Jamaican mtDNA A DNA test study submitted to BMC Medicine in 2012 states that "....despite the historical evidence that an overwhelming majority of slaves were sent from the Bight of Biafra and West-central Africa near the end of the British slave trade, the mtDNA haplogroup profile of modern Jamaicans show a greater affinity with groups found in the present-day Gold Coast region
Ghana....this is because Africans arriving from the Gold Coast may have thus found the acclimatization and acculturation process less stressful because of cultural and linguistic commonalities, leading ultimately to a greater chance of survivorship and a greater number of progeny." More detailed results stated: "Using haplogroup distributions to calculate parental population contribution, the largest admixture coefficient was associated with the
Gold Coast with most of the samples taken from the Asante-Akyem area of the
Ashanti region of Ghana(0.477 ± 0.12 or 59.7% of the Jamaican population with a 2.7 chance of Pygmy and Sahelian mixture), suggesting that the people from this region may have been consistently prolific throughout the slave era on Jamaica. Modern day Jamaicans and the
Asante people, both share the MTDNA haplogroup of L2a1. The diminutive admixture coefficients associated with the Bight of Biafra and West-central Africa (0.064 ± 0.05 and 0.089 ± 0.05, respectively) is striking considering the massive influx of individuals from these areas in the waning years of the British Slave trade. When excluding the pygmy groups, the contribution from the Bight of Biafra and West-central rise to their highest levels (0.095 ± 0.08 and 0.109 ± 0.06, respectively), though still far from a major contribution. When admixture coefficients were calculated by assessing shared haplotypes, the Gold Coast also had the largest contribution, though much less striking at 0.196, with a 95% confidence interval of 0.189 to 0.203. When haplotypes are allowed to differ by one base pair, the Jamaican matriline shows the greatest affinity with the Bight of Benin, though both Bight of Biafra and West-central Africa remain underrepresented. The results of the admixture analysis suggest the mtDNA haplogroup profile distribution of Jamaica more closely resembles that of aggregated populations from the modern-day Gold Coast region despite an increasing influx of individuals from both the Bight of Biafra and West-central Africa during the final years of trading enslaved Africans. The aforementioned results apply to subjects whom have been tested. Results also stated that black Jamaicans (that make up more than 90% of the population) on an average have 97.5% of African MtDNA and very little European or Asian ancestry could be found. Both ethnic and racial genetic results are based on a low sample of 390 Jamaican persons and limited regional representation within Jamaica.
Jamaican Y-DNA Pub Med results were also issued in the same year (2012): "Our results reveal that the studied population of Jamaica exhibit a predominantly South-Saharan paternal component, with haplogroups A1b-V152, A3-M32, B2-M182, E1a-M33, E1b1a-M2, E2b-M98, and R1b2-V88 comprising 66.7% of the Jamaican paternal gene pool. Yet, European derived chromosomes (i.e., haplogroups G2a*-P15, I-M258, R1b1b-M269, and T-M184) were detected at commensurate levels in Jamaica (19.0%), whereas Y-haplogroups indicative of Chinese [O-M175 (3.8%)] and Indian [H-M69 (0.6%) and L-M20 (0.6%)] ancestry were restricted to Jamaica.

Jamaican autosomal DNA The gene pool of Jamaica is about 80.3%
Sub-Saharan African, 10%
European, and 5.7%
East Asian; according to a 2010
