Dear Chev!!!
Your so good its inspiring!!!
I have a blue roan, but in the winter his points - face and legs are black, as is his mane and tail, but in the spring his head and legs go chocolate, but his tail and mane remain black.
So what is this?
And also, you say that with roans one of the parents had to be a roan, are there any particular breeds which predominanetly are roans?
My boy is 16hh, very long back, and big bone with small piggy eyes.
Have no details of his parents, but he was born in France and he looks like a freisan crossed with a heavy french breed to me, but with a long back!!!
Any ideas would be very gratefully received.

The Ardennes, the Brabant and the Breton all carry roan and roan examples are commonly seen. They are all heavy draught horses and could well be part of your lad's makeup.

He sounds like a roan; roans can vary according to season but the changes are the same each year (that is they don't get progressively lighter as greys do).

Cheers!!

I've managed to find out his dam, Black Bess of Croust was grey and his sire, Romany Kajun was Piebald.

Also discovered his Grandsire was a world champion, and 3 times european miniature champion as well!! It appears the star quality got lost in the process of my lad's making!!! :D:D

so what about a black pony ( 3 white socks and blaze) with white splashes on her belly underneath? oh and she has a white splodge just below her knee on the leg without a sock
is that just classed as black? :cool:

Sounds like black with sabino. Sabino causes long, ragged socks, bottom heavy blazes and belly splashes. It can also cause roaning and odd white markings on legs without socks. She sounds typical :)

Thankyou Chev, will look them up and let you know if I think any of them could be in his bloodlines!!!
Thankyou Thankyou Thankyou!!! :)

Why is my horse going grey??

Hi just wondering if anyone can help me??? My coming 7 year old Dutch WB gelding has been developing these random white "splotches" on both shoulders since October 2008, and is getting more and more "roanie" every day! His sire is grey, and I believe his dam is bay, like he is. He has 2 other full siblings, 1 older gelding that is grey, and a younger mare, also grey.
Thanks for any information you might have!

The passport for my filly has just arrived & it says she is a BLACK TOBIANO. :confused:

I put down she is a skewbald (tri-coloured) though the vet thought pie bald as a young foal but she is def skewbald now!

Her sire is a bay, the dam is a TOBIANO on paper but looks like a liver skewbald to be.

Having read this thread, does this mean that if my filly was to ever have a foal, the foal would be coloured? even say with a black horse???

Is it such a strong gene?

Thanx.

so what would scarlet come under?

She's chestnut with sabino :)

Tobiano is teh correct term for a horse carrying that gene. It causes the patches of colour as on your mare. Piebald and skewbaled are commonly accepted terms but the correct term is tobiano.

Her sire is a bay, the dam is a TOBIANO on paper but looks like a liver skewbald to be.

A liver skewbald would be classed as liver chestnut tobiano.

Is it such a strong gene?

Thanx.

It's not a case of being a 'strong' gene. A gene is either dominant or recessive - tobiano happens to be dominant. That means that a horse carrying even just one copy will express the pattern - that is, they'll have splodges.

Your mare has only one copy. That is known as heterozygous. Two copies is known as homozygous.

Your exact chances are - your mare x heterozygous coloured stallion; 25% chance homozygous coloured foal; 25% solid, 50% coloured (heterozygous)

Youe mare x homozygous coloured stallion - 50% heterozygous coloured, 50% homozygous coloured.

Your mare x solid stallion - 50% solid, 50% coloured (heterozygous)

Ok thanx that was really helpful, i'd never heard of Tobiano & would never know just by looking. :) I wondered if a Tobiano horse is something many owners would rather not have!

My mare is mild Rabicano bay. Has the odd fleck of white hair at the base of her tail, white chin, white legs and mild speckling of white hair on her barrel and flank.

Did you have chance to discover anything futher about my boys unique marking Chev?

After reading as much as I can find I'm thinking it may be releated to a syndrome seen in some greys called bloody shoulder. It's an area of coat that doesn't grey out, and although it's called bloody shoulder it doesn't neccessarily occur just on the shoulder. It usually happens in fleabitten greys and especially Arabians, but I can't find any other way to explain your lad's marking!

You can see bloody shoulder marks here (scroll down the page). Funny, I posted this link on another thread earlier tonight - they have some really interesting horses...

Hi, what would you say about my boy's colouring?
He has what I think are the homozygous ink spots down his hairline right in the middle of his mane.
There are 2 mares (same colour chestnut as him) in foal to him at the mo...what colour do you think they might produce?
