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.

Solid-surfacing materials--such as Corian, Wilsonart's Gibraltar and Avonite--are made of 100% acrylic, 100% polyester, or a combination of acrylic and poly. They're highly resistant to stains and scratchs, and completely renewable and repairable. Scratches and burns can be sanded out; deep gouges can be filled.
