    Heyyy I have a correction about amber for you
    Selfs don't become silver tabbies, they have pheomelanin. It just takes longer for it to show since their body is kinda "whittling down" at the eumelanin. They're basically the same as tabby ambers, they just have extra black pigment & take longer-their stripes especially linger for extra long, but later in life they will look golden/ginger 'cept for their leathers.

    This video is what I think about when dog people make fun of cats for not having proper breeds (I don’t know why they think this)

    • @camo2156
      @camo2156 2 місяці тому +9

      its just that dog breeds are generally more distinctive than cat breeds are. mainly because dogs have been domesticated for much longer than cats have, and also because dog breeds historically have been bred for specific purposes so their behaviour and morphology are more distinct to fit those purposes. But you're right, people don't give cats enough credit for how phenotypically diverse they are!

    I’ve been wondering why my black tabby cat’s fur has warmer hues than most black tabbies I’ve seen. The theory that widebanding is a gradient trait might just be the answer I was looking for since my cat's mother was a black-golden tabby. Somehow I’ve never considered that it may be a spectrum, thank you!

  • @erro_TwT
    @erro_TwT Місяць тому +1

    isn't there the sunshine gene as well that does similar things? from what I remember, this is the definition:
    a recessive trait (appears in siberians) that's like golden but can also combine with silver/inhibitor to create something called "bimetallic." it's still being studied and is theorized to be on the extension gene.

      The inhibitor is completely dominant for the complete video. But in reality it could be incomplete with minimal difference between I/I and I/i.
      Wideband: Makes the bands on tabby's large. It doesn't affect solid color cats. Wideband is a lot like spotting. Not a lot is known of wideband, but it is not monogenetic.

    When I saw the MC1R title pop up on screen, I got really excited, because in humans, MC1R causes red hair. Specifically, there are recessive alleles on the MC1R locus that can mutate the melanocytes in such a way that they cannot produce eumelanin properly. This results in red hair, which can vary in tone depending on the parents- the dark/light of hair is one of those gradient genes, if I had to guess- but will consist only of pheomelanin.
    If you've been wondering why this excites me so much? It's because my brother and I both have red hair, and I love learning about this stuff. (Did you know that MC1R can screw with reactions to anaesthesia and pain relief medications?)

    1:58 question: why are there tabby stripes on these cats if they are solids/self cats. Are they added by the inhibitor?

    • @littlehungrywarrior
      @littlehungrywarrior  2 місяці тому +2

      It's added by inhibitor, yes :) inhibitor + solid cat = smoke, which is the ghost stripe pattern you see in the video.
      I'm not sure why! sadly the mechanics behind a lot of cat colors is understudied :(

  • @dovewing8598
    @dovewing8598 Місяць тому +1

    Question, if a ginger is always expressing the tabby gene, but doesn't have the dominant "A" agouti locus on, would that cat be able or unable to express widebanding?

    • @littlehungrywarrior
      @littlehungrywarrior  Місяць тому +1

      The cat can still express widebanding :) Google "cameo cat" or "red chinchilla," they look really cool!
      I completely understand where this question comes from. Widebanding is a "modifier" of A, so shouldn't a cat with no As not have any available to modify?
      The answer is very complicated & requires a deeper understanding of genetics, so forgive me if I have a hard time explaining.
      It's shorthand to say that Widebanding "modifies" A. In reality (though still somewhat simplified), Widebanding alleles modify what A /codes for/.
      "A" is the symbol we use to summarize & refer to the piece of DNA that codes for "make agouti banding," and "a" is the symbol we use to summarize & refer to the piece of DNA that codes for "DON'T make agouti banding."
      Ginger removes A and a from the equation entirely. It doesn't matter if a is saying not to, ginger is going to make agouti anyway.
      We say "Widebanding modifies A" bc Widebanding modifies AGOUTI, and A causes Agouti.
      Imagine your friend is a sculptor and you're a painter. Your friend makes a sculpture and leaves it on your table. You come in later and paint it. The sculpture is agouti, and you're painting widebanding onto it.
      If you come in and there's no sculpture, then you have nothing to paint (a/a on a black cat)
      One day you come in and there's a sculpture, so you paint it. You have no way of knowing your friend didn't make that sculpture - someone else did (a/a on a ginger cat).
      Of course this is all still simplified, but I think this kind of explanation will probably be more helpful to your understanding than like...a bunch of jargon about melanin-switching code lol
