CzW ownership in Sweden

When a wolf/dog breeding programme is terminated, ending with the F5
generation, how do interbreeding withtin the same F-generation result in
generations of a higher F-number?

I am not sure how they do things in Europe (that is why I am here, to learn
but in the USA they divide the % by 1/2 .. in other words, if the
"wolfdog" is only an F3 he would be considered 12.5% and if bred to a dog,
the pups would be 6.25 or F4 but if he was bred to and F4, then you would add
the 6.25 and the 12.5 to total 18.75 since any breeding only gets "half" from
each parent, they would then divide this by half to state that the pups are
only 9.37 (less then 10%) but could be as high as 18.75 if they inherited
more "wolf blood" from their parents. So in other words .. there is no exact
% for each pup .. one could be only 5% while his littermate is 15% (in
reality)
as to the F factor, this would be difficult to analyze if you want to be very
accurate.
