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.
3 Fraternal twins are as genetically similar as any other siblings. Just as any brothers and sisters, fraternal twins will have about half of their genetic makeup in common. They will share about 50% of their DNA, the same as any siblings. Each individual receives half of their DNA from Mom's egg and half from Dad's sperm, and so any two offspring will have some overlapping qualities.
