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.
Meaning, having twins in your family will make no difference in the possibility of conceiving identical twins. Identical twins seem to occur randomly throughout the population without rhyme or reason. Fraternal twins (dizygotic) occur when two separate eggs are fertilized by two separate sperm.Two separate babies with no more in common than siblings born at different times are formed. Fraternal twins can be the same sex and/or blood type.wo separate babies with identical DNA are formed. Identical twins are always the same sex and blood type. They almost always share the same placenta but may also have two separate placentas. Depending on when the egg splits usually determines if identical twins will share the same placenta, and/or chorions and amnions.
