Foal colours.

[B_2_B]

If mum is grey and dad is black what colours could the foal be?

Or is it more of a lucky dip if you don't know the specific breeding?

 

[Capriole]

what colour was the mum before she was grey?

 

[B_2_B]

Don't know that either I'm afraid!

I'm just wondering if my bet of a black filly is at all likely

You can have a play on here

but I'm pretty sure you would need to know mum's original colour or that of her sire and dam.

Ask over in the Breeding section, they will have a clearer idea as I get mixed up with anything other than the basic genetics of equine coat colour

Thanks
Would it be on her passport?

I think it'll make the stakes more interesting if there's a possibility of many colours

 

[Capriole]

this year we got a chestnut with a black sire, and a bay from a black dam lol

If you get a black filly I will hunt you down and glare at you

Depends when her passport was done and how quickly she greyed out

 

[B_2_B]

Hahaha

Ok will see if I can get a look at it tomorrow.

I reckon born bay or black to grey out.

As above, 50/50 chance of it greying out whatever colour it starts off.

 

[B_2_B]

Ok black filly seems a decent choice then

 

[a kind of magic]

Was just going to say there is a 50/50 chance of them greying out. Be interesting if you can find out the base colour of the mare, our foal this year from a grey mum (base liver chestnut) and a dark bay dad was a VERY bright bay, our grey mare's full brother is a bright chestnut so just goes to show it's pot luck!

I think grey is a dominant gene??
Snow Angel, I've got a jet black TB filly from a TB mare I rescued. Dam was black with white star. No idea what colour dad was!
My filly has no white at all.

 

[B_2_B]

Doesn't matter if it greys out we're just choosing a colour it'll be born as

<< me glaring at you

 

[maggiehorse]

i had a colt , mum was bay her sire was piebald colts father was chestnut and white as was his sire , guess what colour my colt was

 

[Waterborn]

Black filly from a bay sire out of a chestnut dam, Smokey black from the same sire out of a perlino mare. Quite surprised to see them both.

There should be some advice on Genetic predisposition .Try Sydney University or WBFSH meeting Seville 2011

 

[Cortez]

There are very few "rules" about colour genetics, but here are some: every grey must have at least one grey parent, but two grey parents will not necessarily produce a grey foal. Chestnut bred to chestnut will always produce chestnut. Horses can be genetically tested for colour (the genetics of which are complicated), and are either heterozygous or homozygous (sp?) and of course I can't remember which means colour is guarenteed or not!

 

[winkles]

That's one beautiful horse!

 

[rhino]

are either heterozygous or homozygous (sp?) and of course I can't remember which means colour is guarenteed or not!

Heterozygous - 2 different genes
Homozygous - 2 copies of same gene

So, for example, a homozygous coloured would always have coloured offspring

My lad is by a grey stallion out of a black mare. My guess was that he'd be born black and grey out.. i was right!

[foxy1]

I have a born black but greying out foal, chestnut Dam, grey Sire. I was still hoping he might stay black but the naughty foal won't play....

 

[velv]

I used the coat colour calculator for my foal this year out of a grey mare (bay base coat) and black stallion here were the results:

32.81% -Gray (Bay)
32.81% -Bay
10.94% -Gray (Black)
10.94% -Black
6.25% -Gray (Chestnut)
6.25% -Chestnut

I wanted a black filly but got a black colt! still v happy and at the moment no signs of greying out at 7months, fingers crossed he will stay black.
