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 . 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 . Chapter 12. Outline. Introduction. Asexual. Sexual Reproduction. The Phases of Meiosis. Division I. Division II. Alternation . of Generations. Introduction. Asexual . Reproduction . - . p. roduction . 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 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. . Image from about.com . meiosis_metaphase_1.jpg. . Mutations. (changes in an organism’s DNA) are the . original. . source of . all. genetic variation. Mutations create different versions of genes called . 1. Introductory Vocabulary. 2. Heredity. .  . t. he . transmission of traits from one generation to the next . Variation. .  when o. ffspring . differ somewhat from their parents and . siblings. Variations on a Theme. Living organisms are distinguished by their ability to reproduce their own kind. Heredity . is the transmission of traits from one generation to the next. Variation . is demonstrated by the differences in appearance that offspring show from parents and siblings. 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. Interphase. Cytokinesis. Telophase. Anaphase. Metaphase. Prophase. Mitosis. Meiosis. What looks similar between mitosis and meiosis?. What looks different?. Vocabulary- Meiosis. Process of reduction . Learning objective This learning material is about the life cycle of a cell and the series of stages by which genetic materials are duplicated and partitioned to produce two daughter cells with the These phenomena observed in Saccharomyces cerevisiae are highly conserved in eukaryotes, thus rendering yeast, which is easy to use, an essential model organism. Researchers identified and studied fun 1 identify the stages of meiosis. Only diploid cells caages of meiosis in a diploid cell where 2N = 6Meiosis involves 2 consecutive cell divisions. Since the DNA is duplicated result is 4 haploid cel Levels of Biological organization. Cells  Tissues. Tissues  Organs. Organs  Organ Systems. Organ Systems  Organisms . From zygote to Trillions of Cells. Zygote=Cell that forms when sperm and egg join.
