What term is used to mean, "chromosome pairs" with DNA segments, or genes, for the same traits?
analogous
parallel
homologous
homozygous
2
Which description best identifies characteristics of asexual reproduction?
one parent, no gamete union, offspring identical to parent
two parents, no gamete union, offspring identical to parent
one parent, gamete union, offspring similar to the parent
two parents, gamete union, offspring similar to parents
3
Mitosis, a stage in the cell cycle, is important for what reason?
reduction of the cell’s chromosome number
removal of diseased cells
division of the cytoplasm
growth and repair of an organism
4
In which stage of meiosis does number of chromosomes decrease from diploid (2n) to haploid (n)?
anaphase I
prophase I
anaphase II
prophase II
5
What are the structures labeled A in the drawing?
spindle fibers
chromatids
centromeres
centrioles
6
Which statement describes the number of chromosomes in a newly formed cell after mitosis?
They are equal to the number of the parent cell.
They are double the number of the parent cell.
They are half the number of the parent cell.
They are double the number of two parent cells.
7
Which description best fits the activity of a cell during interphase?
The cell differentiates to have a new function.
The cell splits in two, w/ 1/2 normal number of chromosomes.
The cell carries on metabolism and normal functions.
The cell splits in two.
8
Analysis of a sample human cells' nuclei have 23 chromosomes. What types of cells are these?
ova
liver cells
white blood cells
skin cells
9
Carcinogens can cause failures in cell regulation signals of cycling. What might occur?
uncontrolled cell growth in the form of cancer
normal mitosis
cell plates form
apoptosis
10
During which phase of mitosis are sister chromatids pulled away to opposite ends of the cell?
prophase
anaphase
telophase
metaphase
11
Telophase is followed by division of cytoplasm, of daughter cells. What is this process called?
prophase
cytokinesis
synthesis phase
interphase
12
In which phase of meiosis do homologous chromosomes align as tetrads in the middle of the cell?
metaphase I
prophase I
metaphase II
prophase II
13

G1 stage
S stage
G2 stage
M stage
15
The timing and rate at which a cell divides is coordinated by which complexes?
protein synthesis
nuclear division
cyclin/CDK combinations
DNA replication
16
What stage of mitosis is shown in the drawing?
telophase
metaphase
prophase
anaphase
17
Describe the actions of the cell’s chromosomes during metaphase, a stage of mitosis.
They move toward the poles of the cell.
They line up in the middle of the cell.
They condense to become chromatin.
They duplicated.
18
What process is taking place in the illustration shown below?
prophase II
crossing over
fertilization
polyploidy
19
In what organism type does cell division end w/a plate between daughter nuclei in cytokinesis?
protist
bacterium
animal
plant
20
What is the significance of meiosis in helping to maintain continuation of a species?
Equal numbers of eggs and sperm are produced by meiosis.
Meiosis produces eggs and sperm that are alike.
Meiosis produces genetic variation in the gametes.
Meiosis passes traits thru gametes in asexual reproduction.
