No. They have to come from the same egg and sperm to have the same DNA (and be identical).
Fraternal twins are non identical twins and come from two separate eggs.

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.
If twins aren't identical what are they called?
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.
How are twins born non-identical?
Non identical twins are formed when the mother releases two eggs and both those eggs are fertilised. hope this helps :)
Why there is a fraternal and the identical twins?
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.
What might happen if 2 eggs were released from the ovaries during 1 menstrual cycle?
If both are fertilised they become fraternal twins (non-identical).
Why are some twins identical and some not?
The reason why some twins are identical and some are not starts in utero. Identical twins occur when one egg is fertilized and it splits to create two embryos. Nonidentical twins come from different fertilized eggs.
How two baby's are born from one mother at a time?
They are known as 'twins'. Identical twins are when 1 fertilised egg divides and each half develops separately in the womb, sharing the same genes. Non-identical twins are when two eggs are fertilised by two separate sperms.
What are nonidentical twins?
Non-identical twins occur when the mother ovulates and two separate eggs are released and fertilised. This is different to identical twins, they occur when one original egg splits n two and develops in tandem. then yo have sex
How do twins form?
Identical twins form when an egg is released from the ovary and is fertilised by a sperm and then splits into two. They then form naturally. Non-identical twins form when two eggs are released from the ovary and then fertilised by a sperm. They also form naturally. Identical twins have to be of the same sex (two boys or two girls) because they have come from the same egg which contains the same DNA. Non-identical twins can be either boy and girl or of the same sex (two boys or two girls) because they came from two different eggs and so have two different sets of DNA.
How do you get identical and non identical twins?
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
How are unidentical twins formed?
Two eggs are released and both get fertilised.
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.
