Lecture 19 – Chapter 10 – Meiosis I. Mitosis vs. Meiosis A. Meiosis involves 2 successive nuclear and cytoplasmic divisions, producing up to 4 cells, while mitosis involves only one nuclear and cytoplasmic division, producing 2 cells B. Meiosis produces haploid cells while cells that undergo mitosis remain diploid or haploid 1. Meiosis maintains the correct number of chromosomes during sexual reproduction by reducing the chromosome number by half C. During meiosis, each homologous chromosome pair is shuffled, so the resulting haploid cells each have a virtually unique combination of genes. During mitosis, no such shuffling occurs, and the cells remain genetically identical to their parent cell D. There is no pairing of homologous chromosomes or crossing over during Prophase of Mitosis or Prophase II of Meiosis E. During Metaphase II of Meiosis and Metaphase of Mitosis, chromosomes line up on the midplanes of their cells F. During Anaphase II of Meiosis and Anaphase of Mitosis, chromatids (now chromosomes) separate and move toward opposite poles
