Examples of indigenous Amerindian mtDNA haplogroups (inherited in the maternal line) include A2, A2d, A2f1a, A2w1, A4, B2, B2a5, C1b6, C1b14, C1c, D2a, D4h3a, X2a1b, X2g, and many others. For example, A2 is common in Mexico, C1b2 and C1b4 are found in Puerto Rico, C4c1a is found among the Cherokee, and X2a1 and X2g are found among the Ojibwe.
Indigenous Amerindian Y-DNA haplogroups (inherited in the paternal line) are within branches of Q, R1, and C. They include Q-M3, Q-M19, Q-L54, Q-Z780, Q-MEH2, Q-SA01, Q-M346, Q-P89.1, Q-NWT01, R1-M173, and C-P39. 83 percent of indigenous South American males belong to Q-M3. Q-M19 is especially common among the Ticunas of the Amazon. C-P39's prevalence peaks among the Athabaskans. Note that R1 is the genetic ancestor of R1a and R1b, but those two branches aren't native to Amerindians.
Much of the Amerindians' genetic diversity was lost due to a massive decrease in the Amerindian population during the early colonialist era. The causes included Europeans diseases for which the natives had no immunity (including smallpox and measles) and, in some cases, wars. As a result, some mtDNA haplogroups that used to exist up to the 1500s have become extinct. Many branches of A2, B2, C1, and D1 were lost, and there once were Amerindians bearing branches of M.
Family Tree DNA, based in Houston, Texas, U.S.A., is a direct-to-consumer company that performs testing of mtDNA and Y-DNA lines. This can verify your Amerindian ancestry in a particular uniparental lineage. If you belong to a bonafide Amerindian lineage, you can apply to join such projects hosted by the company as "American Indian Proj", "Q1a3a1-AmerIndian", "Worldwide Mitochondrial Haplogroup B Project", and/or "A2 mtDNA Haplogroup Project".

Autosomal DNA represents the vast majority of your DNA and is comprised of sections of DNA you inherited from all of your great-great-grandparents and many of their ancestors.
Amerindian ancestry represents a blend between ancient East Asian ancestry (their majority element, approximately 70 percent) and ancient North Asian ancestry that is also related to West Eurasians.
Among the major direct-to-consumer autosomal DNA testing companies, AncestryDNA is currently the best at detecting and reporting accurate quantities of Amerindian ancestry. This is due in part to the reference samples they compare their customers to. However, as good as it can be, AncestryDNA occasionally somewhat overestimates the amount of Amerindian ancestry for some of its testers, and occasionally they assign some "Amerindian" ancestry to some peoples of northern Eurasia including some Russians and Mongolians.
MyOrigins version 2.0, introduced on April 4, 2017 as part of Family Tree DNA's Family Finder autosomal DNA test, divides Amerindian DNA into two categories: "North and Central America" and "South America". Some people occasionally get false trace readings of less than 2% of one of these elements, but if you score more than a trace it usually represents real Amerindian ancestry from the Americas as opposed to shared ancient origins in Siberia.
Out of the free ethnicity estimation calculators at GEDmatch, Eurogenes K36 is among the best at minimizing noise or false readings of Amerindian ancestry, although it doesn't always do a perfect job. Eurogenes K36's reference population consists of 4 Colombians, 6 Karitiana, 4 Mayans, 5 Peruvians, 7 Pima, and 3 Surui.
Indigenous reference populations that had been used by GEDmatch's free MDLP K13 Ultimate calculator included Miwok, Tsimsian, Athabaskan, Haida, Quechua, Chachi, Chilote, Totonac, Zapotec, Pima, Mixtec, and Wayuu, among others. However, this now-defunct calculator gave noise readings for Amerindian affinity to some people who don't really have any Amerindian ancestry. Its replacement, MDLP K16 Modern, is somewhat better in this regard but still a little noisy. K16 apparently uses some or all of the following populations — Karitiana, Surui, Piapoco, Pima, Mixe, Mixtec, Athabaskan, Cachi, Tlingit, Wichi, Colla, and/or Quechua.
GEDmatch's free MDLP K23b calculator's Amerindian estimates are based on 100 Ticuna samples, while its Arctic element is based on 94 Eskimo samples. This calculator also gives out noise readings.
Individual members of the Navajo and Yaqui tribes from the United States, the Nahua tribe from Mexico, and Mayan peoples from Guatemala are among those who have submitted their DNA to 23andMe for autosomal testing.
The ALlele FREquency Database compiled by Kenneth K. Kidd of Yale University includes data on particular autosomal alleles found in the Cheyenne, Muscogee (Creek), Pima, Maya peoples of North America and the Guihiba, Karitiana, Quechua, Surui, and Ticuna peoples of South America. For instance, the 1540C allele (of East Asian origin) in the EDAR gene is reported by the database to be found among 95.5% of Cheyenne, 59% of Muscogee, 99% of Pima from Arizona, 97.7% of Pima from Mexico (129 out of 132 individuals in two studies), 86.6% of Maya people from Mexico's Yucatán Peninsula (123 out of 142 individuals in two studies), 77.3% of Guihiba from Colombia, 90.5% of Quechua, 94.5% of Ticuna, 77.5% of Surui (79 out of 102 individuals in two studies), and 99.3% of Karitiana (137 out of 138 individuals in two studies).
"Genomic evidence for the Pleistocene and recent population history of Native Americans" by Maanasa Raghavan, Matthias Steinrücken, et al. in Science (July 21, 2015). ("Using ancient and modern genome-wide data, we find that the ancestors of all present-day Native Americans, including Athabascans and Amerindians, entered the Americas as a single migration wave from Siberia no earlier than 23 thousand years ago (KYA), and after no more than 8,000-year isolation period in Beringia. Following their arrival to the Americas, ancestral Native Americans diversified into two basal genetic branches around 13 KYA, one that is now dispersed across North and South America and the other is restricted to North America. Subsequent gene flow resulted in some Native Americans sharing ancestry with present-day East Asians (including Siberians) and, more distantly, Australo-Melanesians.")
"Reconstructing Native American Population History" by David Reich, Nick Patterson, et al. in Nature 488:7411 (August 16, 2012): pages 370-374. ("We show that Native Americans descend from at least three streams of Asian gene flow. Most descend entirely from a single ancestral population that we call 'First American'. However, speakers of Eskimo-Aleut languages from the Arctic inherit almost half their ancestry from a second stream of Asian gene flow, and the Na-Dene-speaking Chipewyan from Canada inherit roughly one-tenth of their ancestry from a third stream.")
"A Reassessment of the Impact of European Contact on the Structure of Native American Genetic Diversity" by Keith Hunley, Kiela Gwin, et al. in PLoS ONE 11:8 (August 31, 2016): e0161018. Includes autosomal DNA data from such tribes as Ojibwa and Cree in Canada, and in Latin America the following: Pima, Maya, Zapotec, Mixtec, Guaymi, Cabecar, Quechua, Inga, Wayuu, Piapoco, Guarani, Karitiana, Ache, and more tribes. Examines their degrees of Amerindian DNA versus foreign admixture, and differences in regional clusters of Amerindian DNA within the Americas. ("We found that 1) European and East Asian ancestry estimates decline as K [number of ancestral clusters] increases, especially in Native Canadian populations, 2) a north-south decline in gene diversity is driven by low diversity in Amazonian and Paraguayan populations, not serial founder effects from Beringia, 3) controlling for non-Native American ancestry, populations in the Andes and Mesoamerica have higher gene diversity than populations in other regions, and 4) patterns of genetic and linguistic diversity are poorly correlated.")

("All methods detected Central and West Siberian ancestry exclusively in a fraction of Na-Dene individuals, but not in other Native Americans. [...] we have modelled a gene flow from a Siberian population that split 6,500-7,000 years ago into the ancestors of Na-Dene. Our results are consistent with a Paleo-Eskimo admixture into the First American ancestors of Na-Dene, and a much later and less extensive bidirectional admixture was detected between Na-Dene and Neo-Eskimos.")
The HLA is located on chromosome 6 and regulates a person's immune system. Many different HLA types exist in world populations and some are more frequent in particular continents and regions.
"A time transect of exomes from a Native American population before and after European contact" by John Lindo, Emilia Huerta-Sánchez, et al. in Nature Communications 7 (November 15, 2016): article number 13175. A discussion focusing on HLA types among pre-modern and modern First Nations peoples of British Columbia including Tsimshian people, who have become admixed with Europeans ("we analyse 50 exomes of a continuous population from the Northwest Coast of North America, dating from before and after European contact. We model the population collapse after European contact, inferring a 57% reduction in effective population size. [...] The important immune function of HLA-DQA1 supports an ancient adaptation to the environments of the Americas. The modern individuals show a marked decrease in the frequency of the associated alleles [...] This decrease is likely due to the environmental change associated with European colonization [...] the selection pressure shift could correlate to the European-borne epidemics of the 1800s")

Many speakers of the Spanish, Portuguese, French, and English languages in the Americas descend in part from Amerindians. These include the peoples of Acadia in northeastern Canada, of Mexico, of Puerto Rico, of Brazil, and many other places. In Virginia, Pocahontas of the Powhatan tribe married an Englishman and they have thousands of descendants alive today in the United States.
A small proportion of Amerindian ancestry is also found among Spaniards living in Spain. Some of them descend from the Aztec Empire ruler Moctezuma II.
Small percentages of Amerindian ancestry are found among some Filipinos of the Philippines and Chamorros of Guam due to immigration of part-Amerindian Mexicans centuries ago.
"The Genetic Ancestry of African Americans, Latinos, and European Americans across the United States" by Katarzyna Bryc, Eric Y. Durand, et al. in American Journal of Human Genetics 96:1 (January 8, 2015): pages 37-53. Table 1 shows that African-Americans on average have 0.8% genome-wide Native American ancestry. The authors estimate that "about 22% of African Americans carry some Native American ancestry". European-Americans on average have 0.18% genome-wide Native American ancestry. Only a small percentage of European-Americans have any at all, and the authors estimate that Native American admixture is most common among European-Americans who live in Louisiana, North Dakota, and various other southwestern and western U.S. states. It's no surprise that Latinos in the U.S. have far higher proportions of Native American ancestry.

DNA.LAND, a non-profit research project by the New York Genome Center, accepts uploads of data from customers of AncestryDNA, Family Tree DNA, and 23andMe. DNA.LAND attempts to separate non-specific "Native American" from "Amazonian" beginning on April 8, 2016.
The reference samples for their "Native American" category are: Bolivians in Bolivia, Piapoco in Colombia, Mayans in Mexico, Mixe in Mexico, Mixtec in Mexico, Pima in Mexico, and Zapotec in Mexico.
The reference samples for their "Amazonian" category are: Karitiana in Brazil and Surui in Brazil.

Carlos D. Bustamante, a professor of genetics at Stanford University in Stanford, California, U.S.A., has gathered additional Amerindian samples to try to find out which specific tribes contributed to a person's autosomal DNA.
His test isn't yet available at any direct-to-consumer lab. Bustamante's lab says samples will be collected later from the public – but not yet – but if you contact them using the web survey on their website they will get back to you later. I believe you should only contact them if you have a high amount of Amerindian ancestry.
Below are autosomal admixture results for celebrities who have had their autosomal DNA analyzed by Bustamante's lab on PBS's Finding Your Roots television show:
