Ice breakers can be used to create familiarity within the group and ease everyone into the group process. The desired end result is a more open discussion forum and pleasing environment within the group in which the group process can continue.
1 To form identical or monozygotic twins, one fertilised egg (ovum) splits and develops into two babies with exactly the same genetic information.  To form fraternal or dizygotic twins, two eggs (ova) are fertilised by two sperm and produce two genetically unique children.
There are more than just fraternal and identical twosomes; other rare twin types include âhalf identical twinsâ (when the egg splits and then each half is fertilized) and mirror image twins (identical twins who develop asymmetrically).
