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 are a single fertilized egg that divided itself into 2 embryos.
fraternal twins are 2 separately fertilized eggs.
Any set of twins that are not identical (whether it's boys or girls or a combination of the two) are fraternal twins.
Yes they are identical twins
Twins who are of the opposite sex or do not look alike are fraternal twins ~ not identical. This means that at the time of their conception ~ two eggs were fertilised. In the case od identical twins, one egg is fertilised and split in half.
if they share 1 heart then yes they do. but if they have different hearts then they do not
Twins can only be identical if they are the same sex. If they are boy and girl, they 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.
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 are more popular.
They are twins!
Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.
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.
(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.
Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.
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.
identical
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.
