Good Looking Pups, and appear to be fireballs. I have often read where folks say the female has more influence on pups because she carries and nurses them, I consider that to be an environmental influence and to be almost completely false. If weaned at an appropriate time she will not have any more influence than any other dog they are closely associated with. Buuuut all mammals receive their mitochondrial dna from their mother only, so if there are any performance traits attached to the mitochondrial dna they are passed to the offspring only from her which could give the female an advantage. All that I have ever been able to find out seems that the mitochondrial dna is more closely associated with health issues be they good or bad.
Clue, from what I've found on the genetic material that's carried and passed through mtDNA, has a lot to do with muscle control and function, which correlates into athleticism, and working abilities, and it got into a little more detail about a few certain other genes dealing with health, that's a lot of reason why the race horse people and bird dog world has put a lot of emphasis on the females lineage, I'll see if I can find that study again and post the link...
Secretariat is one of the sires that was involved in a study done by the race industry as to why such on prominent stallion couldn't reproduce a son as equal to or greater than himself, it was discovered that his daughters carried the genes to produce good stallions as equal to their grandsire....
