                                    ALL ABOUT THE TWINS

 Twin pregnancies are special and only occur the 30% of the maximum of possibilities.

The beginning of its development begins as those of single babies, the ova and the sperm come together and form a set of two parts called zygote.That is why the twins are called monozygotic.

This zygote divides to form two separate embryos that are then identical twins.

This event occurs during the first week after fertilization and can occur in phase two cells on day 2, in the early blastocyst stage on day 4 or in the late blastocyst stage on day 6.

If the zygote has been separated more earlier more independent   are going to be.

If the twins are separated in phase two cells, they will form each their own amnion, chorion and placenta.
