Snowflake Expression?
-
So if you breed a hom snowflake stud to a presumably "normal" appaloosa mare (no snowflake), is the foal always het? Is it just a basic punnet square? How does snowflake get passed on? Does het show snowflake? Or only hom?
I'm considering buying snowflake since it's available today, but I want to know exactly how it works first. If I did buy it, where should I put it? I have a foundation stud who is hom snowflake, so should I get another stud or should I get a mare? Would it be better to add snowflake to one of his babies? Of the many I have bred from him, only ONE ended up presenting snowflake, and the mom wasn't even appaloosa. Here's his link, so maybe someone can explain it. Could the mom have been het snowflake even without being appaloosa?

Thanks! -
The dam carried a snowflake gene. You can find it on regular creates, but it's like any other gene, they are very random. I think putting it on another stud would be better if you have the patience to wait for hom snowflakes to appear in later generations. Two studs would be better for the line later.Thanked by 1newmag1659

Thanks! Should I put it on a foundation stud or a second gen? Should I get it hom? Or, I could put it on one of his sons, and have to add only one copy assuming they're het. What do you think? -
In answer to your original question. If you cross a homozygous snowflake with a 'normal' horse, then you will always get a heterozygous snowflake (basic punnet square). Het does not express so you won't see it on the coat colour. Homozygous will show, but only if there is at least one copy of appaloosa.
Crossing homo (two copies) with het (one copy) gives you a 50% chance of hom and 50% chance of het.
Crossing two het gives you 25% chance of hom, 50% chance of het and 25% chance of none.
I hope this explanation helps you to decide. -
To show snowflake, you need hom Snow and at least het App. So this colt got the App and one Snow from his sire and the other Snow from his dam, who is a lucky create that got snow! She is almost certainly het snowflake, not hom, but technically we don't know because she's not App and wouldn't show it even if she was hom. It's a random but rare gene, so she could have two but it's highly unlikely.
So yes, it's a basic punnet square, with snowflake being recessive and only showing when homozygous.
Appaloosa is a separate gene completely and inheritance of the two are not linked. However you need it to see snowflake.
All of those babies you produced from this guy are guaranteed to be het Snow, since he's hom. What I'd recommend (and what I'm doing with my own Snow line) is to keep the best couple colts who have App and keep all the fillies that meet your quality requirements, whatever those are, and then breed them to each other (inbreeding doesn't have any effects in the game, so breeding siblings is fine). You should start getting snows in that third generation. Also you'll start getting tiger eyes, since the foundation stud of the line is a TAoLMP.
Personally I'd use Are We Here Yet as your main Gen 2 stud since he's hom, so his babies with het mares will have a fifty fifty chance of being Snow and will be guaranteed carriers, vs. breeding two hets, which will give you half snow carriers, 25% snows, and 25% no snow at all.
Also, with a lined (non foundation) horse you can only GMT on a gene that the parent could have given it and it missed. And the Roving Gene Sales only work on foundations. So you can't GMT another snow onto his babies and make them hom unless the mother carried it, and actually I don't think Snow is in the GMT lab so you can't even then. You can only put it on foundations with no living descendants. So you can't add it to his sons, sorry.
You can definitely develope a snow line starting from just one homozygous stud, but multiple stallions means you can breed more mares each season, so that's what I'd do if you want to buy it.
And last thing! If you go to the upgrade page and choose a horse like you're going to buy Snow for it and click "modify this horse", it'll show you which genes it has already. You can find het snows that way. But you can only pull up horses you could mod, so it only works on those foundations with no living descendants I mentioned.
Thank you for coming to my seminar lolPost edited by Taliesin at 2019-06-13 13:32:05Spiderweb Stables

On the other hand, hopefully snowflake foundation mares would give you a few more nice hom gen 2 colts like this one to work with, so that's an idea.
What I did last time snow came up was check every single horse I could and I added one gene to each of the two het mares I found, so now I have two foundie Snow mares. And I made another stud. Or two. So that's an option for you tooPost edited by Taliesin at 2019-06-13 13:54:46Spiderweb Stables
