Yes, that's true, but the mitochondrial DNA only has the genes encoding proteins involved in the mitochondrial metabolism, and not all of them even. So mitochondrial DNA is great for genetical studies on evolution, population biology, speciation etc., but the DNA itself does not do much about the individual characteristics and absolutely nothing about the genetical variability of the population, it actually includes some of the most conserved genes there are - those are genes that are least changed as time goes and are very similar even in very unrelated species.

I forgot to add - there are of course regions of mitochondrial DNA that change quite rapidly, so can be different even between the individuals of the same species, or races or even families maybe, but those are non-coding regions, not the genes.

Oh, definitely!! The studies are not in the least conclusive..just exciting research on the differences on the inheritance of male and female genetics. Would definitely like to see if there are any other differences.

Just fascinating. I have a bitch (GSD) that throws her temperament every time regardless of the male. Same with size all her pups are large. Ive tried to carefully select studs with the genetic make up to get smaller animals but never had any luck.
