  1. 11.4 wkbk 16-27 KEY

  2. 16. Prophase I

  3. 16. Metaphase I

  4. 16. Anaphase II

  5. 17. Interphase • Interphase (technically not part of meiosis, you’re right!)

  6. 17. Telophase II and Cytokinesis

  7. 18. The diagram shows Crossing over 19. It occurs duringProphase I of meiosis 20. The result is a newcombination of alleles/genes(Differing chromosomes)

  8. 22. • A diploid cell that enters mitosis with 16 chromosomes will divide to produce __2__ daughter cells. Each of these daughter cells will have __16__ chromosomes. • *Remember, mitosis doesn’t change the daughter cells – they’re identical to parent

  9. 23. • If the diploid number of chromosomes for an organism is 16, each daughter cell after mitosis will contain __16__ chromosomes.

  10. 24. • A diploid cell that enters meiosis with 16 chromosomes will pass through __2__ cell divisions, producing __4__ daughter cells, each with __8__ chromosomes. • Diploid cell  haploid cell • Double - half

  11. 25. • Gametes have a haploid number of chromosomes. • Half as many as a normal body cell • Ex: Humans have 46 chromosomes, except in gametes (sperm/egg) which have 23 (haploid)

  12. 26. • If an organism’s haploid number is 5, its diploid number is 10. • If given the haploid, double it • If given the diploid, halve it

  13. 27. • While a haploid number of chromosomes may be even or odd, a diploid number is always even.
