identical twins are formed when one sperm fertilizes a single ovum and the zygote divides into two in the initial stages of cleavage of the zygote. then, the two parts of the same zygote develop independently.
fraternal wins are formed when two sperms fertilize two different ova.

What is the different between identical twins and franternal twins?
The DNA of identical twins and of clones is, apart from random, environmentally produced mutations, 100% identical. The only difference is that clones are produced on purpose through advanced bioengineering techniques while identical twins happen as an accident of nature. Identical twins are, in a sense, natural clones.
Are identical twins developed from one egg or two?
There are at least three ways to produce twins. One is when the female produces two eggs, both of which are fertilized by the male. This is how fraternal twins are produced. Fraternal twins can be both the same sex or different sexes. Fraternal twins may only bear a slight resemblance to one another, no more than any two siblings might. (Fraternal twins can actually have different biological fathers, because the eggs may be produced a day or two apart.) Another is for the woman to produce one egg which is fertilized by the male, and then the egg divides into two. This is the traditional way that so-called identical twins are produced. Identical twins are always the same sex. (I use the term 'so-called,' because they are actually 'mirror image' twins.) A third way is for the woman to produce one egg, which then divides into two, which are both subsequently fertilized. There is a greater chance that such twins will resemble one another than fraternal twins, and they may be the same or opposite sexes.
What causes a set of twins?
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.

What is the best sexual position to get pregnant twins?
Having sex is a good way to start to conceive. However, conception of twins depends on the splitting of the egg, or upon several eggs being produced at once. Twins often run in families, leading to the strong possibility that the conception of twins is a genetic feature more than happenstance.
Which type of twins develop from two fertilized eggs?
Twins from different eggs are fraternal twins. They are siblings with the same birthdate. They are twins, but not identical, and can even be girl and boy. It is the same process taking place as a single child that a woman becomes pregnant with, but the process happens with two children at the same time. The woman releases two eggs that month instead of one, and they both are fertilized. That is how this type of twin is produced.
