The underlying genetics of cross breeding
The involvement of man in dog breeding and the drive to produce the hundreds of purebreds has produced one significant downside: a large number of health problems that has serious impact on both the body and behavior of these purebreds.
The breeding method (selective breeding) that is at the heart of producing purebreds also means that some unwanted traits and genes will be passed down the bloodline. This also means that even rare and unwanted genes like those that cause health problems will not only stay in the bloodline but their frequency will increase resulting in more dogs within the breed suffering from those health problems.
Health problems in dogs could be caused by recessive genes or dominant genes and because genes occur in pairs a pup can only suffer from a health problem caused by recessive genes if it inherits a recessive gene from both parents to form a pair.
On the other hand, pups only need to inherit a single dominant gene from either parent in order to suffer from a genetic health problem.
When purebreds like the German shepherd and the husky are crossed(Gerberian Shepsky) the pups cannot suffer from the parent breed health problems that are caused by recessive genes. Since the offspring of the cross breed can only have one of the recessive genes or nor at all.
This will eliminate a large number of genetic health problems that are caused by recessive genes particularly when dealing with a breed like the German shepherd that suffer from a large array of health problems. However health problems that are due to dominant genes can still be passed down the bloodline since only one of the gene pair of a dominant gene is required for the offspring to suffer from the health problem.
