Genomic characterization of Algerian Guelmoise cattle and their genetic relationship with other North African populations inferred from SNP genotyping arrays

International audience; Understanding between and within-breeds genetic variability is essential in the choice of conservation management decisions for threatened populations. In this study we assessed the genetic diversity of the Algerian Guelmoise cattle (GUE) by analyzing data on 24 GUE individuals genotyped for the Illumina BovineSNP50 BeadChipv2. We also provided a detailed description of the population structure of GUE using comparisons with 23 worldwide cattle populations, selected as being representative of African, South European and indicine populations, in addition to four North African populations. We show that GUE is an admixed population which has strong genetic similarity to …
