The reduction in chromosome number occurs during <u>meiosis I.</u>
Chromosomes are long molecules of DNA that contain some or all of an organism's genetic material. In most chromosomes, very long, thin strands of DNA are coated with packaging proteins. In eukaryotic cells, the histones are the most important of these proteins.
Within the nucleus of all cells, DNA molecules are packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly wrapped many times around proteins called histones that support its structure.
Another type of cell division, meiosis, ensures that humans have the same number of chromosomes from generation to generation. This is a two-step process in which the number of chromosomes is halved from 46 to 23 to form sperm and eggs.
