N2  - Random Amplified polymorphic DNA (RAPD) markers was used to analyze the genetic Structure of five indigenous Egyptian's chicken populations including Fayoumi. Dokki-4. Golden Montazah, Silver Montazah. and El-Salam based on the taxa generated by the analysis of ten RAPD markers. The population genetic distances were estimated by using two cluster algorithms (UPGMA & NJ neighbor-joining) accompanied with ten, similarity coefficients, comprising Jaccard. Sorensen-Diee. Russel & Rao, Rogers & Tanimoto. Simple Matching. Pearson Phi. lance& Williams, Mountford. Michael and Kulchenzky-I. the results demonstrated that for almost all methodologies. The Jaccard and Sorensen-Dice followed by Simple Matching coefficients. Revealed extremely close results because bath of them exclude negative co-occurrences. Due to the fact that there is no guarantee that the DNA regions with negative co-occurrences between two strains are indeed identical, the use of coefficients such as Jaccard and Sorensen-Dice that do not include negative co-occurrences was imperative for closely related organisms along with the NJ neighbor-joining cluster algorithm
