Eye Coloration (not sure if this is under the right forum)

[Livinwright Farm]

We have been studying our beloved new little Olivia, and have noticed her interesting(I believe unique) eye coloration. Both of her eyes are like this: golden brown outer ring, inner blue/grey ring, then her pupil. A picture can be found Here ... I hope to have a better pic up later today.
I was told that it isn't possible for 2 brown eyed goats to produce a blue eyed kid... Granted, Olivia isn't BLUE eyed... or IS she???
In all of this wondering, I am keeping in mind that it might have something to due with her being the product of an accidental inbreeding... like a genetic fluke?

Oh What?!?!? I just found this site ( http://www.goatspots.com/blueeyes.html ) explaining blue eyes in goats, and am SOOOO excited to announce that Olivia is considered as genetically blue-eyed and will be able to produce completely blue eyed offspring!!! "YES!!!!!!"
Apparently either Maude & Momma's sire or dam, or Marly's sire or grand sire or grand dam was blue eyed and it just skipped 1-2 generations!! This is AWESOME news!!!

Pretty girl! How fun. And yes, post more pics!

Those are "baby blues" as in, they will change to brown or amber as she ages.

Blue eyes are bright, sky blue at birth.

taken from the site I mentioned, "some goats have eyes in which only part of the iris is blue(this also occurs in dogs.) Such animals are most likely heterozygous blue eyed and are considered genetically blue-eyed, even if only the tiniest portion of the iris is blue and they can still have offspring with completely blue eyes."

Also, earlier on the page they mention that "blue eyes are considered a dominant trait, though it has been known to skip a generation or two and pop up later on when two brown eyed parents are bred together".

We will keep a photo record of her eyes to see if there are any changes in the coloration. Who knows, she might just keep the blue. If so, then I am guessing that it is due to the inbreeding.

Pleasant finding!
Every little thing like this one, it's like a ray of sunshine on a rainy day
You deserved many more of these happy rays!

What I'm trying to tell you is...that isn't BLUE. Have you ever noticed how newborns of several species are often born with grey-blue eyes that change later? That's what you have.

I also don't believe blue eyes skip generations. One parent must be blue eyed (it's a dominant trait, so if they HAVE the gene, it is expressed - if its not expressed, they don't HAVE it).

They're going to be amber or brown.

I am honestly confused by your reply.
For those reading this thread, I am not trying to bicker, just looking for the most clarification on genetics I can get.

What happened to homozygous recessive(Bb vs. BB or bb), which for whatever reason makes a dominant trait recessive? Which is mentioned on the site I mentioned in my second post on this thread.(they refer to it as heterozygous in terms of goats, but in people it is referred to as homozygous recessive)

I know it can make your head spin..but...

There is no 'recessive' in blue eyed goats. They can be heterozygous (ie have ONE copy) or homozygous (ie have 2 copies) but BOTH will result in the goat having blue eyes (it's dominant).

Sooo

If your goat is brown eyed...it does not have the gene for blue eyes. It cannot have blue eyed offspring unless bred to a blue eyed goat.

That site is mistaken when it says blue eyes can 'skip' a generation. More likely is that one of the parents was marble eyed, and it was not noticed. For instance, my buck D Lux is marble eyed. When he was born, they were ice blue with a brown outter ring. As he aged, that outer ring became wider, so now you can only see his ice blue in the sun (when pupils are fully contracted). Marble eyes are genetically full blue...but it's hard to TELL now that he's a yearling unless you see him outside in the sun or shine a flashlight in his eyes.

Still, the color difference in your doeling and a true blue or marbled eye is obvious to the trained eye...hers are not true blue. I suspect that she will have amber (gold) eyes later, often amber eyed goats are born with that grey-blue color.

I have a Boer x kiko kid w/ eyes that color...safe bet neither of her parents were blue eyed.

I don't mean to burst your bubble, but I gotta go w/ Kate on this one.

Adorable baby, though.
