Haplogroup prediction in the Ghanaian population using haplotype data of 27 Yfiler® Plus loci and TaqMan SNP genotyping

Abstract

This study describes the use of the 27 loci Yfiler® Plus kit and TaqMan™ SNP genotyping to characterise and predict the haplogroups of Y chromosomes within the four major ethnic populations of Ghana. Haplogroups were assigned using the desktop NevGen software (https://www.nevgen.org/). The E1b1a and E1b1b haplogroups are the most common in the Ghanaian population and form 95% of the dataset. The Mole-Dagomba sub-population had 4. 8% assigned to the haplogroups G, H, R1b, R2 and T. The Ewe had two samples assigned to haplogroups C and D whilst the Akan had one sample each assigned to haplogroups B, J1 and J2. The NevGen predicted haplogroups were further screened with TaqMan™ genotyping for confirmation. In conclusion, ≈ 95% of the dataset was classified as M-E1b1a using NevGen combined with TaqMan™ SNP Genotyping for confirmation. The TaqMan™ also revealed 5% as J1 and other haplogroups, using an in-house control from the J1 haplogroup.
