Meiosis in Cell Division

Grade 1145 min

aligned to Explain The Function Of Meiosis In Sexual Reproduction. Distinguish Between Somatic Cells, Germ-cell, And Gametes; Also Between Autosomes And Sex Chromosomes. Describe The Stages Of Meiosis And Include A Description Of How Homologous Chromosomes Pair During Prophase I, And The Behavior Of Chromosomes Through Both Meiotic Divisions. Explain Why Meiosis I Is Called A Reductional Division And Meiosis Ii Is Called An Equational Division. Compare And Contrast Mitosis And Meiosis. Explain How Crossing Over, Independent Assortment Of Homologous Chromosomes, And Random Fertilization Account For An Increase In Genetic Variation. Describe The Technique Of Karyotyping And The Uses For It. Explain How Nondisjunction Could Result In An Altered Number Of Chromosomes And Describe Alterations In Chromosome Structure That May Occur.

Learning Objective
