Genotyping Chips: A Case Study Essay

it is impossible to tell what her paternal haplogroup is without knowing what her father’s paternal haplogroups are, while men have a Y chromosome which makes it possible for their paternal haplogroup to be found. Everyone has Mitochondrial DNA so both men and women can find their maternal haplogroup, however, you will need to conduct a test to find out. To conduct a test, you may need a subscription to Ancestry.com, or pay for 23andMe. When you receive your DNA kit, you will have to provide a sample of your DNA, which likely will be saliva. Once it is contained it should be sent back to a CLIA (certified) lab for processing. There, along with hundreds of other organized samples, it is inspected to ensure that there is enough saliva to be used. Only 0.5% of saliva is made of cells so there needs to be enough. If there is enough it is entered into the lab inventory system where machinery is used to extract DNA from cells. After that, it is amplified (copied) so that there is enough to analyze. Genotyping chips capture key features about your health and ancestry. Your DNA is placed on the chip and attached through a hybridization process. Any last analyses are made on computers by reading the chip’s data. This process often takes about 3-4 weeks, but once it is finished, your DNA may reveal something …show more content…
Two people of entirely different ethnic backgrounds can be more genetically similar than two people of the same ethnicity. Genetics show much more than where people come from. DNA shows haplogroups from thousands of years ago and can even show if somebody has a neanderthal ancestor. These insights are provided to help you better understand what your DNA contains and how it can affect your life. Conclusively, it is important to understand what ancestral DNA can be used for and learning about what it means to you. That being said, it’s time to welcome you to
