Identical twins are identical same sex babies.
Fraternal twins are babies that shared the same womb and are born within minutes and they can both be boys, or both be girls, or a girl and a boy.
Siamese twins are conjoined twins, meaning they are not separate from each other and can share hips, or legs, or arms and even hearts and other internal organs, and there was just a case recently where the baboes were attached at the tops of their heads.

Identical twins look exactly alike and have the same DNA. Fraternal twins may look similar but don't have to. Also fraternal twins could be one boy and one girl. Siamese twins are twins that come out attached to each other. I believe the egg splits into two and that is how a fraternal twin is made. Otherwise identical twins will be in the same egg.

Identical or monozygotic twins are formed from one fertilized egg (one ovum and one sperm) which splits after conception into two identical halves which develop separately. Each identical child (always the same sex) will have the same chromosones and many of the same physical attributes. Identical twins will also share the same blood type, eye and hair color.
Fraternal or dizygotic twins are formed from two fertilized eggs (two ovums and two sperms) and can result in two siblings of the same or opposite sexes. Your likelihood of having fraternal twins is dependent upon the woman carrying a fraternal twin gene and can also be affected by heredity, race, marital age and number of children previously borne. One-third of all twin births result in same sex fraternal twins and one-third are different sex fraternal twins.
Siamese or Conjoined twins are twins whose bodies are joined together at birth. This happens where the zygote of identical twins fails to completely separate.

Identical, or maternal, twins grow from a single fertilized egg that splits into two early in development. They are genetically identical.
Non-identical, or fraternal, twins grow from separately fertilized eggs at the same time. They are no more related than other non-twin siblings.
Siamese, or cojoined, twins have part of their bodies fused together and may share limbs or organs. They're called "Siamese" twins because there was a famous pair (Chan and Eng) who were from Siam.

Fraternal twins are no more closely related then other siblings. You get fraternal twins when 2 eggs are released and fertilized.
Identical twins are one egg that splits after fertilization.
Siamese twins, also called conjoined twins, are identical twins that the egg did not split completely

Fraternal twins come from two different eggs, identical twins come from the same egg, it just split in to two and Siamese twins are joined to one another.

both instruments of twins percentage a uterus--she might want to certainly experience both of you in there kicking away, so she's no longer "dumb" so some distance as that is going. There are 2 sacs--now and again same twins percentage the inner sac, yet no longer always. Fraternal twins not in any respect do. Fraternal twins are brought about by potential of two seperate fertilized eggs, while same twins are brought about by potential of a unmarried egg that splits. Boy/lady twins can't in any respect be same, yet lady/lady or boy/boy twins can nevertheless be fraternal. same sex fraternal twins can look lots alike, yet nevertheless no longer be same (Mary Kate and Ashley Olson are fraternal, even in spite of the undeniable fact that they appeared an identical even as they were youthful). the in uncomplicated words thanks to understand for particular if you're same or fraternal might want to be to get a dna try. same twins have the exact same dna even as fraternal twins have different dna (they could have dna basically as if they were siblings born years aside).

Identical are always the same sex and came from one egg and one sperm.
Fraternal can be either the same sex or different sex. They come from two eggs and two sperm that got implanted at the same time.
Siamese are identical twins that are also known as conjoined twins. They're bodies are connected.
