I don't know. There are several gene combos that make a similar color.

This is an awesome horse to use to showcase just how similar some of the phenotypes overlap even though the genetics can be wildly different! I had a breeding project similar to this horse at the beginning of Mesa so the guess is based on that grouping but that white spotting is tricky. Good luck everyone!

Phenotype- White-spotted silver brown roan pearl appaloosa
Pigment Modifiers- E/E A*/A* prl/prl Z/z _/TE1
White Markings- R/W3 LP/_
White Factor- I keep going back and forth between light and minimal. I am leaning light for this contest but could also be convinced of minimal since the stockings aren't showing that characteristic patterning of w3 but that blaze has me thinking light. Going with light for now :)

@TheBlueMoors I didn’t even think of W3 even though I breed for it! Now I see that it really does look similar to a lower white factor W3!

Am I allowed to edit my guess? I withdrawal my entry as I accidentally found the horse.

Yeah I think the white spotting is either w3 or lp with no expression. I don’t know how to tell the difference. I didn’t find the exact horse, but I found two exceptionally close, and seeing their genes didn’t clear that up for me. I think the coolest part about the horse LG picked is that there are many ways to arrive at this point, from every base color.

I’m curious about BlueMoors brown call, because I didn’t think just EE AA would be dark enough to get to brown? Is there a sty or Dp missing or am I about to learn a new thing? (I do think brown is a likely starting color but do those genes make brown? How?)

@SummerMonarch, LP is Appaloosa characteristics- white sclera, striped hooves, speckled skin around soft points, and frosting on body. It can be very prominent across the entire body or just concentrated in a certain spot or just look like ticking through out. The LP should be considered separate from any white spotting present here- that is how I determine presence of LP and whether or not it is acting in conjunction with PATN1/2 and/or if there are any other spotting genes present.

Each white spotting gene has its own characteristic patterning and is more obvious on the loudly marked ones versus the ones who have no white factor up to minimal/moderate. This is a tough one because the horse is not loudly colored so there is some overlap in the different phenotypes of white spotting but a few can be ruled out straight away based on their behaviors. Sabino is pointy, tobiano likes leg white and withers, w1/w2 are “moldy”, w10 is splashy with lace, w20 by itself is very very minimal effect, blah blah I can go on but I won’t bore with details.

Great question about brown- under the new rules, in order to be brown the horse must have certain combos- specific combo of darkening genes in conjunction with at least one dominant extension and 1 dominant agouti. The clue lies in this horse’s paleness- obviously has some dilution genes present but also obviously does not have any darkening genes (or enough to count). By deduction, the horse will be either A*a or A*A* which is still present in the game in certain lines of horses and will give the phenotype/genotype brown regardless because E_A*a (or A*A*) IS brown.

A* is the notation for brown versus just A or a which is dominant agouti or recessive agouti.

With the new brown inheritance system, the horse will be any combo of E_ A_ with any combo of the darkening genes sooty, sooty plus, and/or DP but again looking at the pale washed out color, that is not the case here.

I used to breed brown based pearls with most of the dilution genes (silver and champagne specifically), so that’s how I’m picking that base to build the rest of my guess off.

This is cream on chestnut, yeah?

And this cream on chestnut with darkening genes?

Wow you are cool. The first one was a chestnut with single cream, single sooty, single TO. The second was a bay, hom cream, hom sooty.

Every time we do one of these I learn something. I didn’t know you could get the same genotypes from different phenotypes. But, using the onion analogy, it makes a lot of sense.

(I’m about 80% sure I got the bay/chestnut correct. Big margin for error.)

Curious if anyone has gotten the correct answer yet? This was a hard one!

Holy moly I was CLOSE with that genotype. Just some switched-around alleles and some missing alleles. I missed satin, pangere, and snowflake which makes sense since these genes "hide" in heterozygous form...

And minimal white factor! Doh I should have gone with my gut feeling.

Wow I was not expecting that at all though. I felt like I was guessing well because the pony was so close in phenotype with my silver brown pearls but it could have easily been something else.

Thank you! I'm going to contact you by PM LG!

thank you so much!
