All Tunisian data were also analysed against 40 worldwide populations.
The researchers analyzed 4666 male skulls from 105 worldwide populations.
The actual incidence differs based on worldwide populations, geography, and income.
First, at most genetic loci, apportionments of human genetic diversity find that worldwide populations are genetically similar.
Recent studies have highlighted their utility in forensic HID and several panels based on biallelic markers have been described for worldwide populations.
As shown in Table 1, African populations display the highest heterozygosity compared to all other worldwide populations.
DXS225 is a unique event polymorphism characterized by a variable Alu insertion that can be seen in all worldwide populations, except in Amerindians [5].
Although a considerable number of worldwide populations have been screened for these variants, results from Sub-Saharan populations are very scarce in the literature.
Furthermore, an in-depth study using the Illumina HumanHap550 BeadChip surveyed copy number variation on individuals from 29 different human worldwide populations [29].
When all 115 worldwide populations were considered, a weak but significant (at level 5%) correlation was found between genetic and geographic distances (r = 0.05, p = 0.04, Table 1).
We decided not to screen for mutations in the genes PINK1, DJ-1 and ATXN2 given the low frequency of mutations in these genes in worldwide populations.
