    This is seriously the most adorable cat I have ever seen!

    Just curious because I’m only half-remembering how it’s determined - Would a clone of the kitten have the same colorations?

      No. The tiny little gonads will be either gray or orange. The gonads may still be a mixture, but each individual cell will be one or the other. So the gamete produced by that cell will have the same DNA of just that cell even though the organ is a mixture.

    “It is obvious to the most simple-minded that Lokai is of an inferior breed.”

    “The obvious visual evidence, Commissioner, is that he is of the same breed as yourself.”

    “Are you blind, Commander Spock? Well, look at me! Look at me!”

    “You’re black on one side and white on the other.”

    “I am black on the right side.”

    “I fail to see the significant difference.”

    “Lokai is white on the right side. All of his people are white on the right side.”

    Beautiful cat! Thanks. Is there any particular reason to think it’s a chimera? If it’s a female, it’s more likely to be X chromosome inactivation.

      Do you get X inactivation with such clean divisions? I thought it was a stochastic process much later in development? This isn’t my area so I’m relying on something like high school biology on this one.

        I’m here for the ride, because I don’t know, either, but I feel like you are correct based on my memory from my high school biology class.

        I actually don’t know, it’s a good point. It’s definitely stochastic, but I don’t know how late in the development it happens. There are definitely cats with colours completely jumbled cats with large patches of each colour. But I just realised that colour comes from melanocytes. And melanocytes must migrate from the back, as they come from neural crest. Which strikes me as a great reason for straight division on the front (the cells coming from left and right meet there) that we see here, regardless of the origin of diversity of cell colours. So I think it shouldn’t matter, but it’s just a guess.

      I believe it’s just one cat, though if it was twins looking like that that would be extra credit fantastic.
