3.2 Meiosis
Across
- 5. the division of cells after meiosis the forms to daughter cells
- 7. the 23 pairs of homologous chromosomes are aligned along the equatorial plate
- 8. reproductive cell
- 10. when an egg containing 23 chromosomes and a sperm containing 23 chromosomes unite to form a zygote containing 46 chromosomes the process is called
- 12. when two chromosomes pair up and exchange segments of their genetic materials during meiosis
- 13. a cell that has one set of chromosomes
- 14. the stage where a cell grows and matures to prepare for division
- 16. having the same structure or shared ancestry
- 17. fertilization between two haploid cells
- 18. this process occurs during meiosis when two homologous chromosomes pair
- 19. cell division that is necessary for sexual reproduction
Down
- 1. spindle fibers attach to centromeres when sister chromosomes separate
- 2. the original cells that make up the ovaries
- 3. cells that are located in the male testis that produce sperm cells
- 4. an organized package of DNA
- 6. containing two sets of chromosomes
- 9. a method of asexual reproduction
- 11. cytokinesis takes place during this stage marking the end of the fist division of nuclear material
- 15. chromosomes become more condensed and can be viewed under a microscope
