Nigeria is the most populous African nation, comprising over 250 ethnic groups. The Yoruba and Fulani are the second and fourth largest ethnic groups in Nigeria, respectively. Forensic genotyping of short tandem repeats (STRs) is used in computation of Combined DNA Index System databases of individuals and ethnic groups. We examined allele diversity, haplotype frequency, haplotype diversity, and forensic genotyping data of autosomal STRs in Fulani and Yoruba residents in Ilorin, Kwara State, North Central Nigeria, in-order to further provide forensic genotyping data of these ethnic groups.

Samples of 25 Fulani males and 23 Yoruba males whose ethnicity was confirmed by three generations (paternal and maternal) were collected with informed consent using purposive sampling. All individuals in the samples were unrelated. The samples were amplified and then genotyped using the SureID® 21G PCR Amplification Kit containing Amelogenin and 20 autosomal STR loci.

Statistical analyses of forensic genotyping parameters confirmed no deviation from expectation of Hardy-Weinberg Equilibrium and no dependence of alleles between loci.

All tested loci were polymorphic. Expected Heterozygosity and gene diversity parameters showed lower genetic diversity amongst Fulanis compared to Yorubas. This is possibly due to the prevalent custom of marriage between cousins amongst Fulanis, which is forbidden in Yoruba customs.
