Race can be categorized culturally, religiously or even linguistically, but we are going to classify race by genetics. Genes can define the human population by phenotypes like skin colour or hair texture, but it can also determine the ancestry of an individual. Specifically, tiny variations, or polymorphisms in the DNA sequence occurring at different frequencies can be used to study the degree of relatedness among groups (Bamshad and Olson, 2003). These differences between groups arise from Alu transposable elements which are short pieces of DNA that have real no function in the genome, but inserting itself randomly on chromosomes. Alus are known to be useful DNA markers because not only is each insertion a unique event, but it passes from one person to another for generations. For that reason, when two people have the same Alu sequence, they should have a common ancestor. This experiment allows us to see whether race can be defined by a genetic entity, alu elements. DNA swabbed from our cheek cells are extracted, purified using Qiagen QIAmp DNA kit, amplified through PCR, dig...
