The sugar is one of the exotic small pets. I would hazard a guess that far higher rates of neonatal death or deformity occurs in units where closely related animals are being bred than in those where heterosis is achieved or the breeder makes concerted efforts to outsource unrelated bloodlines on a regular basis and pays close attention to detail where pedigree or ancestry of the animals in their care are concerned.
Perbedaan antara jantan dan betina adalah pada betina tubuh dan kepala lebih kecil dari pada yang jantan serat mata pada betina sayu dan sorotnya lemah, sedangkan pada jantan mata menonjol dan sorot mata tajam penyebaran burung ini di kawasan Asia Tenggara.
The reason I have used the above examples to briefly explain the concepts, logic, benefits and costs of inbreeding in general in food animals and domestic pets is that the majority of scientific study to date on inbreeding and artificial selection effects is in these fields.
Exotic cat ownership is already regulated by the U.S. Department of Agriculture, the U.S. Department of Interior, the U.S. Fish and Wildlife Service, CITES, the Animal Welfare Act, the Endangered Species Act, the Lacey Act, more city, county, and state regulations than you can shake a stick at, as well as existing animal welfare and public safety laws that govern both exotic and domestic animals.
Perhaps more visible than food animal costs of inbreeding or line breeding over time are the massive array of genetic health problems affecting pedigree dogs due to generations of close matings required to establish certain breeds from a small genetic pool of similar ancestors.
