Twins

A fertilized egg is a zygote. Twins can come from the same egg that splits by meosis. Identical twins come from the same egg and are the same sex, but are not clones; personality and many other things are different including mental and physical illnesses. Fraternal twins come from seperate eggs and can be different sexes.

When two twins compete, one is usually a little to a lot better than the other.
