What is the importance of meiosis in providing genetic variation?. . SPECIALIZED CELLS. You have many specialized cells in your body that can be divided into two groups. . 1. . . SOMATIC. = body cells; make up most of your . Dr. . Debbie Payne, Ruth H. Liddell, Shirley K. Scarbrough. Alabama State University, Math, Science Partnership, . Summer 2013. CROSSING OVER. When does it occur?. Why is it important?. Meiosis in Lily. Reduction Division. Mike Clark, M.D.. Meiosis. Meiosis is nicknamed reduction division. It is a process where a cell divides (division) but reduces the genetic material to ½ (reduction) . This type of cell division occurs in the gametes (sex cells). IB Biology. Cell Cycle. Mitosis. Prophase . Metaphase. Anaphase. Telophase. Lung Cancer. Meiosis. Mitosis vs. Meiosis. Crossover . Karyotype. Trisomy. Monosomy. Meiosis. The process that produces haploid sex cells.. Cells go through 2 rounds of division, called meiosis I and meiosis II. Each division has 4 phases (. similar to . mitosis). Creates 4 haploid cells from 1 diploid cell. Gametes. ________ are sex cells. . Haploid. The daughter cells produced at the end of meiosis II are considered- diploid or haploid?. Genetically DIFFERENT!. What is the genetic relationship of daughter cells to each other in meiosis?. Please take out your science journal and outcomes and turn in any missing work to the WIRE basket. Thank you!. . Asexual Reproduction Review. Happens in almost all cells (Somatic cells). 1 parent cell. Chapter 10. Overview of Meiosis. 10.1. Overview of Meiosis. Meiosis. - type of nuclear division that reduces the chromosome number from the diploid number to the haploid number.. Gametes. - reproductive cells. Mistakes in Meiosis. Many genetic disorders can be traced back to . errors in formation of the gametes . in meiosis. Could occur as the result of:. Mistakes in . separation of the chromosomes . during division. Yvonne Norman. Edited By: . Ms. . Ethridge. , Ms. Myers, Ms. . Milstead. , and Ms. Palermo. Objectives. Define mitosis.. Define meiosis..
