  It also requires an egg, just with the nucleus removed

  We’ve done similar things before, these mice have 3 parents. The mitochondria come from the maternal line and have their own DNA

    It’s been a long time since I was taught this stuff, and it’s been forgotten due to disuse. Are you saying there’s still maternal DNA in the offspring, or just in the environment that nurtures them until birth?

    I did mention the eggs, BTW - I doubt that aspect can be avoided.

      Mitochondria are specialized mini-cells

      They have their own DNA like bacteria, just floating around inside their membranes. They undergo their own mitosis inside the cell, some cells can have hundreds of them

      And they always come from the egg. They’re purely maternal

      Mitochondria have DNA. Mitochondria are passed from mother to child through the egg. The egg used in the scenario would have mitochondrial DNA from the mother mouse. All of what would typically be called mouse DNA came from the two male mice. So, technically DNA from theatrical line, but only mitochondrial DNA, mouse DNA.

        Thank you for the response, but I guess this will require some research on my part to understand. Biological sciences were never my thing, I’m afraid.

    It doesn’t use the chromosome from the mother at all and still produces fertile offspring, that’s the breakthrough.

    sperms carry x chromosomes, how do you think women come to be

      “Basic Biology” MFs Try Not to Get Biology Wrong Challenge. Difficulty: IMPOSSIBLE

      The amount of men I’ve heard try to claim that it’s 100% the woman’s fault if a baby is a boy or a girl man. Fucking staggering.
