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 duringProphase I of meiosis

20. The result is a newcombination of alleles/genes(Differing chromosomes)

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.
