Breadtube if it didn't suck.
Post videos you genuinely enjoy and want to share, duh. Celebrate the diversity of interests shared by chapochatters by posting a deep dive into Venetian kelp farming, I dunno. Also media criticism, bite-sized versions of left-wing theory, all the stuff you expected. But I am curious about that kelp farming thing now that you mentioned it.
Low effort / spam videos might be removed, especially weeb content.
There is a cytube that you can paste videos into and watch with whoever happens to be around. It's open submission unless there's something important to commandeer it with at the time.
A weekly watch party happens every Saturday (Sunday down under), with video nominations Saturday-Monday, voting Monday-Thursday. See the pin for whatever stage it's currently in.
Not an expert but
In the first place, mitochondrial dna are shared among many people, for the basic fact that it is passed matrilineally. This allows us to prove the existence of the so-called Mitochondrial Eve, to whom all humans alive today are related.
Second, the mitochondrial dna encodes basically the production of ATP. Not genes that would be used to express any apparent difference between people.
Third, the number of base pairs in mitochondrial dna is very small, tens of thousands, compared to the 3.1 billion base pairs in nuclear dna.
