Guessing colour of foal ??

[Victoria25]

I know this had been done to death but wondered if someone with amazing ‘knowledge’ could help me?

We are due a foal in April (touch wood) and just having a guess at what colour he/she will be. I really don’t care either way and Im guessing it will be a grey (eventually).

My Mare is grey (born chestnut) and we have put her with a black stallion

My mares sire/dam both grey
Stallions sire chestnut with his dam dark bay/brown

I dont know anything about coat genetics, but can guess grey.

My 2011 filly was born chestnut and is turning grey.

Her dam is dark bay/black and the sire is grey. Dams sire was chestnut

So similar to yours just the other way around !

This will take a lot of the guessing out of it...

Though if your mare is homozygous grey (which she may be with two grey parents) she will only be able to produce grey foals. If not, there are other options too.

It will be born either bay, black or chestnut (I think its equal probability for all three) but as said, will turn grey regardless. You must be so excited! Good luck!

Im not sure if she is - both of her parents are grey.

Her dam's parents were both grey
Her sire's parents were grey (dam) and bay (sire)

If a bay is thrown in somewhere does that make a difference?

I really dont care what we get - just so excited and should be a 'different' cross

Not really — grey is not a colour in its self, it is a modifier that means the colour fades from the coat, which is why foals are not born grey.
Grey is also dominant, so a horse carrying just one copy of the grey gene will always turn grey, but will only have a 50% chance of passing that modifying gene on to offspring.
