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.

Aldebaran, Alpha Tauri, also known as the Eye of Taurus, is an orange giant star located at a distance of 65 light years from Earth in the direction of Taurus constellation.ldebaran is very easy to find in the sky. To locate the star, observers can just follow the line formed by the three stars of Orionâs Belt to the right (in northern latitudes) or to the left (in the southern hemisphere). Aldebaran is the first bright star that appears along that line.
