Genetic Ancestry Of African Americans: Article Analysis
“The Genetic Ancestry of African Americans, Latinos, and European Americans across the United States” is an article developed by the company 23andMe. The authors of this article are Katarzyna Bryc, Eric Durand, Michael Macpherson, David Reich and Joanna Mountain. 23andMe studied the genetic ancestry of 5,269 self-described African Americans, 8,663 Latinos, and 148,789 European Americans who are 23andMe customers and show that the legacy of these historical interactions is visible in the genetic ancestry of present day Americans. Although the US government has census surveys that establish fine scale self-described ethnicity at the state and county level, 23andMe look at the relationship between genetic ancestry and self-reported ancestry for each region. These studies can inform medical studies and personalized medical treatment. How …show more content…
The participants were drawn from the customer base of 23andMe and were genotyped on the illumine HumanOmniExpress platform. These participants were then asked to fill out web-based questionnaires that involved ancestry and ethnicity, state of birth and the current zip code of residence. The company than obtain ancestry estimates from genotype data using a support vector machine-based algorithm that infers population ancestry using reference panels to investigate patterns of native Americans, African and European ancestry. First, we will look into the Genetic ancestry of 5,269 African Americans across the US. The results of this study show that 1 in every 20 African Americans carry Native American ancestry, which was a higher rate than what they detected in self-reported European Americans.

    Ancestry-Biased Migration Model

    , “An estimated 82.1% of ancestors to African-Americans lived in Africa prior to the advent of transatlantic travel, 16.7% in Europe, and 1.2% in the Americas, with increased African ancestry in the southern United States compared to the North and West. Combining demographic models of ancestry and those of relatedness suggests that admixture occurred predominantly in the South prior to the Civil War and that ancestry-biased migration is responsible for regional differences in ancestry”…

    Genographic Project

    The Genographic Project initially started in 2005 headed by Dr. Spencer Wells from National Geographic and I.B.M 's biologist Dr. Ajay Royyur, set out on a mission that would change the perception of ones ancestors forever. (Geno2.0) With lead funding from the Wait Family Foundation they embarked on a long and strenuous journey to take a deeper look into; not only indigenous cultures but the general public’s ancestor. The Genographic Project embarked to do something that had never been done before collect D.N.A samples on a grand scale and keep track of similarities that they found along the way. By doing this on a large scale they would be able to have the biggest recorded data base of human D.N.A. Being able to match their findings back to ancestries that would have been thought to have been related. The project became possible with the advancements of D.N.A analysis. They obtained samples from various indigenous tribes by having them swap cells from inside of their cheeks and recording their findings. (Geno2.0) The same process was done with individuals in the general public. Dr. Spence Wells states, that in putting all this information together the general public can obtain a better idea of how we are all truly related. (IBM) Skin color or ethnic backgrounds are not truly things that make us different or similar. We are all inactuallity more alike than we could ever begin to imagine.…

    ETH 125 Historical Report On Race

    Throughout most of U.S. history, in most locations, the majority race has been White/Caucasian according to the (US Census) 72% of the population were White, the ancestry is primarily of European decent including Germany, Ireland, England, Italy, Scandinavia, and Poland, with some in the Middle East and North Africa. The highest population of the White race is in the Midwestern states. I believe that the longer your ancestors live in America the degree of mixed heritage, will become increased, because of interracial marriages, and births. Some of the larger races in US history are Native Americans, until the White settlers moved into the area in the 15th Century. Hispanic/Latino is of no particular race their ancestry is of Latin America, this race in the US was around the 15th Century, Asian and Pacific Islanders are of Far East, Southeast Asia, and Pacific Islands. Several laws were in place that specifically singled out certain Ethnic groups, some examples, (Jim Crow laws) primarily targeted Blacks. (The Civil Rights amendment) put an end to the 100-year law. (The Page Act of 1875) targeted the Asian race.…

    Of those minority groups, the Native American people had roots from Northeast Asia by most genetic accounts from a single ancestry (Smith, Jacobsson, & Crawford, Native Americans Descended From A Single Ancestral Group, DNA Study Confirms, 2009).Hispanics and Latinos were generally from North and South America, and even parts of Europe (Spain and Portugal). Blacks are generally from Africa, and the West Indies (whose people can also trace their ancestry back to Africa). Blacks had been notable minorities in this country for centuries, since the beginning of slavery. Hispanics and Latinos became a significant minority in the latter half of the 20th Century as more people immigrated from Mexico and South…

    Historical Report on African Americans in the United States

    African Americans were not always slaves and did not have citizenship. However after African Americans started to come to America, they were made into slaves, with no rights because of the color of their skin. In 1619, A Dutch ship brought the first 20 slaves to America. This was the beginning of slavery for the African Americans. Throughout history African Americans have had a hard time gaining the right to be equals and free. African American people were not to eat, use the same restroom, or even travel with a white person in the beginning. This was the way of the New World.…

    Anthropology: The Identity of a Black Puerto Rican

    For those with obvious African physical characteristics, many are often referred to as “black-” (Black-Puerto Rican, Black-Cuban, etc.) Only 5% of the population in Latin America (encompassing North/Central/South America, and the Caribbean) claim African ancestry, according to census records. With historical facts of the Middle Passage and obvious physical characteristics and cultural influences in culture, African ancestry is often the elephant in the room. My father told me of an old saying his parents taught him, “¿Y su abuela, donde es ella?” Which means “And your grandmother, where is she?” In other words, you may look Spanish, but many have a black grandmother tucked away in the house. This was a saying that was used back in the days where racial issues were dominant, especially in those with mixed…

    Multicultural Issues in the Helping Profession

    It is interesting to look at the past to see how interracial relationships have merged. John Rolfe and Pocahontas’ intermarriage in 1614 was the first to be recorded in North American history. Between 1614 and 1660, America’s first biracial children were born in colonial Jamestown, Virginia to intermarriages such as white-black, white-Indian, and black-Indian. The total number of biracial people in America by 1775 was between 60,000 and 120,000 (Cruz & Berson, 2001).…

    Over half of the population who identified as non-White are Latino/a American. Furthermore, it is noted that more than half of the population growth that occurred between 2000 and 2010 was due to an increase in the Latino/a American population. It was reported that from 2000 to 2010, the Latino/a American population increased by 43 percent thus making Latino/a Americans 16 percent of the overall U.S. population. On the other hand, a decrease in growth of the non-Hispanic White population was reported with a growth rate of less than one percent in a decade (Ennts et al.,…

    Who Constitute The Hispanics?

    The term ‘Hispanic’ recognizes people whose cultural ancestry lies first in Spain and then in the Spanish-speaking countries of Latin America which comprises of Mexico, Central America and most of South America except Brazil, and several Caribbean nations. The term gained wide spread prominence only after the 1960s. (Jorge Iber, 2005:6). Spanish and Portuguese explorers and settlers began to arrive in America in the early 1500s. With the intermingling of different communities over the years, most of the Hispanics living in the United States are of mixed heritage. In social research, the definition of any ethnic or racial group always tends to be problematic. Although they are all referred to as a whole, the Hispanics are not a homogenous ethnic or racial group as is perceived by people across the world. The term in itself could be a suitable label for people who do not comprehend the intricacies of this varied population. Despite these romanticised notions of a common identity and political cohesion, first generation immigrants never used to identify themselves as Hispanics. They have always perceived of themselves as Cubans, Mexicans,…

    African American Observation And Analysis

    To firmly grasp the underling influences that shape present-day social culture, especially in a country as diverse as America, social scientists endeavor to examine the real, un-retouched, and raw American Narrative from many different angles. What they then realize is that America is the sum of a significant amount of smaller, much more intricate, parts that can’t be easily taken apart for closer inspection without losing the elaborate levels of complexities that are tied to understanding the experiences of different ethnic groups. Thus, other methods of inspection are needed to help understand the complex political, economic, and social issues that affected the experiences of minorized groups trying to make their way into America’s history.…
