Certified Genealogical Lecturer (CGL) — Questions and Answers

Question 1: Which DNA test is most useful for finding relatives across ALL ancestral lines within approximately 5–6 generations?

mtDNA
X-DNA
Y-DNA
Autosomal DNA (atDNA) (Correct answer)

Correct answer: Autosomal DNA (atDNA)

Autosomal DNA (atDNA) tests all 22 pairs of autosomes and can detect relatives from every branch of the family tree, typically within 5–6 generations.

Question 2: What does 'endogamy' mean in the context of genetic genealogy?

A DNA mutation that skips generations
A method for phasing maternal and paternal DNA segments
The practice of marrying within a small community, causing elevated DNA sharing among members (Correct answer)
The process of comparing DNA across multiple databases

Correct answer: The practice of marrying within a small community, causing elevated DNA sharing among members

Endogamy refers to communities where people consistently marry within the same group, leading to higher-than-expected DNA sharing that can make relationship predictions less precise.

Question 3: When should documentation of a service or intervention be completed?

As soon as possible after the service is provided (Correct answer)
At the end of the week in a batch
Only when requested by a supervisor
Within 30 days of service

Question 11: What is the purpose of using visual aids in a genealogical lecture?

To replace audience interaction
To impress the audience with visuals
To clarify data and improve understanding (Correct answer)
To reduce the need for verbal explanation

Correct answer: To clarify data and improve understanding

The purpose of using visual aids in a genealogical lecture is primarily to clarify data and improve understanding. Visuals such as document images, maps, family tree charts, or research logs help illustrate complex concepts, provide concrete examples, and break down information into easily digestible formats. They enhance comprehension, reinforce verbal explanations, and keep the audience engaged.

Question 12: Which US record type is most commonly used to identify a woman's maiden name when no birth or baptismal record exists?

Marriage records, which typically name the bride's surname before marriage
All of the above are commonly used in combination (Correct answer)
Death certificates, which sometimes list the maiden name under parents
Land deeds, which may reference a married woman's former name in inheritance transfers

Correct answer: All of the above are commonly used in combination

No single record type is definitive, so genealogists typically correlate marriage records, death certificates, and land deeds to identify a maiden name.

Question 13: What unit is used to measure the length of shared DNA segments between two individuals in genetic genealogy?

Alleles
Haplogroups
Base pairs
Centimorgans (cM) (Correct answer)

Correct answer: Centimorgans (cM)

Centimorgans (cM) measure the genetic distance of shared DNA segments and are used to estimate the relationship between two individuals.

Question 14: What does the acronym 'IBD' stand for in genetic genealogy?

Identical By Descent (Correct answer)
Inferred Biological Distance
Internal Biological Data
Inherited Blood Disorder

Correct answer: Identical By Descent

IBD stands for Identical By Descent, meaning the shared DNA segment was inherited from a common ancestor rather than appearing identical by chance.

Question 15: A genealogy researcher is using a portable document scanner at a courthouse. After 50 pages, scan quality degrades noticeably with streaks appearing. What maintenance action is needed?

Restart the scanning software
Reduce the scan resolution
Clean the scanner glass and feed rollers with a lint-free cloth (Correct answer)
Replace the scanner's USB cable

Correct answer: Clean the scanner glass and feed rollers with a lint-free cloth

Dust and paper debris accumulate on the glass and rollers during heavy use, causing streak artifacts that cleaning resolves.

Reinstall the display drivers on the laptop
Replace the projector lamp
Toggle the laptop's display output using the appropriate function key combination (Correct answer)
Restart the projector

Correct answer: Toggle the laptop's display output using the appropriate function key combination

Most laptops require pressing Fn + a display key (e.g., F4 or F8) to activate external video output or duplicate the display.

Question 26: Why is root cause analysis important in quality improvement?

It replaces the need for corrective actions
It identifies the underlying cause of problems rather than just symptoms (Correct answer)
It assigns blame to specific individuals
It eliminates the need for data collection

Correct answer: It identifies the underlying cause of problems rather than just symptoms

Root cause analysis goes beyond surface-level symptoms to identify fundamental causes, enabling effective and lasting solutions.

Question 27: How long must professional records typically be maintained?

Only until the patient is discharged
For exactly one calendar year
According to state and federal regulations, often 7-10 years or longer (Correct answer)
Until the file cabinet is full

Correct answer: According to state and federal regulations, often 7-10 years or longer

Record retention is governed by state and federal laws, with most requiring 7-10 years, and longer for minors.

Question 28: What is a key component of an effective presentation style in genealogy lectures?

Avoiding visual aids to keep it simple
