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 making up 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 (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. African paternal DNA 66.7%, European paternal DNA 18.9%, Chinese paternal DNA 3.8%, Indian paternal DNA 1.2% In Jamaica, Guyana, Suriname and Trinidad, a percentage of the population of people are of Indian descent (from paternal Grandfather), some of whom have contributed to Afro-Asian-Caribbean children. Guyana Between 1853 and 1879, roughly 14,000 Chinese indentured workers arrived in British Guiana on five-year indenture contracts to work on the colony's sugar plantations. They soon integrated into the local culture, converting to Christianity and learning English. The majority of workers were unmarried men, and intermarried with local Indo-Guyanese and Afro-Guyanese women. Trinidad and Tobago The country is known for having a large Indian population stemming from the 18th and 19th-century colonial plantation economy and people of Indian descent now make up a narrow plurality. In Trinidad and Tobago, persons of African-Indian mixed descent are called "douglas". One of the country's most notable Afro-Asians is its former President George Maxwell Richards and singer Nicki Minaj. United States In 1882, the Chinese Exclusion Act was passed and Chinese workers who chose to stay in the U.S. could no longer be with their wives who stayed behind in China. Because White Americans looked at Chinese labor workers as stealing employment, they were harassed and discriminated against. Many Chinese men settled in black communities in states such as Mississippi and, in turn, married black women. In the mid-19th to 20th centuries, hundreds of thousands of Chinese men in the U.S., mostly of Cantonese origin from Taishan, migrated to the United States. Anti-miscegenation laws in many states prohibited Chinese men from marrying white women. After the Emancipation Proclamation, many intermarriages in some states were not recorded and historically, Chinese-American men married African-American women in high proportions to their total marriage numbers due to few Chinese-American women being in the United States. After the Emancipation Proclamation, many Chinese-Americans immigrated to the Southern states, particularly Arkansas, to work on plantations. For example, in 1880, the tenth
