Board for the Certification of Genealogists (BCG) Practice Test — Questions and Answers
Question 1: What is 'identical by descent' (IBD) versus 'identical by state' (IBS) in genetic genealogy?
- IBD refers to segments inherited from a common ancestor; IBS refers to segments that appear identical by chance or population patterns (Correct answer)
- IBD segments are always longer than IBS segments
- IBD refers to mitochondrial segments; IBS refers to Y-DNA segments
- IBD is used for autosomal DNA only; IBS applies to X-DNA only
Correct answer: IBD refers to segments inherited from a common ancestor; IBS refers to segments that appear identical by chance or population patterns
IBD segments are genuinely inherited from a shared ancestor, while IBS segments appear identical due to coincidence or shared population background rather than direct genealogical descent.
Question 2: Which of the following best describes 'negative evidence' in genealogical research?
- The absence of an expected record or entry that itself is informative (Correct answer)
- Evidence that disproves a hypothesis
- Conflicting information from two sources
- A source that contains errors
Correct answer: The absence of an expected record or entry that itself is informative
Negative evidence is the meaningful absence of an expected record — for example, the absence of a marriage record in a thoroughly searched jurisdiction can suggest the couple married elsewhere.
Question 3: What term describes the GPS element that involves examining multiple pieces of evidence together to assess their combined meaning?
- Indexing
- Triangulation
- Source evaluation
- Correlation (Correct answer)
Correct answer: Correlation
Correlation is the process of analyzing and comparing multiple pieces of evidence to understand how they relate and what they collectively indicate.
Question 4: Which U.S. repository holds the largest collection of passenger arrival records for immigrants entering through the port of New York?
- The Library of Congress
- The Ellis Island Foundation Archive
- The National Archives and Records Administration (Correct answer)
- The New York State Archives
Correct answer: The National Archives and Records Administration
NARA holds the official passenger manifests and arrival records for the Port of New York and other U.S. ports of entry as part of its federal immigration record holdings.
Question 5: Why do BCG-certified genealogists prefer to examine original documents rather than relying solely on published indexes or abstracts?
- Indexes and abstracts may contain transcription errors, omissions, or misinterpretations that could lead to false conclusions (Correct answer)
- Published abstracts are not legally admissible
- Original documents are always free to access
- Original documents are easier to cite
Correct answer: Indexes and abstracts may contain transcription errors, omissions, or misinterpretations that could lead to false conclusions
Derivative sources like indexes and abstracts introduce the risk of transcription errors or selective omission; examining the original reduces the chance of building conclusions on inaccurate data.
Question 6: What is the primary purpose of analyzing genealogical evidence?
