Donor Proposition

Definition

A stated explanation about whose DNA contributed, distinct from how it arrived. A contributor proposition concerns whose genetic material is represented. It is distinct from identifying the body fluid or reconstructing the activity by which material arrived.

Context
DNA propositions

For example, a result may address whether a person contributed DNA without resolving whether that contribution arose through direct contact during the event.

A strong contributor-level result does not automatically provide the same evidential support for a disputed activity. Use data and propositions appropriate to the question.
