Oh my god! 😂 There's no crime gene, but there is a "propensity to shoot and stab someone gene". It's the 2-repeat allele of the MAOA gene. African-Americans are 50 times more likely to carry this gene. Ahahahaaaaaaaaaahaha "Analyses revealed that African-American males who carry the 2-repeat allele are significantly more likely than all other genotypes to engage in shooting and stabbing behaviors and to report having multiple shooting and stabbing victims."
