Although previous studies have characterized the genetic structure of populations from Haiti and Jamaica using classical and autosomal STR polymorphisms, the patrilineal influences that are present in these countries have yet to be explored. To address this lacuna, the current study aims to investigate, for the first time, the potential impact of different ancestral sources, unique colonial histories, and distinct family structures on the paternal profile of both groups. According to previous reports examining populations from the Americas, island‐specific demographic histories can greatly impact population structure, including various patterns of sex‐biased gene flow. Also, given the contrasting autosomal profiles provided in our earlier study (Simms et al.: Am J Phys Anthropol 142 ( 2010 ) 49–66), we hypothesize that the degree and directionality of gene flow from Europeans, Africans, Amerindians, and East Asians are dissimilar in the two countries. To test this premise, 177 high‐resolution Y‐chromosome binary markers and 17 Y‐STR loci were typed in Haiti ( n = 123) and Jamaica ( n = 159) and subsequently utilized for phylogenetic comparisons to available reference collections encompassing Africa, Europe, Asia (East and South), and the New World. Our results reveal that both studied populations 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 77.2% and 66.7% of the Haitian and Jamaican paternal gene pools, respectively. Yet, European derived chromosomes (i.e., haplogroups G2a*‐P15, I‐M258, R1b1b‐M269, and T‐M184) were detected at commensurate levels in Haiti (20.3%) and Jamaica (18.9%), 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.
