Bio#: _______ Name: ____________________________________________ Date: _____________ Hour: ________ Phases of Meiosis Complete the Table. Phase of Meiosis Description 1. Cells undergo a round of DNA replication, forming duplicate chromosomes 2. Each chromosome pairs with its corresponding homologous chromosome to form a tetrad 3. 4. 5. Spindle fibers attach to the chromosomes The fibers pull the homologous chromosomes toward opposite ends of the cell Nuclear membranes form, the cell separates into two cells 6. Meiosis I results in two haploid daughter cells, each with half the number of chromosomes as the original cell. 7. The chromosomes line up in a similar way to the metaphase stage of mitosis 8. The sister chromatids separate and move toward the opposite ends of the cell. 9. 10. Does meiosis result in the formation of Meiosis II results in four haploid daughter cells. haploid cells or diploid cells? (circle one) 11. The number of chromosomes in a gamete is represented by the symbol _____________. 12. If an organism’s diploid number is 24, what is its haploid number? ____________ 13. How many alleles for each gene does each gamete have? _____________ . 14. What process is shown in the above figure? ____________________________ ___________________ 15. When are tetrads formed during meiosis? _________________________________ 16. Unlike mitosis, which results in 2 cells, meiosis results in ______________________________________. 17. Unlike mitosis, which results in genetically identical cells, meiosis results in genetically _________________________________________ ______________. 18. A diagram showing the relative locations of each known gene on a particular chromosome is know as a _________________________ __________________. 19. Gene maps are based on the frequencies of what? _______________________________________________________________________________________ 20. What assorts independently? GENES or CHROMSOMES (circle one)
