    Can Siamese start as hooded?
    AKA Cuteness alert!

    Will they molt their hoods off and become solid Siamese?
    I am picking one of these boys up from a friend to add to my colony. Just wanted to know exactly what they could be as she doesn't have any visible Siamese in her colony and she referred to them as "the dirty nosed babies that pop up every once in a while."

    It's not really a hood, it just looks like it.
    Siamese are notorious for having really strong molts. Some will start off a solid point colour, and molt into base colour. Yours there are perfectly average molting siamese, the smudges will disapear in a few weeks or so. :)

    Words can not express my excitement right now. But dancing banana can! :banana:

    Edit: I thought Siamese were co-dom? Need one to make one?

    No, siamese is recessive.

    They are too cute for words.

    Congrats.

    Ok well for some reason I thought it was co-dom.
    Thanks! I will get more pictures of them when I get them tomorrow.

    Siamese are recessive and can start life off as hooded.
    It's a hooded Siamese, or Triamese or marked Siamese take your pick.

    Very cool, learn something every day. I guess Rex is the only dominant mutation then out of the more common ones?

    Not the only, but the most common besides dominate the high white gene.

    The weird part about rex's being dominate is that typically a dom X dom breeding would yield 3/4 dominate and 1/4 standard coat.

    Rex X standard coat acts like a dominate trait in that half the kits will be rex and half will be standard coats(by odds).

    Rex X Rex acts more like a co-dominate trait Rex X Rex = 25% double rex 50% rex and 25% standard coats.

    And to complicate things further a double rex X double rex acts somewhat like a dom X dom breeding in that a double rex X double rex = 75% double rex and 25% mixture of standard coats and whats been termed a "loose rex".

    Rat genetics are just plain strange...lol

    Yes! My favorite female started out as a beautiful Tan hooded. I was actually a little bummed out she molted all her color. Now she's all Siamese.

    When I first got her. Still looking very much like a tan hooded:

    Tan starting to fade, but not noticeable yet:

    Chest and dorsal markings starting to fade:

    Her points are coming in and her hood is disappearing:

    What cuties! I can't wait to get them tomorrow and breed them into my dumbos, rexs, blues... The possibilities are endless!

    Also... Are Siamese prone to megacolon? What about the blaze Siamese you have up there, would that still be considered a high white?

    I am just wondering because I believe I had a megacolon baby and may have pinpointed the mom as odd eyed and white spot on her head.

    Siamese are not any more prone to carrying the high white gene than any other color of rat.

    Mega colon is caused by the dominate form of the high white gene, all of my rats are recessive high white so I have no issues with mega colon at all.

    Odd eyes are a result of high white, as are blazes, head spots, and any rat that has white where it's not suppose to be.
    If you got mega colon babies from an odd eye rat then you've got dominate trait high white, something that I would feed off...

    Ok so now that I have someone that understands what high white really is, I need to understand what exactly is a high white.

    It is any misplaced white marking other than an unbroken solid hooded and a self correct (higher than berkshire)? I know that there are also exceptions with this such as variegated and dalmatian.

    I guess you find out if the high white is recessive or dominant by breeding the high white to a self as the self is naturally dom?

    This is correct.

    That would be a good way.
    If your odd-eye is dominate then you'll end up with blazes right off the bat.
    If it's recessive and the self doesn't carry the recessive high white gene then you won't make any blazes or odd-eyes, just carriers.

    That's the tricky part, if the self carries the recessive high white and you make blazes right away you won't know for a fact anything without further breeding.

    Once I knew my high whites were recessive I started breeding it into everything I had, lol.

    Thank you so much Jerry. I have been doing a lot of research as to what is a high white and could never get as good of an answer (simple as it is) as you gave me.

    I am not 100% sure she is odd eyed but when I was looking at her last night, one shone ruby while the other was black. Could have been a trick of the light and worth looking into. She is also pretty old and I would like to retire her pretty soon. I have other blazes that I need to work out but I am very new into breeding still.

    Again, Thank you!
