The origins of the different strains \u0000of Tswana chicken remain unknown and it is not yet clear if the different strains represent distinct breeds within the large Tswana chicken population. \u0000Genetic characterization of different strains of Tswana chickens using SNP \u0000arrays can elucidate their genetic relationships and ascertain if the strains \u0000represent distinct breeds of Tswana chicken population. The aim of this study was therefore to \u0000investigate population structure and diversity and to estimate genetic \u0000distances/identity between the naked neck, normal and dwarf strains of Tswana \u0000chickens. A total of 96 chickens (normal strain (n = 39), naked neck strain (n = 32), dwarf strain (n = 13) \u0000and commercial broiler \u0000(n = 12)) were \u0000used in the study. SNP genotyping was carried out using the Illumina chicken iSelect \u0000SNP 60 Bead chip using the Infinium assay compatible with the Illumina HiScan \u0000SQ genotyping platform. The observed heterozygosity (Ho) values were \u00000.610 ± 0.012, 0.611 ± 0.014, 0.613 ± 0.0006 for normal, naked neck and dwarf \u0000strains of Tswana chickens respectively and averaged 0.611 ± 0.016 across the \u0000three strains of Tswana chickens compared to Ho of 0.347 ± 0.023 in commercial \u0000broiler chicken.
