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.
Identical twins are called monozygotic. Fraternal twins are called dizygotic.
Fraternal twins started from two separate eggs in the mother. By comparison, identical twins started from one egg but it divided at the first stage of development into two separate zygotes (and thus two separate babies).
Female twins that are not identical are called fraternal twins. Fraternal twins occur when two separate eggs are fertilized by two separate sperm. Maternal twins refer to twins that share the same mother but can include both identical and fraternal twins.
Two separate eggs are fertilized. Dizygotic twins are the same as fraternal twins.
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.
Identical twins, due to the fact that the one fertilized egg splits, have identical DNA. Fraternal twins, since they are from separate eggs, have different DNA.
A doctor can tell you or when you give birth to them you would know. Fraternal twins is two separate eggs from the ovaries get fertilised.
If a boy and a girl are twins, they are known as fraternal twins. Fraternal twins result from the fertilization of two separate eggs by two separate sperm cells, whereas identical twins result from the fertilization of a single egg by a single sperm cell that later splits into two embryos.
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 are formed when a fertilized egg splits in two and separates, creating two embryos. Fraternal twins form when two separate eggs are fertilized.
Fraternal twins, who come from two eggs, are formed when two separate eggs are fertilized by two separate sperm. In all other aspects, their development is the same.
I am pretty sure because that is how my twins are at the moment that one placenta and two sacs mean identical twins more often than fraternal and more often identical if they are the same sex
