5. During
meiosis, the chromosome number:
a) is doubled b)
is reduced c)
remains the same d)
becomes diploid
6. Cells starting mitosis & meiosis begin with a
(haploid or diploid) set of chromosomes.

_______
8. What are the stages of meiosis called?
Meiosis I: _________________,
_____________________, _________________, ____________________/cytokinesis
Meiosis II: _________________,
_____________________, _________________, ____________________/cytokinesis
9. Draw a tetrad:
What phase do you first see this in?
Figure 2

An
exchange of information between two homologous chromosomes

12. Which letter in figure #2 represents meiosis? Why?
13. Which letter in figure #2 represents mitosis? Why?
14. Is DNA copied before Meiosis II? _______
15. How many cells form at the end of Meiosis II and
how many chromosomes do they contain? _____________, _____________
16.A
sperm cell is a (gamete, zygote), and is (haploid, diploid).
17.When
a sperm cell and an ovum/egg merge, they undergo the process of fertilization,
and give rise to a (gamete, zygote), which is (haploid, diploid).
18. What is the ultimate goal/purpose of mitosis? What
term do we use to describe the new cells?
19.. What is the difference between chromosomes,
chromatids?
20. How are DNA and chromosomes related?

and zygote?
Haploid:
Diploid:
Zygote:

chromosome number: 2n or n?
25. What is crossing over? When does it happen? Draw a
picture if it helps.
