How do you pass on a white bottom lip?

I LOVE the white bottom lip.

Just wondering how recessive it is.

My broody has a star/stripe/big snip and total white bottom lip.

Both of her babies by Wimbledon (who also has a white bottom lip) have the white lip.

  1. Is this a recessive marking that requires both parents to have the gene?
  2. Is it possible to get it from just one parent?
  3. When breeding two white lip parents will the resulting foal ALWAYS have a white lip?

that’s all!
thanks

All those white markings are due to sabino, splash, frame, or dominant white. Of those, DW and Splash are the most likely to put white on the lip like that, but Sabino could as well.

1 - not recessive in the sense of genotype, but there’s far more to the phenotype (physical presentation) than whether it gets passed genetically or not
2 - yes
3 - no

You can have her tested for the Sabino gene.

Only for the Sabino1 gene, and testing negative for that doesn’t mean there isn’t any Sabino, as there are thought to be at least a few more of them that aren’t yet mapped.

The bottom-heavy face white is highly attributable to Splash, and there are 3 new tests for what SW1, SW2, SW3 :slight_smile: It’s a single test, they just test for all 3.

Mare has a full bottom white/pink lip.

Filly has jagged bits of pink on the lower lip. Jagged would be more indicative of sabino then? Since it is splash that tends to smooth out lines?

Splash likes smooth lines.

Sabino likes the more ragged look.

The problem is when you have both. So, if you see something with jagged edges, that doesn’t necessarily mean it’s ONLY Sabino. For example, you might see a stocking that has a fairly flat top, but with a jagged look to the line. That would be indicative of both. That same flat top might be very smooth-edged, which would much more greatly indicate just Splash

Sabino also likes to keep white off the eyes, so if you see a horse with lots of white on the face but not around the eye, or around the eye but the eye has “eyeliner”, you’re likely looking at both :slight_smile:

My mare has it but neither her sire nor dam had it.

the yearling colt I have now is black with 3 stockings, large star, snip and white lower lip. Dam: solid black with 3 low white socks and 2 white hairs for a star. Her dam is a chomeless bay, sire is a sabino chestnut…so probably a sabino lurking in there. Sire is a Paint with sabino, splash and DW all in the pool!

My mare Stella has a white lip marking. One of her two colts had a lip marking. One of her two fillies has a full white lip with a big full blaze that gets wider as it goes down. She has 2 socks going mid way up the cannon on the left side. Both flat tops but the front one isn’t complete to the bottom if that makes sense. The mother, Stella, is definitely Sabino and has yet to not pass on nice face markings and some white on legs. But most are jagged stripes not big full blazes. I have another 2yo Warmblood filly out of a TB mare whose only markings were a few little white hairs on her face. She has a lip marking and jagged blaze, one full stocking, and one tiny bit of white on another foot. She is almost identical to a full TB brother she had except his white stocking was on a front leg.

I have my 4 girls all out in the same field. I call them the “blaze girls”. I’ve always wondered if Abba’s big blaze and white lower lip and chin were splash but I don’t think she has enough markings. But it’s nice to look at but doesn’t really mean anything in the grand scheme of thibgs. FWIW, the mare also threw my metallic coat mare Heidi. She has always thrown colors that are good examples of the color if you know what I mean. The metallic chestnut is a really red nice chestnut. Not washy. Abba is a very red light red bay, awesome black dappled at the moment! Then there was another darker bright red bay. And then the mare has thrown her color twice which I think is a brown bay but not dark brown if that makes sense.

Answer: come to my house! All of mine have a white bottom lip, even the grey had it and passed it to her filly. I’ve always thought it was just a fluke. Seems like I have horses with blazes that wrap around under their chins. :winkgrin:

Mine, too! Last year, I had fillies by a stallion who throws minimal white, and my mares are not blingy (one has no white socks, but a star, and the other just has 2 white hind coronets), yet I got 2 very blingy foals–one had a lightening bolt blaze, with a white nostril (I always mistake it for nasal discharge), white lower lip, 3 socks, and the other had a huge heart-shaped star, a snip, partial white lower lip, and 2 socks.

I definitely didn’t plan the white, but I do like it!

It’s never about “enough markings” :slight_smile: That’s the frustrating thing about these Overo markings - they can be as minimal as a little teeny star, to very loud, and everything in between, just depending on whether there are suppression factors going on, additional expression factors, a combination of multiple pattern genes, etc.

so yes, a horse who has a teeny star and zero other white marks can indeed be splash. Heck, a very solid horse with blue eyes not even a single white hair, can be Splash :slight_smile:

We just brought a Quaterback filly back from Germany in November and she has a big blaze, 3 high whites, and a white bottom lip. I believe that quite a few of his offspring do. Don’t know how it’s passed on, though…

A friend had a Consul gelding (out of a solid bay TB mare) that had a white bottom lip. From the Nimmerdor side maybe?
