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.

Alkenes are also called olefins. Like alkanes, this can be confusing because there is also an olefin material. As in the case of paraffin wax and alkanes, olefin is just a type of fiber that is made from alkenes.Olefin is often made from polypropylene or polyethylene and is used in everything from rope to car interiors.ike alkanes, this can be confusing because there is also an olefin material.
