Without looking at an entire pedigree going back at least 6 generations
will tell you more about your pigeons than we care to divulge.
There are formulas out there where you can input the data and it will
give you an exact percentage of inbreeding which is called "Inbreeding
Coefficient". This data shows many things and when we say we have a
highly inbred family that has done such and such, the inbreeding
coefficient number will put a number to exactly how inbred a pigeon is
supposed to be. This number takes into consideration all the pigeons in
the background for as far as we have data and does not just look at one
or two pigeons which we think are key.
Now, unless we have all individual breeding sections to guarantee the
purity of the mating, there can always be other surprises. However, when
we put a number to something, it only tells us what is theoretical as
although a pigeon gives 50% of it's genes to it's offspring, which 50%
did it give?? Remember that pigeon got 50% of it's genes from each of
it's parents so we never really know which gene it gives to it's baby.
If it was always the same one, then all it's children should look
similar but they don't. The combinations the babies can receive from
their 2 parents total into a number we can not even care to try to
calculate.
There are many ways to develop a family and I used to practice the same
inbreeding principles we hear about today but eventually one must go to
the outside to bring something in or they reach a point of inbreeding
depression or bottlenecking. The choice is ours as to what we follow and
I chose to not inbred IF POSSIBLE!! The problem is if we keep bringing
in the same pigeons from the same source, then soon we are backed into
the corner and need some blood to freshen the mix.
The choice is yours and as I already admitted, I followed those
inbreeding examples and styles and was not happy with the final results.
This is my opinion and it seems to be agreed upon by all the institutes
of health or we would see people being allowed to marry their sisters or
have children with their mother or father. This is against the law in my
country so why aren't these types of marriages allowed.
Hope this helps,
Bob Rowland
