  Identical twins, yes. You can have multiple eggs fertile at the same time. Two of my childhood friends were a boy and girl who were twins, obviously look quite different lol

    Thanks for the knowledge! I’ve been walking around knowing that Twins and Identical Twins are different; yet thinking that sex differences were developed post fertilization, like we do some in-vitro reptile shit, hahaha

    Mental apologies to my AP bio teacher, who probably taught me better! He took great pleasure in publicly slaughtering transphobic ideology, before it was cool.

  I think that’s just identical twins, but fraternal twins are two separate eggs being fertilized, which is how you can have twins of different sexes

  The concept of “twins” is far older than any knowledge of eggs (in mammals) and sperm cells. Two babies come out at the same time, language decided to call those twins.

    “Eggs (in mammals)” as opposed to what other thing in other animal groups?

      Eggs in non-mammals? Like, notably, chicken eggs?

        Ah I get what you mean now, I kept thinking which animals do not have eggs but do get twins…
