The parents genotype must have been half fainting half regular and the other parent had to be the same way. The parents would not have fainted because they had the non fainting gene.
If two different species reproduce and have children, then these children will not be fertile. E.g, when a horse and donkey reproduce together, then the offspring is called a mule. The mule will always be infertile, as will the offspring produced by cross-breeding of species. If two different breeds reproduce, then the offspring should share the characteristics from both breeds.
Basically a crossbreed
Inbreeding is the breeding of closely related individuals of a species generally to produce more uniform offspring. Hybridization is the breeding of different varieties (breeds) or even different species to increase variation/ vigor in the genetic population. An example of variety hybridization would Labradoodles (labrador X poodle). An example of species hybridization would be (wolf X coyote). Many offspring produced from species hybridization are sterile... depending on the chromosome number compatibility and other factors.
Cross breeds usually carry the genetic traits of both parents. Meaning, if you mate a breed that is known for high milk producing females with another breed that is known for high meat production, then you will get an offspring that excels both traits. Whereas, purebred off spring will throw that breed characteristic.
To get a purebred bovine (not necessarily a cow), you have to do a lot of breeding-up in order to have your cows and bulls producing the same type of offspring that their parents are. This takes years and years of work to do, and is much harder for one person to do than it does for several people to do. How it's done is that you select the best quality bull that has all the traits that you want your new breed to have. Then you find a cow of another breed and breed that cow with that bull to get the calf you are wanting to use to start breeding up to produce offspring that are to be recognized as a separate breed and not just a crossbred. Then you can throw in one or two (or even more) breeds into the mix to get the type of breed you want. You have to keep doing this with the breeds you've selected and the offspring you've ended up with (making sure you cull out the undesirable or inferior offspring, cows and bulls) until you find you are getting more uniformity in the herd, and not just a herd of mutt-cattle. After getting others interested and helping with the breeding-up program and after another 10 or 20 or even 50 years of consecutive breeding-up and trait selection, naming the breed you've created and getting recognized by the national breeds council and what-not, you have your breed.
No. Roosters and hens can be of different breeds to create offspring, just like different breeds of cattle, sheep, goats and pigs can breed to create offspring.

Depends on the pedigree. If the parents to the pup were good hunters chances are their offspring would be too. I have heard from many freinds they are one of the most difficult breeds to house break.

They are simply two different breeds, originating from different parents and other breeds. They have different bloodlines.
Hybrid hybrids. Completely infertileand won't live very long.
an animal with purebred parents of two different breeds.
Yes, and no. Some goats can have up to six offspring. It all depends on the goat really. Larger breeds tend to bear more young, especially the dairy breeds.
A deer and a rabbit are completely different species and cannot interbreed, but the imaginary offspring is called a 'Jackalope'.
They will be fertile. They are the same species, just different breeds.
