses without someone holding him) and that's his English whom he calls Moo because she has spots like a cow :wink:. He is 1 1/2 and he LOVES his horses!

She isn't thin at all trust me, it may be my amateur picture taking. I just had my vet out last week (one of my mares has thrush) and he told me that he thinks she may be getting too much and to watch her weight gain. He was her previous owner so he knows her better than I, she is a piggy. And that would be neat if she were a BAB as I've always wanted one, but she doesn't change in her coat like you explained, she gets a little darker in winter, then sheds back to the bay. She doesn't get red or black, but is that a rule? He looks better in person I assure you , he is bleached out in those pictures, but a bay foal would be nice! Anything, but chestnut. Not that I don't like chestnut (I have 3) a healthy foal is all I need. :)

Each brown is unique, some with huge color changes and some with very little. Your mare is a brown and so is the stallion. The lighter areas are on his soft spots like every other brown. Areas that you would not expect to see sun bleaching.

(forgive picture size)
A sun bleached black, notice that the soft spots remain dark. In the winter, she is as black as night, no light areas on her entire body, only sun damage to her mane.


As far as getting a chestnut, you have a 25% chance of chestnut, 75% chance of a black based foal, 25% of no agouti passed on, 75% chance of receiving agouti. Odds are in your favor to have a brown baby. But brown is a master of disguise and it will be obvious with the first winter coat :wink:

I didn't know any of that. I figured I would have a bay/white either way because when he's bred to a black he throws black, when bred to a bay he throws bay or black (mostly bay), and to a chestnut, he throws chestnut or black. I've seen a lot of his foals. He looks similar to my dna typed black and white so that with his progeny results is what sold it for me, but I wasn't worried about his color, i was focused on his temperament and body. Her mother produced sorrel mostly, even when bred to a black tobiano she got that sorrel. my mare was the oddball. I'm not sure from her father. She is being DNA typed so will be neat to see her results. If I already have a brown I guess I won't need another one :wink: though I've heard browns can't produce bay and only produce liver chestnut or standard sorrel?

Brown is a black based At agouti carrier, if a horse is At/a and is bred to a horse with the dominant bay agouti, you could still get a bay when the black gene is also passed on. As far as liver chestnut and sorrel, they are genetically the same, red based and agouti has no effect on red based horses.

As far as what a horse produces (color wise), one parent only gives half of the color genetics for the resulting foal. Your mare's dam is listed as chestnut on allbreed, she can only pass red genes, the stallion gives one as well and a heterogyzous black based stallion has a 50% chance to throw the black. As an example, my mom's stallion is EE aa, and every grey mare he has bred so far has produced a bay or brown foal that didn't grey. He only gave the foal an E and an a, the mares were heterozygous grey and didn't pass on the grey but did pass on an agouti. Progeny reports can tell you very little unless you also consider the other side of the family tree :wink:

Actually as the stallion owner has indicated that he is homozygous for black (EE) the chance of a chestnut foal is zero. But he can still be a brown (AtAt or Ata) and homozygous at the E loci for Black. However what you just said above "when bred to chestnut he throws either chestnut or black" means he is NOT homozygous for black, as it takes two ee to get a chestnut foal, so he has to be passing one of them, and thus would be heterozygous Ee and then your chance of a red foal would be 25% as your mare is also Ee (her dam was a sorrel right?). If he were truly homozygous for black, as the owner is advertising, he should never, ever produce a red foal, no matter what color he is bred to.

I looked at so may studs lol I was trying to find the right ones and grabbed Rosie's file, I figured this out looking at her parents lol oops wrong mare. Thankyou, I personally love browns and she is my favorite of all the colors :). Okay so I'm confused because he does throw chestnut to palomino and chestnuts? So he MUST be Ee correct?

Thankyou, I don't care what color he is honestly, but its nice to know what I can get :). How is his daughter? I really loved his personality he is so mellow and sweet.
THANKYOU, that makes much more sense :). ^^ her dam is black, her sire sorrel. My vet owned the dam before she passed when foaling her last filly.

According to the color coat calculator you, the percentages are 58.25% brown, 25% chestnut, and 18.75% black. Since you will get a brown with either AtAt, or Ata it is a higher percentage than black since you only get black if you get aa.

I know it is all a bit confusing!

You can play with the color calculator at http://www.animalgenetics.us/CCalculator2.asp. They don't have brown on there, but you can use bay.
