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.
Here are the different combinations: 1  Fraternal twins could be produced when eggs from one woman are fertilized by sperm from two different men. 2  A woman may carry twins conceived in-vitro with donor eggs, which could come from two different women. 3  Donor eggs from two different women could be fertilized by sperm from two different men. In this case, the twins may have no shared DNA unless the sperm and egg donors were related. They would be similar to step-siblings. A Word From Verywell. You are likely to have to answer the same questions about your twins repeatedly.
