What is the differences between identical twins and fraternal twins?
Wiki User
∙ 6y ago
Identical twins arise from a single fertilized egg that for some reason split itself in two. Identical twins have exactly the same genetic make-up.
Fraternal twins arise from two separate eggs. Sometimes both of a woman's ovaries will produce an egg cell at the same time. Each of these is fertilized by a separate sperm cell (of which there are always plenty) so they have different genetic make-up. They may share the same womb and be born at the same time but are no more closely related than true brothers.

How many different kid of twins are there?
there are two types of twins-- fraternal and identical. Fraternal twins are genetically unique, and they usually have physical differences. Identical twins are identically identical, such as a clone, and have exact physcial characteristics, excluding weight and scars etc.
What is the diffence between identical twins and fraternal twins?
Identical twins come from one egg and one sperm. Fraternal twins come from two eggs and two sperm.
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.
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.
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.
What is the difference between a fraternal twins and identical twins?
If two (or more) eggs are fertilised and develop together you will get fraternal twins. Identical twins are the result of a single fertilised egg dividing into two embryos.
Differences between identical and fraternal?
identical twins are from the same egg cell that split, but ferternal twins are from 2 entirely different fertilized egg cells. Thus identical look the same and ferternal can look entirely different.
Which is more common fraternal twins or identical twins?
Fraternal twins are more popular.
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.
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.
How do you know if two twins are identical or just fraternal twins that look a lot alike?
(Person that asked the question)-Once twins are born, and old enough to determine whether they are identical or fraternal, how do you know if they are identical, or just fraternal twins that look identical? I was just curious.
