Let me state here and now that I am not a geneticist nor do I claim to be an expert on this subject. I have, however, done a great deal of reading on the subject and used and studied it in my years of breeding Great Danes. Once the basic principles are learned and understood, it becomes an invaluable tool to breed improvement. It helps you to understand why certain traits that were not seen in the conformation of the parents can turn up in the conformation of the offspring. You no longer feel as if you are groping blindly in the dark in your quest to improve your dogs.
I do not intend to delve too deeply into how the sperm and ovum carry the genes or the mechanics of microscopic reproduction. This subject can be learned from many good texts written for the layman in comprehensible terms. If you have little or no knowledge of these facts, you should learn your basics as it will give you a better understanding of the information contained in this section. I have included my own basic descriptions in that, without some knowledge of reproduction, you will not understand the following concepts. Mainly I intend to explain how genetic understanding can be used to accomplish your breeding goals and how I use it.
