Just to be clear on what a Parent is: A biological parent consists of a person whose gamete resulted in a child, a male through his sperm, and a woman through her ovum. Parents are first-degree relatives and have 50% genetic overlap. A woman can also become a parent through surrogacy. However, some parents may not be biologically related to their children. An adoptive parent is one who nurtures and raises the offspring of the biological parents but is not actually biologically related to the child. Children without adoptive parents can be raised by their grandparents or other family members. <Wikipedia> Now that we are clear: The definition is provided to give you an idea of how important it is to interview your Parent(s). If you where adoptive, your Adoptive or Foster Parents may or may not be able to provide you with your genetic family's history.It only makes sense to set each of your parents up for an interview.
