Meiosis Quest Review
1
• The structure labeled A is called the
• Centromere
2
• The structures labeled B are called
• Sister chromatids
3
• ? are sex cells, formed by separating the
homologous chromosomes to form cells with
just one set chromosomes.
• Gametes
4
• ? is when homologous chromosomes
exchange a portion of their chromatids.
• Crossing over
5
• Cells that contain only one copy of each type
of chromosome, such as male and female sex
cells, are said to be _ ? .
• Haploid
6
• During normal mitotic cell division, a parent cell
having 6 chromosomes will produce two daughter
cells, each containing ___ chromosomes
• 6 chromosomes
7
• If an organism's diploid number is 12, its
haploid number is
• 6
8
• Are gametes haploid or diploid?
• Haploid
9
• Gametes are produced by the process of
• Meiosis
10
• Chromosomes form tetrads during which
phase of meiosis?
• Prophase I
11
• Unlike mitosis, meiosis results in the
formation of four genetically _________ cells
• Different
12
• If an organism has 16 chromosomes in each of
its egg cells, the organism's diploid number is
___________.
• 32
13
• An organism's gametes have
____________________ the number of
chromosomes found in the organism's body
cells.
• Half
14
• This is a cell in Prophase II of Meiosis II. Is it
haploid or diploid?
• Haploid
15
• Eggs and sperm are the end product of
• Meiosis
? .
16
• When homologous chromosomes find their
match, a ____________ forms.
• Tetrad
17
• What is the difference between anaphase I
and anaphase II?
• Homologous chromosomes separate in
meiosis I and sister chromatids separate in
meiosis II
18
• What is the difference between prophase I
and prophase II?
• Tetrads form and crossing over occurs in
prophase I and not prophase II
19
• How many cell are made in mitosis?
• 2
20
• How many cells are made in meiosis?
• 4
21
• What is the purpose of meiosis?
• To make cells for sexual reproduction
22
• What is the purpose of mitosis?
• To make cells for growth and repair
23
• What kind of cells are made in mitosis?
• Diploid body cells
24
• What kind of cells are made in meiosis?
• Haploid sex cells
25
• How many times is the DNA replicated in
meiosis?
• 1
26
• How many divisions are there in meiosis?
• 2
27
• How many divisions are there in mitosis?
• 1
37
• Is Meiosis I or Meiosis II more similar to the
process of mitosis?
• Meiosis II because it separates sister
chromatids just as mitosis does
