In presenting to obstetric nurses interested in genetics,the genetic nurse identifies the primary risk(s) associated with genetic testing as:

____________________ twins is another term for fraternal twins. These twins may be the same or different sexes and genetically are no more alike than siblings born at different times.

Many parents-to-be have questions about multiple births. Maternity nurses should be able to tell them that:

These include (choose all that apply):
