Abstract :

To research effects of the artificial selection of G. gallus on G. domesticusâ�� nucleotide diversity of immune genes, sequence polymorphisms of G. domesticus (23 genes), G. gallus (23 genes), Gallus lafayetti (17 genes), and G. sonneratii (17 genes) were obtained from GenBank. The data set included 819 polymorphisms. Immune gene polymorphism and selection efficiency in the data from those four species of Gallus were calculated. By calculating the �¸w (Watterson's estimator) of each site, an average �¸w for each species, and the minimum number of re-combinations in each species and estimating the selection efficiency for G. domestics and G. gallus, no significant nucleotide diversity nor genetic diversity �¸w difference was found between G. domesticus and G. gallus. The results indicated that the patterns of genetic diversity in G. domesticus were strongly influenced by recombination and because Tajima's D has a negative value, recombination was the main mechanism responsible for the immune gene evolution of G. gallus.
