16. Prophase I
16. Metaphase I
16. Anaphase II
17. Interphase
• Interphase (technically not part of meiosis,
you’re right!)
17. Telophase II and Cytokinesis
18. The diagram shows
Crossing over
19. It occurs during
Prophase I of meiosis

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
23.
• If the diploid number of chromosomes for an
organism is 16, each daughter cell after
mitosis will contain __16__ chromosomes.
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
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)
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
27.
• While a haploid number of chromosomes may
be even or odd, a diploid number is always
even.
