How can this horse be this colour?

Here's a link to a youngster for sale on AdHorse UK. He's a nice looking boy which is why I read the ad.

Now apparently he is by an Irish Draught sire our of a Welsh D/TB cross. As far as I know, there are no coloured horses allowed in any of those 3 breeds. So how can this youngster be a skewbald?

I wondered if any of the splash markings which are allowed in Welsh Ds could have sort of combined, but it doesn't seem very likely.

Am I missing something?

No idea! Pretty boy though.

Welsh breeds can have splashed white overo, recessive gene I think.
Sabino Overo is in some Welsh types.

So it's possible they got a surprise when the coloured popped out.

Chev's your man for this one, what she don;t know about colour genetics......

@chev any ideas?

Or did a bit of Irish cob sneak in there somehow?

Splash white does occur in the Welsh breeds and can result in some very loud coloured markings but that's not splash. I'd question the breeding to be honest. Something's crept in there for sure.

Edit to add those are classic tobiano marking which definitely don't occur in those breeds.

I didn't know you had part bred ID classes.
I wonder why they are for sale as they (I guess) chose to breed them.

Thank you @chev ! I've noticed this a fair bit recently - I think horses with Irish ancestry sometimes have *hem hem* uncertain breeding...

I wonder what would happen if I asked the seller how he came to be that colour?!

Could it be that there is genuinely something else in there - I have heard of horses referred to as 'Welsh' when they are technically part bred Welsh, but it seems to be ok to do this. I know the breeding is on the advert, but it means nothing to me.

The damsire is a tb crossed with something of unkown parentage registered as an irish sport horse. The dam dam a proper welsh cob. So the colour comes from the 'something else'!!

 

[Jane&Ziggy]

Ah ha! There had to be an X in there somewhere!

Thank you @eml
