Shep, you are Extremely lucky, please do not take this foal for granted. There was a 9% chance of survival and this little one was the rarity that lived

Shepp you're so lucky. <3

Could I have a slot? c: c:

May I ask why it's Dominant White? I'm a little confused since none of the parents are.. ;-;

[nimrod.]

The parents are both toveros, and overos/toveros when bred together result in the most likely chance of a dominant white foal. Which typically do not survive.

[Sezzas]

I've never heard that before >.> Where is information on this?

Cause like, as far as I'm concerned, Dominant White and Overo are two completely different things.

EDIT:
Okay, yeah, it's true that homozygous frame overos are pretty much all white with blue eyes like Dominant White. Still is different though x)
And it would realistically not be able to survive. But I'm guessing that's something you've decided yourself to do then? x3
I'm just making sure~

[♥ soft]

fun fact: not all overos are lethal white carriers c: to be lethal white the foal needs both parents to be carriers
you guys got me really interested so i went researching i hope this isn't rude D:
congrats on the cutie shep c:

[Sezzas]

Although, the overo gene is the lethal white mutation x) So if a horse is an overo, it is a heterozygous carrier x3

/I/ hope I don't come off as rude. I'm just a genetics nerd that can't handle not knowing stuff or being confused about it, I gotta know xD

The lethal whites that survive are extremely rare (because they are not lethals). Those very few that do are called Living Lethals. This however is a misuse of terms since lethal is, well, lethal. This foal had a high chance of becoming a lethal but didn't, It had a low chance of becoming a Dominate white, and did (Ww). Dominant whites and lethals fall into the same category of "Extreme Whites". Extremes typically come from mostly marked horses such as Overos or Tobianos. In simple terms, there markings (the white) have engulf the other colours. This is why we see Extremes in breeds like Paints or Appaloosas. Are Lethals and Dominant Extremes? Yes and no, it's like the question, is a square a rectangle and is a rectangle a square? Extremes is a colour term while Lethals and Doms are genetic terms. A horse can be a dom and an extreme but a extreme does not always have to be a dom. Now, how does all of this play into your question? This foal is a extreme of the Tovero, but through genetics he/she became a dom (since both parents have a white gene). Yes, both parents are Tovero but that does not make the foal a direct tovero (spitting image of the parents). Some things change.


Edit; I forgot to say that both Dom and lethals are mutations. Extremes are not mutations all the time. Also Lethals and Doms are not the same

Both of you guys are not rude at all! It's a good question!

i was reading this article about lethal whites if you'd like to have a read c: and here's the wiki on dominant white but my brain isn't computing this at 5am in the morning <3
HURRAY FOR LEARNING
oh thankgod, i love you guys and would never want to offend you <3 ^u^
EDIT: THIS WAS POSTED BEFORE I READ ANYTHING I'M READING NOW <3
EDIT2: this is very interesting, thankyou for sharing c:
