Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Male bees and other Hymenoptera, for example, are monoploid.

Place the beef on a rack in a shallow roasting pan with the fat side up. Do not cover the roast and do not add any liquid (liquid is used for braising, not roasting). Allow the beef to roast at 450Â°F for 45 minutes and then begin checking the internal temperature of the meat with a meat thermometer.Continue roasting the meat until the internal temperature has reached 5 or 10 degrees below the desired doneness.enerally, the roasting time may range from 15 to 30 minutes per pound. The 2Â½ pound, bottom round roast pictured on the right, required 55 minutes cooking time to reach the desired doneness, which in this case is medium rare to medium.
