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.

Is identical twins are more closely related than tyhe fraternal twins?
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.
Why are identical twins and fraternal twins not the exact same?
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.
Which is more common fraternal twins or identical twins?
Fraternal twins are more popular.
Why are Identical and fraternal twins similar?
They are twins!
Why are the twins identical?
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.
Why are identical twins identical and fraternal twins are not?
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.
What percentage of twins are fraternal?
There is no precise percentage of fraternal or identical twins but it is estimated that 2/3 of all twins are fraternal where as 1/3 of twins are identical.
Is identical twins are more closely related than tyhe fraternal twins?
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.

What are twins that dont look alike caled?
Fraternal. They develop from separate ova and are not genetically identical, so look different, can have different sex etc. Unlike "identical twins."
Why can fraternal twins be different genders but identical twins are are the same gender?
Identical Twins are the result of a single fertilized egg spliting in two producing two genetically identical children. Fraternal twins are the result of the mother producing two eggs each fertilized by a different sperm from the father. This can result in opposite sex twins.
Which is more common fraternal twins or identical twins?
Fraternal twins are more popular.
Are female twins that are not identical called Fraternal or Maternal?
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.
Why are Identical and fraternal twins similar?
They are twins!
What is the difference fraternal and identical twins?
Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.
How many different kid of twins are there?
There are two main types of twins: identical (monozygotic) twins, who form from a single fertilized egg that splits into two embryos, and fraternal (dizygotic) twins, who develop from two separate eggs that are fertilized by two separate sperm. There are also rarer types of twins, such as mirror-image twins and conjoined twins.
Why are the twins identical?
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.
