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.
We are not so different when it comes to genes either. The dog genome is basically the human genome divided into about 70 different pieces and rearranged on a greater number of chromosomes, according to a new map of the dog genome. While making the map, the researchers lined up each chromosome segment in the dog with its corresponding region of the human genome.
