Do you really think a gene that might be aproblem knows whether or not it is in a purebred or a crossbreed?
Read about how a new breed was recognized by the AKC or the Canadian Kennel Club in Canada that was the result of mixing breeds, IT was not by throwing some breeds together calling them something and suddenly they are a purebred. |
We had been discussing this on the previous page, if you see what is written there, I had agreed with the statement that says.
"A dog hybrid is the offspring of parents of two different purebred dog breeds, more commonly called a crossbreed or crossbred in animal breeding. Crossbreeding (parents of two different purebred breeds) results in offspring that may be stronger and healthier than either parent, an effect called hybrid vigor, but only if both parents are genetically sound."
Some experts do believe there is a phenomenon called hybrid vigor; unfortunately it is not always there, so it is not predictable.

That little word "may" is extremely important, it is not the same as saying "will." Also notice the other words in bold, "but only if both parents are genetically sound. So in other words this hybrid vigor MAY occur, but ONLY if the parents are genetically sound. People who mix breed seldom test for genetic problems. Also, notice the statement, " that this advantage is lost when the two hybrids are bred in an attempt to create a breed," this means that as soon as the breeder attempts to breed the offspring again, the advantage of hybrid vigor is lost. |
I was originally responding to post 353, so you might want to read that too for further clarification on this issue.
