In the case of identical twins, a single embryo divides into two completely separate and genetically identical embryos. Each embryo continues to grow and develop individually, but with the exact same genes as the other.
On an interesting side note: Children of identical twins are genetically as closely related to their parent's identical twin as they are to their identical twin parent. Genetically, both twins are the parent of the other's children. Also, their children are genetically half-siblings.
You have the same chance as the general population. Identical twins are a genetic accident, researchers still don't know what triggers an egg to split making two embryos from one fertilized egg.
i say that identical twins are the least rare because like me a fraternal twin i only know 1 pair of fraternal twin.
Well, as an identical twin myself, I believe there is a one out of twelve chance of having identical twins, although, I'm not 100% sure....
Women who are themselves fraternal twins have a 10% chance of producing twins, identical twin women have only a 0.6% probability of having a twin birth.
Identical twins happen by chance only; 4 per 1000 births or 0.004 probability. Fraternal twin probability is increased only if it is on the mother's side; so this does you affect your circumstance (from what you have stated). The chance of fraternal twins is 1 in 60 or 0.017. So, your probability of identical twins is 0.004 and fraternal twins is 0.017 (BTW, I have triplets).
Yes, the development of schizophrenia has a genetic component.
That would be a very unusual situation. Note that due to the normal process of genetic reshuffling that is involved in human reproduction, the children of the two couples would not be genetically identical even though their parents are.
You have the same chance as the general population. Identical twins are a genetic accident, researchers still don't know what triggers an egg to split making two embryos from one fertilized egg.
Identical twins share 100% of their genetic material, so if one twin has schizophrenia, the other twin has a high likelihood of developing it due to genetic predisposition. However, environmental factors also play a role in the development of schizophrenia, so it is not guaranteed that both twins will develop the disorder.
I don't think so, I have a fetish for diapers, but know that my parents do not, my identical twin does not and I don't believe my children do.
If there is someone who sees their identical twin they scream at each other? If there is someone who sees their identical twin they scream at each other?

Jay Mcguinnes has a twin who is not identical to him, his name is Tom and Siva Kaneswaran has an identical twin called Kumar
Yes, Bruce Boyko is Allan Boyko's identical twin brother. They share the same genetic makeup and are born from the same fertilized egg, making them twins.
There is no genetic component that results in conjoined twins. They are created by an imperfect separation of identical twin concepti.
Even though identical twins share the same genetic makeup, their fingerprints are formed by the unique interactions between genetic factors and the environment in the womb. The positioning and movement of the developing fetus within the womb can result in differences in the pressure and patterns of skin ridges, leading to distinct fingerprints for each twin.
Yes.
Siva has an identical twin brother called Kumar, and Jay has a non-identical twin brother called Tom
