What stage of pregnancy does the embryo split if there is twins?

In the case of non-identical twins, the two embryos are from completely different eggs and are quite independent of each other and so there is no splitting into two embryos. These are the most common type of twins.
With identical twins, it is the zygote that divides into two embryos, so you wouldn't say that the embryo divides. This usually occurs between 3-8 days after fertilization and the embryos will have one placenta and two amniotic sacs.
Sometimes it will occur before this time and each will have a placenta and a sac. Less frequently, the zygote will split up until 13 days post-conception with the embryos sharing a single sac and placenta. Complications are more likely in this case. Rarely, the split will occur after this, resulting in conjoined, or Siamese, twins.

What happens if an embryo does not completely split?
Siamese twins.
What might happen if an embryo did not completely split?
You will get conjoined twins.
Are twins just two babies or a split embryo?
no they are just purple stuff
What is having a embryo with two similar parts?
When you have an embryo with two similar parts, this means that there will be identical twins. They are formed when a single egg are split into two. Identical twins will always be the same sex.
How are animals born with two haeds?
Identical twins from the same embryo that did not split into two indeividuals completely.
What do parents do to make there twins look alike?
Identical twins are conceived by the embryo splitting into two in the early stages of pregnancy, not by anything the parents' did/do. Parents can make their kids look similar by dressing them alike.
What are twins that come from the same fertilized egg?
Unlike the single baby, this fertilized egg cell will split into two separate embryos, and grow into identical twins. This remarkable event takes place during the first week after fertilization, and can happen at several different times:At the two cell stage on days 1 to 3At the early blastocyst stage on days 4 to 6Or in the late blastocyst stage on days 7 to 9The stage at which the egg cell splits determines how the twins will implant in the uterine lining, and whether or not they share an amnion, chorion, and placenta. Basically, the earlier the splitting occurs, the more independently the twins will develop in the uterus. So, a pair of identical twins that split during the two-cell stage will each develop its own amnion, chorion, and placenta.Twins that split during the late blastocyst stage will share an amnion, chorion, and placenta.
How do babies get conjoined?
Sometimes an embryo splits after fertilization into two. This makes identical twins. When the embryo splits, but remains attached to the other, you get conjoined twins.
Is it possible to have unintentional twins after an IVF treatment?
Yes, it is. In many situations 2 embryo's will be transferred back into the mother's womb to double the chances of one or either actually hatching, though I suppose when you make that decision with your fertility specialist you will be aware of the chance both embryo's will hatch and you're willing to accept the risk (and joy!) of having twins. However even if only one embryo is transferred back, it can still split itself up resulting in identical or monozygotic twins. Rare, but possible!
What is the difference btween identical twins and fraternal twins?
Identical twins are the result of a single fertilized embryo splitting in two at an early stage and forming two viable embryos. As such, identical twins have identical DNA. Fraternal twins are the result of two distinct fertilized embryos being viable. As such, they have different DNA. They could even be different sexes.
What happens when twins are formed from one embryo?
There are smaller babies!
Why are twins formed from the same embryo?
When the embryo gets fertilized, it sometimes splits into two, making an identical twin.
