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. 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.. Homologous chromosomes . – identical chromosomes. . …same length, . centromere. , same staining pattern. . …exception…males sex chromosome. 1-22 . autosomes. . sex . chromsomes. Homologous chromosomes. 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). Chromosome number. Phases of meiosis. Meiosis and genetics. Gamete formation. Comparing mitosis and meiosis. Chromosome number. A cell in adult . drosphilia. (fruit fly) has 8 chromosomes, 4 of which came from the fly’s male parent, and 4 of which came from the fly’s female parent.. 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. 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 Life Cycles. Which of the following transmits genes from both parents to child, or from one generation of a family to another?. DNA. gametes. somatic cells. mitosis. nucleotides. Which of the following transmits genes from both parents to child, or from one generation of a family to another?. 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 8. Asexual vs. Sexual reproduction. Asexual reproduction – new organisms/cells are genetically identical to parent cells/organisms . Sexual reproduction – offspring have a combination of genes from both parents. . 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. 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).. 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.
