First of all, it is possible to have Altaic genes, but not show up in your Y marker. Why? Well, I think 2 reasons:
1) When the northern Han women got violated by nomads and had mixed children, they probably killed the boys and kept the daughters. That way, you have northern genes, but no Y marker.
or
2) There have been 3 instances in history where southern Chinese invaded the north:
a) The Ming restoration- they were southerners who drove out the Mongols. It
was said that Zhu Yuanzhang made northern women, Mongols and Hui
intermarry with "Chinese." Obviously, a lot of men were killed in north
during that rebellion and war. Ming Dynasty later had used a lot of soldiers
and generals from the south. Yuan Chongyuan, a famous general who
repulsed the Manchus on numerous occasions was a Cantonese.
Hakkas, Cantonese and Zhuangs.
c) KMT "Northern Expedition"- most of the troops were from Guangdong and
Guangxi.
