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 . 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 . Dr. . Debbie Payne, Ruth H. Liddell, Shirley K. Scarbrough. Alabama State University, Math, Science Partnership, . Summer 2013. CROSSING OVER.

Homologous chromosomes. 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.. IB Biology. Cell Cycle. Mitosis. Prophase . Metaphase. Anaphase.

The daughter cells produced at the end of meiosis II are considered- diploid or haploid?. Genetically DIFFERENT!. What is the genetic relationship of daughter cells to each other in meiosis?. 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. 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. . 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:.
