Genetic Genealogy and the biology behind the science.
“Inside the Genetic Genealogy being used to solve crimes.”
• Explore what technology and techniques are used by criminal justice investigators to crack cold cases with DNA technology. • Understand the strengths and limitations of the technology • Be able to think critically about the technology.
• Ancestory.com and 23andme.com are mainstream in American life and the use of technology is very important for cold cases. So, in this activity, we will learn more about the applications, strengths, and limitations of this DNA technology. • In recent years, advances in genetics and genomics have brought new dimensions to genetic testing. Genetic genealogy is the use of DNA testing in combination with traditional genealogical and historical records. Genetic genealogy involves the use of genealogical DNA testing together with documentary evidence to infer the relationship between individuals. • In a recent 60 minutes, a new story from October 21, 2018, genetic genealogy was featured as a new tool to fight crime and solve cold cases.
• View each of the two videos listed below and answer the following questions. Be sure to turn the sound on your computer on so you can hear the narration. I recommend opening each video in a separate browser tab and leaving them open so you may easily go back and forth among them throughout the assignment. You may need to watch them multiple times to answer the questions.

( 15-17 minutes into the video CeCe spells out exactly how she does itand apparently she is the best in the field of genetic genealogy)

Scientific Paper: "Inferring genetic ancestry: opportunities, challenges, and implications."
Complete this assignment by typing the answers into this document or another word document (Google docs) on your computer and printing it out to turn in before lab begins.
Write one page under 500-word reflective essay on the topic. The essay should be three paragraphs long and have proper grammar, sentence and paragraph structure. All citations should be in either APA or MLA style.
Research the topic online and use a minimum of 3 scientific outside sources.
Answer the following questions (at least 2-3 of them) in your reflective paper:
· What do we mean by ancestry?
· How exactly is ancestry measured?
· Do you think that genetic genealogy is an effective tool to help law enforcement crack cold cases?
· What are the advantages and limitations of genetic genealogy for law enforcement?
· What are the possible limitations of using genetic genealogy?
· How far back can such ancestry be defined and by which genetic tools?
