Under CODIS rules, who is authorized to receive the identity of a candidate match from NDIS?
Answer: Only the laboratory that submitted the forensic profile
Only the laboratory that originally submitted the forensic profile receives the identity associated with a CODIS candidate match.
Which CODIS index stores reference DNA profiles voluntarily submitted by relatives to help identify missing persons?
Answer: Missing Person Reference Index
The Missing Person Reference Index (also called the Relatives of Missing Persons Index) stores family reference profiles for comparison against unidentified remains.
What distinguishes a partial match from a full match in CODIS?
Answer: A partial match has allele sharing consistent with a first-degree relative rather than an identical source
A partial match in CODIS indicates significant allele sharing consistent with a first-degree biological relative of the forensic contributor rather than a direct match.
Which federal standard defines the quality requirements that forensic DNA laboratories must follow to participate in CODIS?
Answer: FBI Quality Assurance Standards (QAS)
The FBI Quality Assurance Standards (QAS) specifically govern all laboratories that contribute profiles to CODIS.
What is the primary purpose of the CODIS Convicted Offender Index?
Answer: To link DNA from crime scenes to known individuals convicted of qualifying offenses
The Convicted Offender Index stores profiles of individuals convicted of qualifying crimes so they can be compared to forensic profiles from unsolved cases.
How does familial searching differ from standard CODIS database searching?
Answer: It intentionally searches for partial matches to identify potential relatives of an unknown contributor
Familial searching deliberately uses partial-match criteria to identify individuals who may be biological relatives of the forensic DNA contributor.
