Multiple pregnancies are a particularly interesting type of gestation, both for science and for the rest. They are especially common in Assisted Reproduction. But what is the difference between twins and twins?

 

  • Dizygotic twins or twins can come from 2 oocytes and 2 different spermatozoa, so they give rise to 2 siblings who have different chromosomes, sometimes even different sex.
  • Monozygotic twins are born in a single ovum and spermatozoon, so we will have an identical genetic load, of the same sex and physically very similar.

 

Twins

On the other hand, depending on the moment of the separation, we can have one or two placentas, one or two amniotic sacs ... the most extreme case being that of the Siamese (which is when the separation is even later).
