Natural abortions are typically called miscarriages. Medically-induced abortions, which can be completed with surgery or with hormone drugs, are performed because the foetus is unwanted, deformed, not likely to live, or endangers the mother's life or health.
The dog genome project is a collaborative study involving scientists at the University of California, The University of Oregon, and the Fred Hutchinson Cancer Research Center aimed at producing a map of all of the chromosomes in dogs, which can be used to map the genes causing disease and those genes controlling morphology and behavior.
The same type of DNA markers, single nucleotide polymorphisms (SNPs) are used for the cat test as for the dog tests, however the cat SNPs are unique and specific to the cat and will not cross-react with the dog. The Cat Ancestry will not work on the dog, the dog test will not work for the cat. The same type of technology is used for Cat Ancestry as the dog tests, known as MALDI-TOF (Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry).
