Chapter 14, Problem 11SQ
Summary Introduction
Introduction: The process of cell division includes mitosis and meiosis. Mitosis is the process of cell division in which cell splits up into two genetically identical daughter cells. Meiosis is a process of cell division during sexual reproduction where chromosome number is reduced to half. Their purpose is the formation of gametes. The homologous chromosomes randomly align with their homologs at metaphase. The chromosomes are randomly paired and segregated to opposite poles during anaphase.
