Paternal and maternal lineages in Cabo Verde archipelago population

Abstract

The paternal and maternal lineages of Cabo Verde archipelago were characterized using 22 Y-Single Nucleotide Polymorphisms (SN Ps) and Y-minimal haplotype (ST Rs) for paternal lineage and the two hypervariable segments (HVI and HVII) of the mtDNA control region for maternal lineage. A high variability of haplotype and haplogroup composition was found in the studied population. A total of 13 haplogroups was found with Y-SN Ps and 24 haplogroups with HVI and HVII mtDNA. Using Y-ST R minimal haplotype information, genetic distances were obtained between Cabo Verde and European/African populations. While almost all mitochondrial lineages were of sub-Saharan origin (95%), the Y-chromosome lineages reveal a high diverse composition, with more than 57% of Y lineages of European ancestry
