+_+there are two types of twins and those are:
=fraternal twins(common type) w/c means two entirely different individuals.often they are a brother and sister.they develop from separate eggs that are fertilized simultaneously by different sperm..
=the other type of twins is the identical twins,on the other hand,are nearly the same person duplicated.they started life as a single fertilized egg.but after the first division,the two cells separated and started growth all over again.sometimes this happens several times,resulting in identical triplets,quadruplets or quintuplets..
(I have a diagram here of how an identical twins and fraternal twins formed..but I can't show it here..)
