Saddlebreds were created through the breeding of Thoroughbreds and Pacers (Standardbreds) so that would be how it came to be present in the breed.

If the sire had it, since it's on the X chromosome, the filly would have one large heart gene and one "normal" heart gene. So 100% chance the filly would carry since the sire carried

That's the part getting my head all muddled... And for whatever reason that diagram made it worse for me LOL

Is there a really simple way of explaining how/when it is passed?

And is there anywhere that sources which horses have had the gene?

I was trying to look back through the pedigrees and realizing that all my ASB's tie to Eclipse (some stronger than others) but a long way back - I was kinda wondering if there was a known list of more current horses (just for curiosity's sake)

A sire carrying it will pass it to fillies 100% of the time.

A heterozygous mare (one copy) will pass it 50% of the time (to both colts and fillies), and a homozygous mare (two copies) will pass it to all offspring 100% of the time.

As for a list of possible carries, sorry I can't help you there.

The heart line in Quarter Horses
Because Quarter Horses long have been crossed with Thoroughbreds, the great heart line found its way into the sprinters years before AQHA was established. Today, Eclipse’s mighty heart is passed through sires such as:
A Classic Dash
Aforethought (TB)
Alamitos Bar
Azure Te (TB)
Beduino (TB)
Bugs Alive In 75
Calyx
Chicaro Bill
Chicks Beduino
Dash For Cash
Dash Thru Traffic
David Cox
Depth Charge (TB)
Diamond Charge
Dividend
Double Devil
Easy Jet
First Down Dash
Go Man Go
Hempen (TB)
Holland Ease
Jackstraw (TB)
Jet Smooth
Jonny Apollo
Lake Erie (TB)
Leo
Little Request (TB)
Merridoc
Mito Paint (TB)
Moolah Bux (TB)
Moon Deck
Pass ’Em Up (TB)
Piggin String (TB)
Raise Your Glass (TB)
Rare Bar
Rare Form
Rocket Wrangler
Ronas Ryon
Royal Quick Dash
Special Effort
Spotted Bull (TB)
Streakin Six
Takin On The Cash
Texas Dancer (TB)
The Signature
Three Bargains
Three Bars (TB)
Three Chicks
Three Oh’s
Tiny Charger
Top Deck (TB)

These are the sires listed in AQH and they would pass to their fillies only. If the sire was bred to a homozygous mare for the trait they would each pass a copy and all fillies would have two copies and all colts would have one (from the dam). If the original mare was heterozygous then all fillies would have one from the sire and there would a a 50% chance they would have two copies if they inherited from the dam. The colts would have a 50/50 chance of getting it from their dam and would not get it from their sire.

Too bad they don't list all the mares known to be homozygous.

So... A stallion carrier will always pass to daughters, but only to sons if bred to a mare who is a carrier (in which case the son inherits from his mother)?

Knowing which mares were homozygous would be handy.

I think that's exactly correct! And a list of homozygous mares would definitely be super handy. This whole thread has cleared up many of the confusions I had, I'm still wondering if anyone knows if there's any ways to find out if a horse has it other than ECG or necropsy? Since my gelding isn't a direct son of a confirmed horse, but rather the confirmed horses are I think a minimum of 3 generations back.
