Did Russians (Siberiaks) absorb or displace the Native Siberians?

[Peterski]

I checked the censuses of 2010 and 2021 and in some parts of Siberia there are almost no Native Siberians left. And surely before the Russian conquest these areas were not totally devoid of people, right? So I'm wondering if some Native Siberians were assimilated by (and mixed with) the ethnic Russian settlers, or were they displaced from these areas and moved elsewhere? I'm talking about areas such as the Jewish Autonomous Oblast, Chelyabinsk Oblast, Omsk Oblast, Kurgan Oblast, Sverdlovsk Oblast, Tyumen Oblast, etc. (these areas have almost no any Native Siberians today). How much of Siberian admixture do Russians of Siberia have?

Chelyabinsk, Kurgan, Tyumen and Sverdlovsk are not Siberia anyway.

Chelyabinsk, Kurgan, Tyumen and Sverdlovsk are not Siberia anyway.

They are Siberia, they are in Asian Russia, not in European Russia.

Mixes exist, but they don't call themselves Russian.
What you're talking about is folks being absorbed into the Russian ethnos. Russian ethnos has finished forming by the 19th century. Any mixing that happened after does not contribute to the Russian ethnos, because the mestizos don't consider themselves Russian. They're aware of their status as partially-minority.
If you want to look for a region where ethnic Russians have exotic admixture, you should look in the Volga-Ural region, not Siberia.
In the volga Ural region, such groups as Mari, Moksha, Udmurt, Komi, Tatars, have contributed to the formation of the Russian populance, prior to the 19th century. There are Russians in Mari-El republic that (genetically) plot halfway between Tatars and Eastern Europeans and consider themselves fully Russian, with rodoslovnayas having not a single non-Russian name for centuries back.
Attached is my mom's illustrativeDNA 2 ways. Her roots are in Yoshkar-Ola and nearby villages. No known non-Russian admixture. You won't find a Siberian Russian with these kinds of results

Siberian Tatars are native to Tyumen, Omsk, Novosibirsk, Tomsk, and Kemerovo Oblasts.

Okay, I edited the map and added Siberian Tatars also in Tomsk.
There is not enough space to add them also in Kemerovo Oblast.
