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, despite being relatively small, stood out in its ability to design robots that offer a highly interactive experience. Aldebaranâs flagship robot is a knee-high humanoid called Nao. More than 6,000 Naos are now used in research labs, schools, and hospitals in 70 countries.
