Introduction: Hardy Weinberg theory was an effective tool for recognizing the different genotypes from one generation to the next and each allele frequency. This theory notifies us by how Mendelian inheritance was the lead for all genetic variation and it can be used to follow Mendelian’s rules of segregation and the combination of alleles. Polymerase chain reaction was one of the essentials that is used in the Hardy Weinberg theory of genetic equilibrium which was used in determining the presence of ALU element using TBA 25. The importance of using PCR is to make more copies of small pieces of DNA from human genome to look for the presence of ALU element. Every human genome contains approximately 5% of Alu element. In order for Hardy- Weinberg theory of equilibrium to work, certain conditions have to be taken place such as mating cannot be random, no mutation in alleles, has to be big population, populations have to be separated from each other, and no natural selection. For us to be able to determine if Hardy Weinberg experiment has taken place, we used a type of statistical test to determine the difference between what we expected in terms of what alleles and their genotypes and what we observed in the gel which is known as Chi-square test. This test helped us by using the table to know if our hypothesis should be rejected or not depending on what our P-value which is the probability between what we expected and what we observed is due to random chance. In Hardy Weinberg,…
