yDNA haplogroups are inherited paternally.

yDNA haplogroup-N descends from haplogroup-NO [1] and is cousin to haplogroup-O. Haplogroup-N carriers originated in southern China and migrated into northern Eurasia after the last Ice Age [2][3].

High-frequency haplogroup-N carriers such as the Selkup, Nenet, and Yakut (90%) [4][5] exhibit full Chinese facial morphology [6][7][8].

Middle-frequency haplogroup-N carriers with high-frequency European mtDNA such as the Finns (60%), Latvians (40%), Lithuanians (40%), and Latvians (35%) [9] exhibit partial Chinese facial morphology [10].

Haplogroup-N carriers have elite-dominated much of Eastern Europe and Eurasia until as late as the 1800s:

Rurik (also Riurik; Old Church Slavonic Рюрикъ Rjurikŭ, from Old Norse Hrøríkʀ; c. 830 – 879), according to the 12th-century Primary Chronicle, was a Varangian chieftain of the Rus’ who in the year 862 gained control of Ladoga, built the Holmgard settlement near Novgorod, and established the Kievan Rus’. He is the founder of the Rurik Dynasty, which ruled the Kievan Rus’ and its successor states, including the Grand Duchy of Moscow and the Tsardom of Russia, until the 17th century.

Finns have the highest IQs in Europe [11]: “…if we assume a UK Greenwich meridian value of 100, this yields a Finnish national IQ of about 111, which is somewhat higher than the results of the educational achievement tests (105)…”

Finns perform better than the best of the best Europeans (urban East Germans) in educational achievement tests:

Finns and other haplogroup-N peoples are more masculine than East-Nordids (h-I) and East-Europids (h-R1a). Finns exhibit markers of comparatively higher prenatal testosterone (by proxy of postnatal measurements of (1) 2d4d ratio and (2) facial morphology) [12][13][14] that put them on par with Black Jamaicans and Zulus, and also markers of comparatively higher DHT (by proxy of (1) semen production and (2) testicle size and weight) [15]:
