gametes Meiosis produces gametes Meiosis was first observed by the Belgian cytologist PierreJoseph van Beneden in 1887 60 years before we knew that DNA contained the genetic material Gametes. EQ:. 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 . Each organism must inherit a single copy of every gene from each of its “parents.”. Gametes. are formed by a process that separates the two sets of genes so that each gamete ends up with just one set.. http://www.youtube.com/watch?v=lJzZ7p-47P8&feature=related. . State that meiosis is a reduction division of a diploid nucleus to form a haploid . nulcei. .. Define homologous chromosomes. Outline the process of meiosis, including pairing of homologous chromosomes and crossing over, followed by two divisions, which . (making sperm and eggs…). We. ’. re NOT talking about making babies, we. ’. re talking about making the CELLS that make babies – eggs and sperm! . Eggs and sperm are GAMETES.. Gamete = sex cells (. Take out a piece of paper and write for two minutes what makes you unique . . Human. Cat. Shrimp. Bean. Before Meiosis. Chromosome. number (haploid or diploid?. 46. ?. ?. ?. Number of pairs of homologous. Sexual Reproduction. SEXUAL REPRODUCTION. Sex cells formed by meiosis. Requires 2 parents. Offspring not identical. The process that results in the formation of . gametes. Sex cells, egg or sperm, which have . 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. Alleles segregate during meiosis allowing new combinations to be formed by the fusion of gametes. . Understandings:. One diploid nucleus divides by meiosis to produce four haploid nuclei. . The halving of the chromosome number allows a sexual life cycle with fusion of gametes. . 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.. Analyze function of mitosis and meiosis in cell differentiation.. 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.. Key Concepts:. What happens during the process of meiosis?. How is meiosis different from mitosis?. Types of . Reproduction. Section 11-4. ASEXUAL. SEXUAL. 1. One Parent. 2. Binary fission (in prokaryotes) or mitosis in (eukaryotes).. DON. ’. T EAT THE CANDY!!!!!! . Yet. Om nom nom.. Lab Procedure. You will be doing a lab which will take you through the phases of . Meiosis, using the candy as parts of the cell!. ! . What are the phases of Meiosis?. 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.
