Why do twins look different?
Fraternal twins are from different egg and sperm which cause them to be like normal siblings except for the date of birth
Identical twins come from a single fertilized ovum, and are always of the same sex. Fraternal twins come from separate ova, and may be of different sex. Its ferternal. actualy, furturnal twins are normal. identical twins are rare. identical twins are twins that look axactly alike, and furturnal twins do not look the same.
Twins will always have different personalities, no matter if they're identical or fraternal, just because everyone is different, even if you're a twin. Identical twins will look almost exactly the same, but will have slight differences (different birthmarks, etc.) because that's just how the egg grows. Fraternal twins will not look the same at all, because they come from 2 seperate eggs.
Identical twins would look the same, fraternal twins could be of different sexes. In the womb, you can easily tell the difference between fraternal and identical twins because if the twins are identical, they will share the same sac. Fraternal twins will have different sacs. You can see this in the ultrasound. After birth, it is often very difficult to tell the difference between the two types of twins because babies often look alike particularly…
Fraternal twins come from the fertilization of two different eggs. It can cause them to look almost the same, but they could just as easily be totally different, even different genders. Identical twins come from the splitting of only one fertilized egg, making them look exactly the same and they will always be the same gender.
Yes the Olsen twins sung one when they were little called "Identical Twins." Here are the lyrics: Hello! We're twins, we're twins, yes sir I am me, she is she Except when I pretend I'm her And when we switch You can't tell which is which You don't know who you're talking to 'cause we're identical, 'dentical, 'dentical, identical twins!

Many people have a difficult time telling them apart because they are focusing on the wrong things. If someone looks only at the hair, they may not see that their faces are slightly different.
Not all twins look exactly alike- Fraternal twins are brothers or sisters (or brother AND sister) that were born at the same time- but started as different eggs. Identical twins started as one egg that divided in two- they will look alike because they began as one person, and divided into two identical people. They have exactly the same genes.
Twins occur in one of two ways: 1) Identical (Maternal) Twins: These are the twins that are both of the same sex and look identical. This occurs only after the fertilized egg (an egg that has been reached and infiltrated by sperm) splits into two. This is pretty much spontaneous but some people are genetically predisposed to egg splitting. 2) Non- Identical (Paternal) Twins: These may be twins who are of different or the same…
