Answer

Y-DNA

Answer

Mitochondrial DNA

Answer

X-DNA

Question 2

Which term describes the process of grouping DNA matches into clusters based on shared matches to identify likely common ancestors?

Accepted Answer

Clustering

Answer

Phasing

Answer

Triangulation

Answer

Haplogroup assignment

Question 3

What is a 'false positive' in the context of genetic genealogy matches?

Accepted Answer

A DNA segment that appears shared due to population endogamy or statistical noise rather than a true genealogical relationship

Answer

A match who refuses to share their family tree

Question 4

Under BCG standards, which statement best describes how genetic genealogy evidence should be cited?

Answer

DNA test results need not be cited since they are digital

Answer

Only cite DNA when it is the sole evidence for a conclusion

Answer

Cite DNA results using the same format as census records

Question 5

What does 'phasing' accomplish in the analysis of autosomal DNA results?

Accepted Answer

It assigns DNA segments to the maternal or paternal chromosome of the tested individual

Answer

It determines the mutation rate of a DNA segment

Answer

It converts raw DNA data into a readable haplogroup

Answer

It identifies which segments are identical by descent versus identical by state

Question 6

Which BCG competency is demonstrated when a genealogist accurately interprets a DNA match's relationship range and integrates it with documentary evidence?

Accepted Answer

Evidence correlation and analysis

Answer

Client management

Answer

Archival research

Answer

Legal compliance
