Document Summary
Pre reading: chapter 9, sections 9. 1 and 9. 3. Read 9. 1 but just review the end of chapter summary for 9. 3 and take a good look at figs. Independent study outcomes: products of meiosis in animals vs. plants, fungi and algae, timing of meiosis in vertebrate life cycles, main differences between meiosis and mitosis, characteristics of homologous chromosomes. That is, how can you inherit mutations on both homologues of chromosome 6 but give a chromosome 6 with no mutations to your offspring? mechanism by which errors in mi or mii give rise to aneuploid products of meiosis. Mistakes in meiosis are survivable, but can produce sever developmental abnormalities. Mitosis vs. meiosis in eukaryotes, mitosis produces two genetically identical daughter cells from each parent cell in organisms that reproduce asexually, mitosis produces genetically identical offspring. Meiosis produces daughter cells that are genetically distinct from, and contain half as much dna as their parent cells.
