We classified the SNPs into six genomic classes, estimated and compared allele frequency distributions and heterozygosity within breed types for the different SNP classes. There was no difference between the genic and non-genic classes in their contribution to genetic variation. Among the genic regions, allele frequency distributions showed that the missense sites were subjected to selection pressure. Overall the missense sites significantly contributed less to genetic variation than the other regions. Keywords: Chicken diversity, functional annotation, SNPs
