South East Asia is what ethnicity?

Great answer from c_kayak (as always! Give her 'best answer').

To add an extra comment (and, because I know South East Asia quite well) ... there's no single "South East Asian" ethnicity. It's an extremely diverse area socially, culturally, linguistically, racially, historically and politicly.

In geographical terms, South East Asia is usually taken to mean the area covered by the modern countries of Indonesia, Singapore, Malaysia, Brunei, Philipines, Thailand, Burma, Vietnam, Cambodia and Laos.

It's hard to tell what that DNA report was trying to say, from your brief description. As c_kayak says, 116% doesn't make sense. Even being described as "100% Caucasian" doesn't make a lot of sense, because there's no single genetic profile which fits any definition of "Caucasian" - and there are many different defintions.

Possibly it's implying that you have some ancestry from the South East Asian region - perhaps Vietnamese or Philipino (which both have large foreign diasporas)? 16% sounds like one-sixth. Maybe one sixth of your ancestry comes from South East Asia?

In terms of "what do South East Asians look like?" - it's hard to say because it is such a diverse area. Broadly, Indonesians, Malaysians and Filipinos are of the Malay type; Thias and Vietnamese are closer in appareance to the general East Asia type, like Chinese.

Hope it helps a little bit. If you give more detail maybe we can give a more accurate answer.

You can't be 116% of anything so you must have misinterpretted the results. If you have 16% genes of South East Asian origin you could not be more than 84% other origin, whatever that would be. Also, there is no "caucasian" genetic makeup so you misunderstood that determination as well. Any legitimate genetic testing would establish the regions of origin of various mutations in your genetic material. They could tell you if you shared common genes with people from Britain or Sweden or Poland but they would not characterize you as "Caucasian" because there is no such genetic group.

16% means that at least one or more of your great grandparents had to have South East Asian genes.

mostly from vietnam,eastern india, bangladesh,burma/myanmar,camodia,laos,indonesia,possibly philipines,singapore,malaysia,nepal,bhutan,brunei, some might include southern china and east central asia,

China, Taiwan, Vietnam..Could include parts of India and Nepal..
