Mitosis can occur in a diploid nucleus, that is, one containing pairs of chromosomes representing each of its parents or in a haploid one containing a single set of chromosomes. Meiosis, often called reduction division, yields four daughter nuclei with the number of chromosomes reduced to half the original number. The overall result is that one diploid nucleus becomes four haploid nuclei.

In 1997 astronomers suggested that Aldebaran is orbited by another body about twelve times as massive as Jupiter with a period of two years. This object would lie in the fuzzy boundary between giant planets and brown dwarf stars.ften represented as the bullâs eye, Aldebaran (or Alpha Tauri) lies 65 light years from Earth, right in front of the Hyades cluster (which is about 70 light years further from us). A K5 III red giant about 350 times as luminous as our Sun, it appears as a red-orange magnitude 0.9 object in our sky.
