Meiosis Modeling Activity

Background Information Meiosis is the process by which eukaryotic organisms produce egg and sperm having half the genetic information (haploid) of the other cells in the organism’s body (diploid). You will notice some similarities to mitosis but some definite differences in meiosis that result in genetic diversity in the gametes as well as the offspring formed by the eventual fusion of the egg and sperm. Two of the most noted differences in meiosis are that 1) there are two complete divisions resulting in four daughter cells and, 2) meiosis has crossing over, an even that occurs in Prophase I that increases genetic variation in the gametes. Crossing over occurs between homologous chromosomes. These are the pairs of chromosomes in an…
