Twins form...... in one of two ways Identical twins occur when a single fertilized egg splits into two. Identical twins look almost exactly alike and share the exact same genes. Fraternal twins occur when two, separate eggs are fertilized by two separate sperm.

there are two cases
1.when two eggs are released at a time ,both of them get fused and twins are born and these twins are non identical.
possibilities are -male:female,female:female or male:male
2.in this case twins,triplets are born when the embryo divides into two or more after fusion .the embryo splits and divides into two individual and they are identical.
