The carrier genes must be somewhere on BOTH sides for this to throw forward,usually parti bred to parti SHOULD produce all parti BUT since this was a gene that was produced from a normal colored Yorkie,this IS a chance someone could produce a puppy with a little more Yorkie color and less white somewhere down the line....lines for color must be reinforced,if the gene pool is limited,( in the surrounding area)be careful of inbreeding.
There is great discussion on "who contributes what" some will say it "is the stud who sets the litter" I believe it must take both,sire and dam,with qualities and faults from both to contribute to a litter. This does not mean you do not search for the best quality,healthy sire( if you do not have your own) every bitch can get some excellent qualities from studs,darker eyes,better ear sets,size,conformation,smaller ears,good hips,good knees, no liver shunt problems>>>BUT>>> the bitch must also be free of health problems
and she will still give her 2 cents worth in all the puppies born.If not, IF it were just the stud who gives everything to the litter,we'd see 100% exact
duplicates,a "perfect clone" of only the stud... don'tcha think?
So,BOTH of these dogs MUST carry this color gene somewhere in the back-
ground,could be as far back as the 5th generation,could be further back than this BUT IT IS THERE.
IF you are not breeding for health AND JUST A SPACIFIC COLOR, it can be a hit and miss if another parti is born,it could happen once more,it could then stop or it could continue to have one or two born..not knowing the genes and colors behind...unfortunate but there is no guarantee.
Our beautiful Biewers are an example of breeding for health AND COLOR and this was over many generations and YEARS OF HARD WORK,to breed these little wonders!Someone had to do a lot of genetic reseach...again...even IF both parents carry this parti gene..to establish it,will take YEARS OF CAREFUL BREEDING to set and establish the colors as well as maintain health. |
