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.
Of the thousands of genes in the genome (dogs have about 19,000, compared to humansâ approximately 23,000), an inordinate number are involved in communicating with one another, sending information that either activates or represses a âdimmer switchâ in other genes.ogs come in countless shapes and sizes and exhibit more diversity than any other land mammal on earth, a fact that makes them especially appealing to geneticists.
