Blitzen OMG LOL. Buy a book on gentics and read it. I am done here. 

Which book would you recommend, Hans? One that explains the mode of dominant inheritance. 

Jemi so what is your point?I agree with you so now what?

To be denying practicality of a fact  that breeding  in male line generates predictability and uniformity  is denying facts which are well established but  not known to ignorant and not learned by lazy.  That is an attitude which in specificity and in general is in part what causes  demise of the breed. 

So according to what you type, Rolf originated missing testicles....there was never a dog, in any breed ( because we have been taught that many breeds were use to create the gsd) that ever had a missing testicle or produced missing testicles, before Rolf was born? Pretty amazing, and even more amazing is how was that 'knowledge/information/fact' acquired? BTW, cryptorchidism is autosomal ressessive and takes both parents for it to be expressed in offspring. So your bs that it is expressed magically ten generations from only ingo doesn't stand up to science, because you now say 'stud line' 'aka male line' which would exclude any females related to Rolf. Appearantly you are trying to reference the 'male tail line' ? Read jemi's post above....they nailed it.

If I breed your super male to a crap female what am I likely to get? Super crappy dogs?

Laws Behind the Genetics of Dog Breeding

Genes come in pairs

Genes are like a program that determines an individual’s appearance and behavior. They are strung together like a paired string of beads to form chromosomes.

To make a pair, you get one gene from mom and one gene from dad

Each of a dog’s cells (except sex cells) contains two strands of chromosomes, one from the father and one from the mother. Sex cells (sperm and eggs) have only one strand of chromosomes.

At fertilization, a sperm and an egg join to form an embryo in which the chromosomes inherited from the two parents are again joined into pairs.

What you see is the result of genes

The genes that are paired along the chromosomes determine the traits of the offspring – what it looks like, and even how it behaves.

However, not all genes that are inherited can be seen in the offspring

An individual may inherit genes that are:

• Unalike in the pairs, in which case one usually “dominates” the other, so that the dominant one shows up in the characteristics of the puppy, and the recessive one is unexpressed and hidden.

• The genes may be identical and code for the same trait, which will then be expressed in the offspring unopposed.

 

Monorchids and cryptorchids are all about when the inguinal ring closes and where both testicles are at that time. If  both are above the ring  at the time of closure, the dog will be a cryptorchid. If one is above, one below, the dog will be a monorchid. A testicle can also be trapped in the ring when it closes. Some think the ring should close a few days after birth while others think a delay is normal. Most agree that an older puppy with "bobbing" testicles may not be good breeding risk due to the delay in the closure of the ring. A 5, 6 months old male that has both testicles in the scrotum one day, and none or only one the next should probably not be used for breeding if one is trying to elminate that fault in their breeding stock. Selective breeding should reduce the chance of that happening.

prager, what the point is?  The point is that the future of any breed lies on proper selection, not primarily on facts that this or that dog is son, grandson, or great grandson of some famous dog, recognized by some famous organizations.  And a little knowledge of genetics may help.
