No, identical twins do, but fraternal twins come from 2 separate eggs.

Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.

Identical come from the same fertilized egg

Identical twins come from one egg and one sperm. Fraternal twins come from two eggs and two sperm.

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 are single egg twins. fraternal twins a two egg twins. fraternal

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.

identical twins, as opposed to fraternal.

They can be. While identical twins always have to be the same gender, fraternal twins usually are not. However this is not always the case. Identical twins occur because they inhabit the same egg. Fraternal twins because two eggs were fertilized at the same time. So fraternal twins could be the same gender, but usually they are of the opposite gender.

Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.

Fraternal twins come from separate eggs and are no more alike than regular siblings while identical twins come from the same egg splitting into two and have identical DNA.

Because - fraternal twins are formed from two separate eggs, which have been fertilized simultaneously. Identical twins are formed from a single egg.

They would be fraternal twins. Identical twins are created when one sperm fertilized one egg, and hat egg then splits in two. Identical twins are always the same gender, while fraternal twins can be either gender, or a mix of the two.

The genes of identical twins are identical because the twins come from one egg that has split after fertilization. Fraternal twins are not identical since they come from two eggs but have occupied the mother's womb at the same time.

Identical twins, or in-fraternal twins, are the offspring that look exactly alike and are of the same gender, sharing the same exact genetic information. In-fraternal twins occur when a fertilized ovum (egg) has divided and each went on to become an embryo containing exact same genetic information.

If two eggs are fertilsed you get fraternal twins whereas if one egg is fertilised and that develops into two individuals, you get identical twins.

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.

Fraternal twins are not identical, coming from two eggs and two sperm vs monozygotic ("identical") twins who come from one egg and one sperm that splits into two separate embryos.

Fraternal twins do not need to be separated-- Siamese or Conjoined twins do. Because fraternal twins come from two eggs, they would never have a conjoined twin condition. Conjoined twins occur when an egg divides during the early embryonic stage, but fails to divide completely, resulting in shared body parts and organs.

Twins are not necessarily identical. They can be fraternal as well. Identical twins result when one fertilized egg splits in two. Fraternal twins result from two fertilized eggs.

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.

If one egg is fertilized and as it begins to grow it divides into two separate zygotes (fetuses) then they can develop into identical twins. If two separate eggs are both fertilited at the same time they will develop into fraternal twins

identical twins came from the same fertilized egg that split while fraternal twins came from 2 different fertilized eggs.

There are two types of twins- fraternal and identical. Fraternal twins are only siblings born at the same time. Identical twins started as 1 egg that split in two after being fertilized. The DNA of identical twins is, well.... identical. At one point, they WERE the same person.

Twins will always have different personalities, no matter if they're identical or fraternal, just because everyone is different, even if you're a twin. Identical twins will look almost exactly the same, but will have slight differences (different birthmarks, etc.) because that's just how the egg grows. Fraternal twins will not look the same at all, because they come from 2 seperate eggs.
