Breeding for Results...

X2...I was fixing to bring up what you said but in a different way...tight family breeding with best to the best breeding from within that family will be producing consistency...so quite a bit of desirable traits are displayed because they are doubled up recessives...a recessive trait to be displayed must get one gene from each parent of the same so lets say it is for ranging and hunting...so the tight bred dogs carry those recessives for that trait but when bred to an outside dog, and that outside dog just might be carrying a dominant for not hunting and when the dominant matches up with the recessive hunting trait then the dominant trait will be displayed...so lets say quite a bit of the desirable traits in that line of dogs are paired up recessives and the outside blood has quite a bit of dominant genes for the opposite....the result will be lots of culls...but since the tight bred line has to pass a recessive and the outside dog is carrying a double dominant or a dominant recessive then some of the pups will hunt but not more than half of the litter when dealing with averages...

The biggest thing about dog genetics is that I have not seen any studies on hunting traits...
