Yes. In fact, twins are more likely to have twins than "non-twins" are.
Yes it is possible to have twins.
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.
Its possible. My great-uncle and great-aunt were twins. I could have been a twin, but I am not.
Yes.
it's possible but twins are rare
Of course, anything is possible. But, most usually, twins skip generations. So, a twin may be the grandparent of twins, rather than the parent.
Well im a dr so i can tell you that your son can not have any twins! its just impossible!
Twin for 1 twins for both.
No, even twins are not genetically identical.
A twin is still a single, one has twins. So, "twins' parents."
It is possible to have twins through in vitro fertilization, but "monozygotic" or identical twins are just a fortunate accident of nature which happens when a zygote splits.
Fraternal twins, or dizygotic twins, occur when two separate eggs are fertilized by two sperm cells, making them genetically similar like regular siblings. Identical twins, or monozygotic twins, result from a single fertilized egg that splits into two embryos, creating genetically identical individuals. The occurrence of fraternal twins is about two-thirds of all twin births, while identical twins account for about one-third, leading to a rough ratio of approximately 67% fraternal to 33% identical twins.
