I am dumb, I am aware. If twins have the same DNA, are they the same person from a biological standpoint?

    I’m learning so much in this thread! So even in the womb, there exists different stimuli that can affect gene expression in identical homozygous twins? What other kinds of stimuli could that consist of? I know you said difference in absorbed nutrients, but what other things can affect gene expression? Changes in pressure? like for example, could the mom sleeping on one side for a certain duration of time cause changes in blood flow to the fetuses, etc? Thanks for putting up with all my questions, haha

      It’s not very scientific of me to make these claims, I apologize. I’m not an expert in fetus development… I’m not sure these differences of stimuli matter in womb so much as to affect gene expression, but we can’t really exclude them, can we? That’s what I’m getting at. To be identical, these twins must undergo an identical development, which is impossible.
