PPT-Meiosis Progress indicators

Good progress Describe how sexual reproduction results in genetic variation Draw diagrams to explain how gametes are formed in meiosis Outstanding progress Explain the number of chromosomes in the gametes during meiosis and fertilisation . 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 (. 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.. 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. Gametes. ________ are sex cells. . Haploid. 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?. 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 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.
