Just curiosity really. I have a bay mare (sire-grey, dam-bay) who is in foal to a palomino, I saw last years crop of his foals from coloured and bay mares and every single one was palomino or palomino and white. I know that she has thrown one grey foal but don't know if the stallion she went to was also grey.

So is bay the dominant colour or would the fact that she has a grey parent make it more likely that she could throw something other than a bay?

Anybody into colour/genetics who could hazard a guess please? Thanks
 
its a bit like people. if the father has blue eyes and the mother has blue eyes, obviously the baby would have blue eyes. but if one parent had blue eyes and the other had brown, then the baby would have brown eyes.

if the father was grey, i'd say the bay would dominate.
 
oops, shows how much i know

dont enjoy biology, remembered the eye thing from year 7 lol now year 10

Her previous owner can't even remember when the mare was put in with the stallion! She was still running with him when I bought her last month. The stallion is a welshy type rescue pony that she just breeds with every year and she had no idea of his history when I asked her about him.
 
Oh goody, a tabby then!!!!

If your CB threw a coloured you'd KNOW she'd been playing away from home wouldn't you?

Well a palomino is the result of the chestnut gene and the cream gene working together. Your bay mare is not carrying the grey gene because that is dominant - if she had the grey gene she would BE grey. It is possible that your mare might be carrying a recessive chestnut gene that you don't know about.

So the foal could turn out to be bay, dun (if the bay and cream genes combine), chestnut or palomino. It definitely won't be grey, because one parent needs to be grey for that. It also won't be coloured, because one of the parents needs to be coloured.

I think that's about right from memory!

It depends if the gene in the father is homozygous or hetrozygous. Does the breeder know?

Homozygous and hetrozygous mean, what please? I often see coloured stallions advertised at stud as 100% one or the other, I know I can go and look this up but it's more interesting this way.

I know that a bay mare I had before had a chestnut gene (her dam was chestnut) as she always threw chestnut foals to bay stallions.

SSM Thanks for the link, and Donkey would probably enjoy having her bottom smacked!
 
If he is a purebred he is very very mismarked!!!!!!!!!!!!

Think it's a skull and crossbones on his bum!!!!!!

PS Donkey gets her botty smacked regularly - very gently when I tell her what a beautiful bum she has

Surely a horse can throw any colours horse aslong as in its past genes. Talking human wise i'm blonde, blue eye, and nothing like any of my parents. If i went back in the tree there are blondes, and blues eyes. I though we could carry genes without having them ourselves?

Homozygous: When two genes are identical, for this discussion the individual has two tobiano genes. Example- Homozygous Tobianos will always pass a tobiano gene to an offspring (genes TT).

Heterozygous: When genes at the same location are not the same- and the parent can pass either gene (genes Tt). An Example- a tobiano foal with one tobiano parent and one quarter horse parent can only have one tobiano gene, regardless of any external markings!

If you replace said tobaino with palomino paint, there you go!
Am a horse colour geek, sorry for jumping in this post!
 
There's only room enough for two different types (alleles) on each gene for each thing, so you can have brown hair and carry the gene for blonde. Which one shows depends on which is dominant. So if a bay horse is not chestnut and has a chestnut a few generations back, and then gets put to a chestnut stallion and throws a chestnut foal, that shows that the mare has the recessive chestnut gene as well as the one that shows her bay colour.
I think that's right... it's much more complicated than that though, it's not just one gene controlling the colour, it's a couple or few!
ETS: hmm, re-reading that I may have got mixed up on the first bit, but don't have time to research and change it sorry!
 
Thankyou all. I am now going to bimble off to colorfoal.com for a look there. I also have an overo paint mare that will be looking for a husband in the summer, so I'll see what I can find there about her too.
 
Good grief! Can't they just stick to a few basic colours?

I mean, a bay is dark, light or bright as far as I'm concerned, and what does Champagne translate into English as? Very interesting, now I'm trying to work out whether Robin is a splashed white overo or something else, all down to if her legs are coloured or not........hmmm. far easier if she were a cow, she'd be a hereford no problems! Poor girl, I like her really!

Ok, this is my specialist subject!

Firstly, unless one of the parents is grey, the grey gene will not be passed on.

A bay put to a palomino can produce either a buckskin, bay, palomino, chestnut, smokey black or black. You have a 50/50 chance of the foal being solid coloured or diluted.

When is she due to foal? (I'm very excited, want to know what she has!).

Oh Lord! It IS going to be tabby! I have absolutely no idea when she is due to foal, she's certainly in foal because it kicked me this morning. Seller thought that she MAY have gone in with the stallion in May, but it could have been June! Oh helpful! It will just be a waiting game then. I'm quite looking forwards to it as usually I have some idea what the foal will be like but this is going to be a complete surprise. Ah well, as long as they are both healthy. I was going to put her pedigree up but can't get the link through. She's on www.allbreedpedigree.com Baikala Bey, loads of grey in her lines.
 
Ditto this but I've always heard the term as "dilute" gene but I think you are most likely to end up with a bay or a dun.

You did see what we got????

Mum - Bay (both her parents bay)

Dad - almost black but technically dark dun (though his Welsh passport says bay...)

and we got...

Though at least this is the gorgeous summer colour...

Hee hee!!!!

At least with Asti being a ginge and therefore gg, her mum was ginge and gg, dad was grey Gg - if I go to a chestnut I get a guaranteed chestnut, a pally would be 50-50 pally or ginge and I'd only get a grey IF she went to a grey. Oh and a cremello would guarantee a pally.

Probably haven't helped really but it is really, really interesting all this colour genetics...
 
Wow! What a fab summer coat Ivy (it is Ivy isn't it?) has! I bet you had a heck of a shock when she arrived!

When she was born, my sister wussed out of getting mucky and was at Byters head, video camera in hand, and I was the midwife...

Had a minor panic as only one hoof was out, but the mare got up, and as she laid back down the other hoof popped out. As I guided the foal out (yes, the Evil-Ivy!!) all I could see through the sac was a kind of ginger colour, so thought we had a chestnut... However, swiftly realised that it must have just been blood/fluid making it look that way.

We were really shocked to see this pale cream almost white... well... kangaroo really... she had pink skin round her nose and eyes, and blue eyes. We really thought she was going to be a cremello!

But then within hours her skin started to darken

THEN she loooked like she was going to go dun as her legs went really dark...

So now she's cream in winter (well with green and brown patches covering most of her, filthy oik) and a nice pally in the summer.

Edited cos my spelling is cak!
 
I'm still waiting for my parcel to arrive!

I'm sure she would have fitted in with my christmas card (thankyou!) if you had tried hard enough!

She is absolutely gorgeous - just let me know when you are sending her to me please!
