can identical twins have a baby together?

Identical twins are either both male or both female so cannot conceive a child together except by some dramatic genetic engineering. Even if two female identical twins had children by the same father their children would not be completely genetically identical.

Chances of Having Identical Twins While most multiple pregnancies conceived with fertility treatments are fraternal twins, the use of fertility treatment does increase your risk of having identical twins. According to one study, identical twins made up 0.95% of the pregnancies conceived with treatment.

Identical twins develop from one fertilized egg and can share the same placenta and have two separate or, rarely, one amniotic sac; fraternal twins develop from two separate eggs and grow in their own amniotic sac, according to the ACOG.

Identical twins do indeed start with identical DNA—they are the result of the same sperm from dad and the same egg from mom. The original fertilized egg divides one or more times before the resulting clump of cells splits into two. Each clump of cells goes on to become one of the identical twins.

Monozygotic or identical twins (also called "real" twins) can have individual or shared placentas, so the number of placentas can vary. Monozygotic multiples form from a single egg and sperm combination that splits after conception.

Identical (monozygotic) twins occur when a single egg is fertilized by a single sperm and divides into two embryos. This split can occur at any stage up to nine days after fertilization and its timing is critical to the way the placenta(s) and amniotic sac(s) are formed.

Yes, brother and sister can be identical twin or monozygotic twin but in very very rare case. Occasionally, in this rare case, an egg contain three sex chromosome (XXY). ... After monozygotic twins seperate in the womb, either one can have mutations and some cells can end up having slightly different DNA.

Identical twins or triplets have the same genetic identity, are always the same sex, and look almost exactly the same. Fraternal multiples develop from separate eggs that are each fertilized by a different sperm.

It is true that identical twins share their DNA code with each other. This is because identical twins were formed from the exact same sperm and egg from their father and mother. However, in the case of identical twins, early in development, this embryo divides into two. ...

Identical twins The first involves a single egg being fertilized by a single sperm. Reproduction 101, right? But then, somewhere along the way, the fertilized egg divides into two, resulting in identical twins. The chances of having identical twins is relatively rare — around 3 or 4 in every 1,000 births.

Having identical twins is not genetic. ... However, for a given pregnancy, only the mother's genetics matter. Fraternal twins happen when two eggs are simultaneously fertilized instead of just one. A father's genes can't make a woman release two eggs.

It is a basic tenet of human biology, taught in grade schools everywhere: Identical twins come from the same fertilized egg and, thus, share identical genetic profiles. But according to new research, though identical twins share very similar genes, identical they are not.

Though fraternal twins are together even in the womb, they are as genetically alike as any other normal brother and sister. That is, they don't necessarily share the exact same features as their twin, like most identical twins do.

Yes - twins can be conceived at separate times and even by separate fathers, but only within a few hours or days in-between. Fraternal twins are the result of two eggs being present and fertilized to gestate concurrently.

These single embryo transfers get high pregnancy rates, without a high chance of twins. Identical twins are slightly increased in IVF pregnancies. IUI and IVF also carry different chances of fraternal or identical twins. Fraternal twins occurs when two different eggs are fertilized by two different sperm.

The chances of having identical twins is relatively rare — around 3 or 4 in every 1,000 births. And while it may be obvious, identical twins are always the same sex, either both boys or both girls, at birth.
