Genomic differentiation between Simmental and Holstein cattle populations from Croatia

The main goal of this study was to identify the most differentiated genome regions (SNPs), those with largest FST values, between Croatian Simmental and Holstein cattle populations. Our analyses were based on the high-throughput genomic information (Illumina BovineSNP50 BeadChip) obtained from the individuals sampled in Croatian Holstein (72) and Croation Simmental (229) populations. The most differentiated SNPs were identified on the chromosome 2 (ARS-BFGL-NGS-5831), 3 (Hapmap48051-BTA-69046, BTA-67896-no-rs), 4 (ARS-BFGL-NGS-116590, Hapmap53144-ss46525999, Hapmap51289-BTA-70566), 5 (ARS-BFGL-NGS-39379), 6 (Hapmap60182-rs29025531, Hapmap49292-BTA-75698, ARS-BFGL-NGS-109884), 7 (ARS-BFGL-NGS-11872), 10 (ARS-BFGL-BAC-12251), 11 (ARS-BFGL-NGS-83288, ARS-BFGL-NGS-100141, ARS-BFGL-NGS-89583), 16 (ARS-BFGL-NGS-101656, ARS-BFGL-NGS-106233, BTB-01570194, ARS-BFGL-NGS-22021, ARS-BFGL-NGS-30784, ARS-BFGL-NGS-18487, Hapmap60338-ss46526653, ARS-BFGL-NGS-99802), 20 (Hapmap48214-BTA-121272), 23 (Hapmap54795-rs29014478), 26 (ARS-BFGL-NGS-11271, ARS-BFGL-NGS-101647) and 29 (ARS-BFGL-NGS-115406, Hapmap58266-rs29018037, ARS-BFGL-NGS-29788). In addition, we have identified names and functions of those genes that are in the vicinity of the identified SNPs with extreme FST values. Our analysis will be extended to the population structure analyses with other worldwide Holstein and Simmental populations and the identification of genome regions that are specific for Croatian populations.
