Along with crossing over, independent assortment increases genetic diversity by producing novel genetic combinations. Of the 46 chromosomes in a normal diploid human cell, half are maternally derived (from the mother's egg) and half are paternally derived (from the father's sperm).
Q. I recently started my dog on Rimadyl for his arthritis and he is like a new dog, almost like a puppy. Is there a version of this medication for humans? A. Rimadyl (carprofen) was prescribed for humans between 1988 and 1998. In the U.S., it is now exclusively approved for dogs. Rimadyl is a nonsteroidal anti-inflammatory drug (NSAID) a bit like celecoxib (Celebrex), ibuprofen (Advil, Motrin) or naproxen (Aleve). Like all NSAIDs, Rimadyl can cause life-threatening ulcers as well as liver and kidney toxicity. You might get relief from your own joint pain with an NSAID approved for humans.
Human nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen are felt to be too toxic for safe use in pets at ANY dose. Common dog-specific NSAIDs include carprofen (Rimadyl, Vetprofen), meloxicam (Metacam), and deracoxib (Deramaxx).
