So according to my AncestryDNA test results, I am 16% "African". Out of that 16%, I supposed I would be 13% "Sub-Saharan African".

Now according to this article:

>Abstract

A line of research has revealed that a polymorphism in the promoter region of the MAOA gene is related to antisocial phenotypes. Most of these studies examine the effects of low MAOA activity alleles (2-repeat and 3-repeat alleles) against the effects of high MAOA activity alleles (3.5-repeat, 4-repeat, and sometimes 5-repeat alleles), with research indicating that the low MAOA activity alleles confer an increased risk to antisocial phenotypes. The current study examined whether the 2-repeat allele, which has been shown to be functionally different from the 3-repeat allele, was associated with a range of antisocial phenotypes in a sample of males drawn from the National Longitudinal Study of Adolescent Health. Analyses revealed that African-American males who carried the 2-repeat allele were, in comparison with other African-American male genotypes, significantly more likely to be arrested and incarcerated. Additional analyses revealed that African-American male carriers of the 2-repeat allele scored significantly higher on an antisocial phenotype index and on measures assessing involvement in violent behaviors over the life course. There was not any association between the 2-repeat allele and a continuously measured psychopathic personality traits scale. The effects of the 2-repeat allele could not be examined in Caucasian males because only 0.1% carried it.

>Highlights

>► We examine the effect of the 2R allele of MAOA on a range of antisocial outcomes. ► The 2R was related to arrest, incarceration, and lifetime antisocial behavior. ► These associations were only observable for African-American males. ► Only 0.1% of Caucasian males carried the 2-repeat allele.

I'm currently reviewing through my data.
