It’s my understanding that the vax alters the dna within the mitochondria, which are the little organelles in each cell that store energy. The mitos also carry the genetic imprint for the female lineage, thus what us known as mtDNA within genetic testing circles. This chart is super-simplified, as it appears to indicate the daughter will not inherit any other dna, which is obviously not true. There is also autosomal dna, which you inherit from many different ancestors, but it becomes so diluted that it is more difficult to trace beyond 6 generations, where as YDNA can take a perfect snapshot all the way to your ancestor of origin.
