Thread 1/2: Every human is descended from two biological parents. And every human biologically inherits the genetic @Ancestry DNA of both of their biological parents co-equally (50% from one parent and 50% from the other) subsequent to their dad’s sperm fertilizing their mom’s egg(s). Moreover, “Genetic Ancestry DNA” is synonymous with “where someone has geographical ‘origins in’ as a matter of biological descent.” For example, some people have biological origins in any of the original peoples in the geographical area of Europe (White); some people have biological origins in any of the Black racial groups of in the geographical area of Africa (Black); some people have biological origins in any of the original peoples of the Far East, Southeast Asia, or the Indian subcontinent geographical areas (Asian); some people have biological origins in any of the original peoples of Hawaii, Guam, Samoa, or other Pacific Islands geographical areas (Native); and some people have biological origins in two or more of the above named geographical-origin groups (Multiracial, “two or more races”). Crucially, every human being shares origins/genetic ancestry DNA with both of their biological parents. As genetic ancestry DNA “refers to information about the people that an individual is biologically descended from, including their genetic relationships. Genetic information can be combined with historical information to infer where an individual's distant ancestors lived” (@genome_gov). For example, according to @NIH: “Genetic ancestry testing involves the comparison of a large number of DNA variants measured in an individual with the frequencies of these variants in reference populations sampled from across the world. The geographic region in which an individual variant has its highest frequency is assumed to be the most likely location of an ancestor who transmitted the variant to the person being tested. Ancestry testing is traditionally done for mitochondrial DNA (transmitted only by females and reflecting the origin of 1 maternal ancestor) and for Y chromosome DNA (transmitted only from father to son and reflecting the origin of 1 paternal ancestor).” Think @23andMe and Ancestry, which are DNA testing org’s. — See Biology 101 Terms Below. — See biological-geographical origin based (aka genetic ancestry DNA based) race classification categories as constructed by the the U.S. government, the Office of Management and Budget specifically, in 2/2 of thread below (the source is an official @uscensusbureau document).
