Different Breeds of Guinea Pigs (A Breeders view)

Now don't foget the part where I am completely genetics illiterate, especially with guinea pig genetics.

Did I understand correctly that the eye color comes from the same genes as the different hair colors or are they a completely different set of genes at work?

Where did Snowangel and Cuddler's blue eyes come from? Snowangel is all white and Cuddler is orange and white. Were they "suppose" to be black eyes but something "went wrong"? Most of my babies have black eyes, two have the pink eyes, Cocoa (lilac?) and Joey (white, cream and a seemingly very light lilac?) and of course two have blue eyes.

Salana, great explanation. Love it. Love piggy genetics. E, yes, the relationship between silver and golden agouti is very cool. I used to teach middle school genetics, and my pigs are definitely coming to school for the genetics unit next time I teach it.

I don't think anyone knows where the blue eyes come from. Or where Suzi's blue sclera (the whites of her eyes) come from.

Now, I'm sure you've already done this salana, but does Suzi have any problems with her bones or with urinary calcium? Pubmed shows "blue sclera" to be associated strongly with the disease Osteogenesis Imperfecta in humans. I was just curious, had to check!

Hi guys, sorry I've been MIA. I've been on vacation/camping/not around Internet. And I just switched jobs, so that's why my e-mail bounced back. I'll change it right now.

Based on Josephine's description, I think Wishes is a dilute agouti, though he has brownish/greenish hazel eyes; they're definitely not pink. I think he falls into the "beige" category of color. His belly band is a light cream color.

Most of my pictures of him can be found on this page: http://www.pbase.com/dellybean/guinea_pig

Here's a closeup of his eye when he was tiny: http://www.pbase.com/dellybean/image/73781255

You're welcome to use any pictures of him you'd like, Josephine.

Suzi has had small amounts of bladder calcium. It's interesting about the blue sclera being associated with bone problems. Mice with Einy-like problems and busted tfe3 genes on top of that, have terrible bone problems. Of course they found that out by breeding all these problems into the mice.

Maremma-

Yes and no.

There is a Pink eye gene. That determines whether the pig has dark eyes (brown, grey, etc) or light eyes (pink). That Pink eye gene also has an effect on the dolution of colors.

For example, a pig that his red all over and has dark eyes will just be a self red. A pig that's red all over but who has pink eyes will be slightly different. The pink eye gene will dilute the red color to a more orange tint. That pig will be called a self orange.

And then there is the ruby eyes, which are dark but turn reddish in the light. When a pig has chocolate hair, his eyes are always ruby. That's also true for other colors.

So hair color and eye color really depend on one another.

That explains Widget's eyes!

Edwin is shiny but I don't think he's a satin. Kaomi looks tiny, too tiny to be away from mom. I hope your friend isn't breeding them?

This was a younger kaomi's pic!I decided to post this one because of her blue eye!:-)

This pic has been taken in a shelter!She is an adopted guinea pig!

Edwin is neutered! We are against breeding.

Wonderful Briciolona. I knew YOU were against breeding but you never know about other people. :-)

Briciolona, Abby is adorable! I have to admit, a few of those pics of her look like a toupee sitting on a table waiting for the bald head it belongs to. hahahaha!!!

Finally ready to start finding some Marked pigs. I know there are TONS of Broken Colored pigs out there, so I'll look for a variety of combinations to use.

I still would love to have a Beige, Tan, Golden Solid, Dilute Solid, and Brindle (from the other groups) if anyone can dig one up.

So, submit pics for:
Broken Color
Dutch (I need appropriate markings)
Himalayan
Dalmation
Tortoiseshell
Tortoiseshell and White

Here are the pics so far:
Reference Thread

On the Marked pigs, it would be nice to find some checkerboard pigs. Side, top, and belly views are all appreciated.

I have a broken silver agouti (or would he be dutch?) If you would like to use him, I can take another of him, where he is not pretending to be a knick-nack!
