ABSTRACT
The microevolution of Alu element TPA-25 was tested in the experiment through the examination, observation, and analysis of population alleles distribution under the Hardy-Weinberg Theory of Genetic Equilibrium. Alu elements affect the genome by causing insertion mutations, recombination between elements, gene conversion, and alterations in gene expression. In the lab PCR was used to amplify a short piece of DNA from human genome which allowed us to look for a DNA sequence called an Alu element. Electrophoresis was used to separate DNA fragments of different sizes. The data indicated that the most individuals had the Alu element TPA-25. According to the results x2 was 1.842 because number of homozygous AA individuals without Alu insertion was 5, number of homozygous BB individuals with Alu element was 22 and heterozygous AB individuals were 13. I failed to reject my hypothesis because the p value was greater then 0.5 and less then 0.1.
