My Horse Renny is close to having her baby! on Foal watch

[ZennaBug]

Strangely the had four BLACK clydesdales and one brown one, all studs 

there is still a chance she was bred to something else though, it could be a mule for all i know

my head hurts from all this thinking

I looked up equine genetics a little bit and with a (probable) pure black sire and a red dam, this baby can pretty much end up any color under the sun.  Unless I read the phenotypes wrong.

Provided there are no other hidden genes to dilute the foal (such as creme, champagne or dun), the foal will probably only be black, bay or chestnut if the sire is black.  It will not be grey, as grey will trump everything else that a horse carries.  Technically, black and chestnut are the two base colors that a horse can be, genetically, with black being E_ and chestnut being ee.  Your chestnut mare (provided she is genetically chestnut) will only be able to pass on a recessive allele, while a black sire could pass on either since his second allele is automatically masked by the dominant one that causes black.  The agouti gene (A) could be carried by your mare, as even a dominant agouti gene is unable to phenotypically affect the color of a red coat.  A black sire would NOT have a dominant agouti gene, as that would make him a bay. 

A black sire's genotype should be (A)EEaa or (B)Eeaa
A chestnut mare's genotype could be (1)eeAA, (2)eeAa or (3)eeaa
In scenario 1A, you will have a bay foal
In scenario 1B, you're looking at 50% chance of bay, 50% chance chestnut
In scenario 2A, you're looking at 50% chance of bay, 50% chance of black
In scenario 2B, you're looking at 25% bay, 25% black and 50% chestnut
In scenario 3A, you will have a black foal
In scenario 3B, you're looking at 50% chance of black, 50% chance chestnut

Sorry if you already knew the numbers... coat color genetics has always intrigued me and was my favorite part of genetics in college

Awesome!    I love genetics, but haven't read up much on horse coat colors.

So it sounds like this baby will be a solid color for the most part (bay coloring being the only option with 2 colors)?

I am so exited to see it! Hurry up mama and have that foal!

[rearing_palomino164]

Yay! I can't wait to see pictures of the foal!

UM, THIS IS AWESOME I love genetiiiics if I had passed chemistry I'd be a biologist right now...whoooo

[Aflame]

any sign yet???? xaflamex

[babylicketysplit]

nope nadda, just a bigger belly!

[ZennaBug]

Oh man, I wonder how big that foal is going to be...    Poor Renny, I bet she's ready for this to be done and over with lol.

[lovesbabysquirmy]

My my my!  *pokes head into stable*  Yuletide pony?  C'mon little one!  Your mama is getting restless I bet!

[babylicketysplit]

troll horse and troll baby! nothing, but the back area of her belly closer to her udder is more destended and fuller.   

[HavACrumpet452]

So exciting. I'd be more excited if it was a mule. There's a gorgeous buckskin mule on my local CL with zebra markings on the legs and a cross on its back. I've heard once you have a longears you never want a plain old horse again.

[Rainsong]

Any news?

[babylicketysplit]

no baby yet.  ugh.  but her belly is sooooo big poor girl. and shes cranky

[cyberunicorn]

could you not just give her a curry???? I think that is meant
 to work in humans anyhow 

(ps I know not to feed horses curry. for anyone that thinks i am serious)

[Aflame]

my be carrot curry xaflame

[Rhubarbpie]

Ooh will it be a Christmas foal?? Cannot wait to see pics xxxx
