...to start reading this article from the beginning please click on here...The final step is the mating of the half brothers and half sisters to set the traits, which are produced by mating the single foundation sire with the two foundation females. The result of the half brother and half sister mating will be the third generation with the resulting offspring being double grandsons and double granddaughters of the superior male and founded off of your superior females which also happen to be bred down from the ultimate germ-line dam. From this population, we will have now produced a handful of dogs that may match or exceed the quality of the ancestors and set a few new and desirable traits. Note however you have reached what is known as a high inbreeding coefficient in your final product animals. We shall see below that the IC is an important measure of how tightly bred our germline is. Thus we have seen a basic and logical 3 generation line breeding program now however the IC indicates that for our program to continue we must choose to outcross or outreach (distant relatives but still within the lines) to avoid inbreeding depression. NOTE: One must not try to line breed to more than one common ancestor except as noted above using a niece for example of your original bitch. The double grandsons and granddaughters will be genetic sons and daughters of the foundation sire. Close line breeding is inbreeding even if it is not mother/son, father/daughter etc. Inbreeding is most appropriately defined by the COI (coefficient of inbreeding) which we do not ever want to exceed 35-50% depending on how perfect genetically our bloodline is...to continue reading this article please click on here...
