The majority of the people in the world have the Rh+ blood type. However, it is more common in some regions. Native Americans and Australian Aborigines were very likely 99-100% Rh+ before they began interbreeding with people from other parts of the world.
In Aboriginal individuals we found that group O was more common than A in the 'Northern' NT, whereas there was similar distribution of the groups in 'Central Australia'. Conclusions: We found a significant difference in ABO and RhD blood groups between Aboriginal and non-Aboriginal individuals in the NT (P < 0.001).
Most common blood type by ethnicity
African American: 47% O-positive, 24% A-positive, and 18% B-positive. Latin American: 53% O-positive, 29% A-positive, and 9% B-positive. Asian: 39% O-positive, 27% A-positive, and 25% B-positive. Caucasian: 37% O-positive, 33% A-positive, and 9% B-positive.
They defined. a 'full-blood' as a person who had no white blood, a 'half-caste' as someone with one white parent, a 'quadroon' or 'quarter-caste' as someone with an Aboriginal grandfather or grandmother, a 'octoroon' as someone whose great-grandfather or great-grandmother was Aboriginal.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
The blood type of B negative is also uncommon, occurring in "2% of Caucasian, 1% of African American, 0.4% of Asian and 1% of Latino American" populations, says the Red Cross.
Doing your family history may help you obtain proof of your heritage. You might find a birth, death or marriage record that traces your family to a particular Aboriginal station or reserve. Or you might have oral history stories that can connect you to a particular area or person or photograph.
It's possible, depending on how distant the Indigenous Australian ancestor is, that you share too little DNA with them for our DNA test to detect it. A DNA test is not any kind of prescription of identity; rather, a person's genetic makeup is only one part of their story.
Today, Aboriginal and Torres Strait Islanders make up approximately 3.3 percent of the total Australian population, or around 800,000 of 25 million people. First Nations people continue to have a much younger age profile than the non-First Nations population.
Based on the primary races hypothesis, it was thought that in the three major races of man, blood groups A in Europe, B in Asian, and finally O in South America have been emerged and gradually due to the migration and mixing of the races, became the present situation.
Type O is particularly high in frequency among the indigenous populations of Central and South America, where it approaches 100%. It also is relatively high among Australian Aborigines and in Western Europe (especially in populations with Celtic ancestors).
Recent work has demonstrated an association between ABO blood types and COVID-19 risk. Using data from Wuhan and Shenzhen, Zhao et al. found a greater proportion of A and a lower proportion of O blood types among COVID-19 patients, relative to the general populations of Wuhan and Shenzhen [4].
A is the most ancient - so-called wild type. That's what we call genes, the way they start before they begin to mutate and turn into things that exhibit selective survival advantages. So about five million years ago, this mutation pops up called group O. And around that time, and subsequently, group B developed.
Based on the Australian Bureau of Statistics (ABS) projections, the number of Indigenous Australians in 2021 was estimated to be 881,600.
Genetic studies have revealed that Aboriginal Australians largely descended from an Eastern Eurasian population wave, and are most closely related to other Oceanians, such as Melanesians.
Aboriginal people can be dark-skinned and broad-nosed, or blonde-haired and blue-eyed. Let's get rid of some myths!
The findings have been published in the Journal of Human Genetics. Dr John Mitchell from La Trobe's Department of Biochemistry and Genetics, who led the study, said the research revealed there was a high level of genetic diversity among Aboriginal Australians.
However, Dr Misty Jenkins, who leads the Division of Immunology lab at the Walter and Eliza Hall Institute of Medical Research in Melbourne, said the ability to test DNA for Aboriginal genealogy does not exist.
The islands were settled by different seafaring Melanesian cultures such as the Torres Strait Islanders over 2500 years ago, and cultural interactions continued via this route with the Aboriginal people of northeast Australia.

We prefer a letter from an Indigenous organisation to confirm your heritage. However, we will also accept a letter from a Community Elder. Use the Confirmation of Aboriginal and Torres Strait Islander descent letter to confirm your heritage.
Each person has two Rh factors in their genetics, one from each parent. The only way for someone to have a negative blood type is for both parents to have at least one negative factor. For example, if someone's Rh factors are both positive, it is not possible for his or her child to have a negative blood type.
The gene for blood group B first appeared in significant numbers somewhere around 10 to 15,000 B.C., the tail end of the Neolithic period, in the area of the Himalayan highlands now part of present day Pakistan and India.
