The chicken divided into twelve groups four birds each according to colors and phenotype for the local and exotic chicken respectively. Blood DNA was extracted and amplified by thermocycler apparatus and the electrophoresis was done using 1.2% agarose gel for DNA bands exhibiting. The results showed high genetic similarity within the local chickens ranged between 0.78- 0.96 at an average of 0.88, while it ranged between 0.73- 0.86 at an average of 0.78 in exotic breeds. The degree of similarity between Iraqi and exotic breeds was 0.74-0.88 at average of 0.80. The calculated average of differences among each of Iraqi and exotic chickens and in between were 0.12, 0.22 and 0.20, respectively. However, the genetic distance within the local chicken, exotic breed and in between them was 0.128, 0.24 and 0.21 respectively. The study concluded that the genetic similarity was higher within local chicken groups than those of exotic breeds. %U https://www.vetmedmosul.com/article_164636_3c5ce62835132f0f6d54a22b0236981b.pdf
