PPT-Meiosis

Reduction Division Mike Clark MD 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. 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.. (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 (. 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. 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. ?. ?. ?.

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. 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. 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. 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.. Key Concepts:. What happens during the process of meiosis?. How is meiosis different from mitosis?. Types of . Reproduction.
