Genome-wide investigations reveal the population structure and selection signatures of Nigerian cattle adaptation in the sub-Saharan tropics por Mauki, D.H., Tijjani, Abdulfatai, Cheng Ma, Ng'ang'a, S.I., Mark, A.I., Sanke, O.J., Abdussamad, A.M., Olaogun, S.C., Ibrahim, J., Dawuda, P.M., Mangbon, G.F., Kazwala, R.R., Gwakisa, P.S., Ting‑Ting Yin, Yan Li, Min‑Sheng Peng, Adeola, A.C., Ya‑Ping Zhang

“…In Africa, although comprehensive genomic studies have been carried out on cattle, the genetic variations in indigenous cattle from Nigeria have not been fully explored. In this study, genome-wide analysis based on genotyping-by-sequencing (GBS) of 193 Nigerian cattle was used to reveal new insights on the history of West African cattle and their adaptation to the tropical African environment, particularly in sub-Saharan region.The GBS data were evaluated against whole-genome sequencing (WGS) data and high rate of variant concordance between the two platforms was evident with high correlated genetic distance matrices genotyped by both methods suggestive of the reliability of GBS applicability in population genetics. …”
