Native American Ancestry

Human DNA is very similar to one another, but only about 0.1% is different from the next person. That 0.1% can tell a person’s eye color, hair color, and other physical features. DNA analyst are able to take a drop of blood, the size of a dime, and duplicate the number DNA found in that drop. With the ability to duplicate DNA, analysts can have a back-up, in the event a human error were to occur. Analyst can tell you exactly where your ancestors came from and the percentage that is still inside your DNA. DNA is a very powerful tool that can identify a murder if the individual left any blood, saliva, skin tissue, hair or semen. The education needed to be able make use of the DNA consists of a great deal of science classes.

III. Today I will discuss how DNA is tested, how reliable DNA evidence is, and contamination issues that could arise in DNA evidence.

DNA testing is a critical and accurate tool in linking accused and even convicted criminals for crimes, and should be widely used to assess guilt or innocence before jail sentences are imposed. It was started up by scientists Francis C. Crick and James D, Watson in 1953 as they had described the uses, structures and purpose of the DNA “deoxyribonucleic acid” genetic fingerprint that contains organism information about an individual (testing

DNA’s certainty is dramatized in today’s society, which gives lay people the impression that DNA is infallible; however, in the case of Wayne Butler and others, the fallibility of DNA is exposed. Wayne Butler was accused of sadistically murdering Natasha Douty who was found beaten to death on Brampton Island in 1983. Wayne Butler was vacationing on Brampton Island during the timeframe of the murder; however, claimed to be jogging during this time. After submitting a blood test, Butler was eliminated as a suspect. However, Butler was arrested in 2001 for this murder because semen, which was found on the towel at the crime scene, was found to be a match. The John Tonge Centre performed a DNA test on the evidence on the towel. Butler was found innocent after it was identified that the John Tonge Centre mislabeled the test tubes containing the crime scene evidence. (“DNA Evidence”) This case proves that DNA testing may not be as reliable as we think.

Both my paternal and material families of origin are Caucasian. Ethnicity is Scotch-Irish. With reasonable accuracy I have been able to determine that my maternal great-great-grandfather (not reflected on this genogram) was living as a young man in Georgia during the Civil War period. In my maternal line I am also told that there is a Cree Indian relative in my great-grandparent line; time and place is unknown.

DNA profiling can also be used to compare the DNA of a mother, her child, and the purported father can settle a question of paternity. An example is when DNA profiling proved that Thomas Jefferson or a close relative father a child of a slave named

Perhaps the most critical improvement in criminal examination since the happening to one of a kind finger impression ID is the usage of DNA development to convict punks or get rid of persons as suspects. DNA examinations on spit, skin tissue, blood, hair, and semen can now be reliably used to association guilty parties to wrongdoings. Dynamically recognized in the midst of the past 10 years, DNA development is in the blink of an eye by and large used by police, prosecutors, shield course, and courts in the United

“These digital records and documents, combined with our proprietary online search technologies and tools, enable our subscribers to research their family history, build their family trees, upload their own records and make meaningful discoveries about the lives of their ancestors.” (Form 10-K 2016). It would appear that the purpose of the Ancestry.com service is to put the subscriber on a self-learning path to discovering more about their heritage, it wants people to be: “We are studying our mother tongues. We are dancing to folk tunes. We are climbing our family trees.” (Kabada 175). The less common but emerging method of utilizing Ancestry.com involves a subscriber receiving a DNA testing kit and sending back their data. Ancestry.com would then run the subscribers genetic information through their massive ever-growing database, and generate a report for the subscribe allowing them to trace their genetic lineage through history. “Ancestry.com sold approximately one million DNA kits for the year ended December 31, 2015, an increase of over 93% in comparison to the year ended December 31, 2014.” (Form 10-K 2016).

Native American history lacks a lot of documents so they look at other sources (oral, fossils, etc)

My lineage is complicated and blended with multiple different cultures and origins. On my maternal side, the surname from my grandfather it O’Toole which derives from Ireland and my grandmother Wells, which comes from Great Britain. Replicated on my paternal side, I have both roots from Ireland and England. Although these two countries are a powerful force in my lineage, my ancestors also have come from Pakistan, Germany, and most recently Eastern Canada. The matrilineage of my family is much easier to track and I feel as if that side of my ancestry has more history than the others may hold.

The TV show “Who Do You Think You Are” is largely accredited to boosting the popularity of Ancestry, especially with many celebrities like Lisa Kudrow participating. The show is going on 12 seasons in the UK, and thus, Ancestry has marketed very effectively to increase. Other media that has given the company lots of attention was the Momondo video. Essentially, this video started with 67 people who took a DNA test to figure out how diverse they are. Ancestry can match people across 26 ethnic regions and ethnicities to determine Many of the results shocked people, and one woman even found that she had a cousin in the room who also did the DNA test. In fact,

Another important aspect of use of the Y Chr DNA testing is in cases of missing persons ,if variety of potential reference samples are available. Since the Y Chr is passed by the father unchanged to his son except in the cases of mutations. All males of same paternal lineage will have same paternal haplotype

An individual ethnicity play a vital role in genetic testing. Racial and ethnic difference can relate to the cause, expression and prevalence of certain diseases. In some ethnic group there is an increased propensity for certain genetic disorders and knowing an individual’s ethnicity can provide additional information during genetic testing.

I do not anticipate obtaining my DNA profile. I think a genetic profile reveals a lot of interesting information such as how I am able to tolerate really spicy foods but I don't have any use for the information. Who really cares what genes I have to make me prone to like spicy foods? Once the information is out there you can't unsee it. I am concerned about the health concerns genetic profiling may reveal. I don't want to stress out about a disease I may never get. Modern day science and medicine is life-saving but sometimes I think we know too much and for me personally I feel like knowing my DNA profile is like playing God.

Genetic testing has become very popular. There have been places where you could pay to be genetically tested, such as Complete Genomics or 23andMe. The purpose of genetic testing is to look at a person’s genes, or DNA, to figure out if a person has the gene for a particular disease. DNA consists combinations
