Yes, during the process, I believe the Zygote -pretty much randomly- divides into two, which leads to genetically equivalent twins (whether or not they are identical is another story).
Identical twins are genetically the same, because they come from the same fertilized egg/sperm cell zygote, which happens to split into two viable zygotes. Fraternal twins, however, come from two different egg/sperm cell zygotes, that are concurrently fertilized and remain viable.
Identical twins come from one egg and one sperm. Fraternal twins come from two eggs and two sperm.
To keep it simple and not get too technical, fraternal twins are from two eggs and two sperm that independently combine to produce a baby. Identical twins come from a single egg and sperm that divide to create two separate children. Gender is controlled by the males sperm and whether it contains the male genetic X chromosome. Since identical twins have the same sperm their genetic makeup is exactly the same (same egg and sperm used in development). Fraternal twins have two separate sperm and therefore it is possible one has the X chromosome and other does not.
Yes. Identical twins started out as one egg and one sperm cell and are genetically identical. Fraternal twins come from two eggs and two sperm cells and are no more closely related than any other sibling.
Identical twins are two children born of one egg and one sperm, that splits early on and then separates, each half then developing into a full organism. Since they came from only one egg and one sperm, their genes will be identical. Fraternal twins are two children born of two eggs and two sperms, each of them developing into a full organism. Since they did not come from only one egg and one sperm, their genes will be different. They could even be opposite sexes.
No. They have to come from the same egg and sperm to have the same DNA (and be identical). Fraternal twins are non identical twins and come from two separate eggs.

Of course; identical twins are fertilized from the same sperm and egg, whereas fraternal twins are fertilized from different sperm and egg; thus, fraternal twins would resemble each other no more than regular siblings born at different times.

Twins are identical because they come from the same egg.
There are two types of twins. Fraternal twins are produced when two eggs are released and two separate sperm fertilize them. These twins are not identical, although they may still look alike because they are siblings.Identical twins are produced when one egg is fertilized by one sperm. During the zygote stage, the egg splits into two. This creates two separate embryos and thus the children will be identical copies of each other. The same exact chromosome match.
Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.
Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.
One sperm fertilizes one egg, but before the fertilized egg can become a fetus, the egg splits and becomes two eggs made from the same egg and sperm - therefore becoming two babies.
Yes they do because they are created from the same egg when it splits so they will have the same DNA because they are identical but on the other side regular twins don't have the same DNA because they are from diffrent egg and sperm
Fraternal twins come from the fertilization of two different eggs. It can cause them to look almost the same, but they could just as easily be totally different, even different genders. Identical twins come from the splitting of only one fertilized egg, making them look exactly the same and they will always be the same gender.
