Meiosis is the cell division which produces the . sex cells . or . gametes. .. Meiosis occurs in the cells of the . reproductive organs. :. Sperm cells – testes. Ova (eggs) – ovaries. Pollen - anthers. The . disadvantages and advantages of sexual . reproduction. CfE. . Advanced Higher Biology. Unit . 2: . Organisms and Evolution. SQA mandatory key information. Disadvantages of sexual reproduction – males unable to produce offspring, only half of each parent’s genome passed onto offspring. Benefits outweigh disadvantages due to increase in genetic variation in the population. . 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. ch. : 7. Sexual or Asexual. Asexual – involves a single parent organism and produces off-spring or daughter cells that are clones. Sexual Reproduction – involves genetic contribution in the form of gametes from two sources. Mrs. Stewart. Biology I . Stewarts Creek High School. Objectives:. Differentiate between the process of mitosis and meiosis. Demonstrate the movement of chromosomes throughout meiosis. Analyze how meiosis leads to genetic variation. Chapter . 11. Genes and Development. Fig. 11.1. Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display.. Haploid sperm. Haploid egg. Diploid zygote. Fertilization. Meiosis Terms . to Know:. Meiosis. : Cell division that produces gametes (sex cells/sperm & egg). These cells are used for sexual reproduction. They have . half . the number of chromosomes as the parent cell.. 1. Asexual Reproduction. Requires only one parent. Offspring have 100% the same chromosomes as the parent.. In other words, the offspring are exact “clones” of the parent.. 2. Asexual Reproduction. © Copyright 2015 – all rights reserved . www.cpalms.org. How do Sexual and Asexual Reproduction compare?. DNA transfer through . sexual. reproduction (meiosis) and . asexual. reproduction (mitosis) equip organisms in different ways for survival. Asexual reproduction: Overview. Example #1: . Garlic (. Allium sativum. ) . “As far as we know, garlic in cultivation throughout history has only been propagated asexually by way of vegetative cloves, bulbs, and bulbils (or topsets), not from seed. These asexually propagated, genetically distinct selections of garlic we cultivate are more generally called "clones". Yet this asexual lifestyle of cultivated garlic forgoes the possibility of combining traits proffered by interpollinating diverse parental stocks.”. Meiosis is the. . type of . cell division by which . germ cells . (eggs and sperm) . are produced. . One parent cell produces . four . daughter cells. . Daughter cells have half the number of chromosomes found in the parent cell. Let’s Review!. The cell cycle is when . a cell makes a copy of itself . for:. Growth, Repair, Replacement.
