I can confirm there was some Taino renmants in dominican dna. Only on the Mtdna though, on the female side. But it isn't too high. Although some small test have suggest mild percetages the whole country would be lower. Why, because Tainos arent the only ones with Epicathic eye fold and high cheek bones. La Republica Dominicana has a small Taino Component mixed with a large african one and an european one thats near the same % as the african, abit less. From highest to lowest i'd say the whole of d.r is African, European(Iberian), Taino. The african is obviously the highest component. If d.r had higher European and Taino components it would look more like the whole of puerto rico.
One thing not mentioned is that alot of the african brought to the dominican republic came from areas were they posses similar features to Tainos, as far as the eyes and cheekbones. D.R had a huge importation of Congo/Angolan/Zaire, this reflects in our language, we have plenty of kongo words, Mofongo, Mondongo, Kamumbo, Kimbamba, Bembe, Toto. We also have some Nigerian blood as well, if u look up pictures of angolans and congolese u will see alot with high cheekbones and almod or slanted eyes. Which they got from some of their ancestors called the Kohisan people of South Africa.
So a combination of a good amount of africans with high cheekbones and slanted eyes, (not as much as tainos but close) with a small taino percentage can make a person look more taino then he is genetically. So observation is not good enough in d.r to asses the Taino component.
Look at this guy, he's Angolan.

So as you can see they have eyes very close to Tainos, if anythign Kohisan have even more slanted eyes then Tainos. Of course i'm not denying the Taino precense in d.r, but alot of people on this thread are exagerating it. And that comment about few africans brought to d.r, thats obviously not true. You can't rely on statistics because a very large amount of africans brought to d.r during slavery came illegaly! they werent recorded in the Statistic books, alot of them were smuggled in from Curacao (The Dutch).
A great example of an African and a white mixture that looks like it has taino or native american is Barrack Obama. LOL.

He looks like alot of dominicans, hell he looks like my grandfather.
Yet his mother is a full blooded white american woman, and his father is a full blooded kenyan man.
