Thus, Native Americans are closely related to the Ket and Selkups; the highest frequencies of Q-M242 in Eurasia being witnessed in Kets (central Siberia) at 93.8% (45/48) and in Selkups (northern Siberia) at 66.4% (87/131).<ref name="Karafet2004">T.

The Dene-Yeniseian is supported not only by shared grammatical features (both families are exclusively prefixing, head-marking, possessive shape prefixes and classifiers, and verb-heavy), but by dozens of regular correspondences between languages as well, for example:<ref>http://www.goldbeltheritage.org/wp-content/uploads/2014/02/Tlingit-Dictionary-GHF-UAS-and-Twitchell.pdf</ref><ref>https://www.unco.edu/library/pdf/Navajo_English_Dictionary.pdf</ref><ref>http://starling.rinet.ru/cgi-bin/query.cgi?root=config&morpho=0&basename=\data\yenisey\yenet</ref>
