[quote=Anonymous][quote=Anonymous]Not purely true. Division up to 3 days after fertilization means each new embryo implants separately, sharing nothing. Suggest you do some research. And, correct, identical twinning is random, matters not hereditarily.[/quote] I have done research and have actually had twins. There are 3 types and whether they are identical depends on the placenta. Identical twins always share a placenta. They are either in the same sac (mono-mono) or in different sacs (mono- di). Fraternal twins don't share a sac or a placenta (di-di). Suggest you look it up. [/quote]
