A human cell ordinarily will have 23 pairs of chromosomes, for a total of 46 chromosomes. At the end of a cell cycle, including mitosis, the new cells will have
1. 23 pairs of chromosomes; 46 total
2. only the 23 maternal chromosomes
3. only the 23 paternal chromosomes
4. 92 chromosomes, as a result of doubling during the S-phase of the cell cycle
Interphase is broken into phases known as
1. G₁, S and G₂
2. S, Mitosis, and Cytokinesis
3. G₀, G₁, and G₂
4. prophase, metaphase, anaphase and telophase
Cells that will no longer undergo division enter a phase known as
1. apoptosis
2. meiosis
3. mitosis
4. interphase
5. G₀
In stage G₁, the cell
1. copies the chromosomes
2. doubles the cell contents, excluding the chromosomes
3. reduces the number of chromosomes from the diploid number to the haploid number
4. creates two identical nuclei

After a bacterial cell has undergone binary fission, how many chromosome copies will each daughter cell contain?
1. one
2. two (one maternal and one paternal)
3. forty-six
4. one pair
Which of these do mitosis and binary fission have in common?
1. They are asexual reproduction
2. Daughter cells contain paired chromosomes
3. The daughter cells have the same number of chromosomes as the parent cell
4. Both are limited to prokaryotic cells
The diploid number of chromosomes in mammals is always
1. two
2. forty-six
3. an odd number
4. an even number
A diploid cell in a buffalo has 60 chromosomes. A sperm or egg cell in a buffalo can be expected to have
1. 60 chromosomes
2. 30 chromosomes
3. 15 chromosomes
4. 120 chromosomes
"Crossing over" between maternal and paternal chromosomes takes place during
1. mitosis
2. meiosis I
3. meiosis II
4. fertilization
The process of meiosis
1. begins with diploid cells and ends with haploid cells
2. begins with diploid cells and ends with diploid cells
3. begins with haploid cells and ends with diploid cells
4. begins with haploid cells and ends with haploid cells
The first evidence of crossing-over exists in the view labeled
You can see a diploid nucleus with chromosomes that have not undergone crossing over in the field labeled
Haploid cells can be seen in the field labeled
Meiosis II takes place between fields
1. A and B
2. A and C
3. B and C
4. C and D
This human karyotype shows the sex of the individual is
1. male
2. female
Chromosomes shown here that are NOT sex chromosomes are known collectively as
1. y chromosomes
2. x chromosomes
3. karyotypes
4. autosomes
This human karyotype shows the sex of the individual is
1. male
2. female
Haploid reproductive cells are collectively referred to as
1. gametes
2. zygotes
3. blastocysts
4. polar bodies

The karyotype above is from a human cell. Its source is
1. a fertilized gamete
2. an egg cell
3. a sperm cell
4. a normal somatic (body) cell
Diploid cells that result from the fertilization of an egg cell by a sperm cell are called
1. gametes
2. zygotes
3. blastocysts
4. polar bodies
The karyotype above is from a human cell. Its source is
1. haploid
2. diploid
3. polyploid
4. a normal somatic (body) cell
The karyotype above shows paired, non-identical chromosomes that contain information for the same biological features and contain the same genes. These pairs are known as
1. sex chromosomes
2. homologous chromosomes
3. heterologous chromosomes
4. somatic chromosomes
If this karyotype were for a human sperm cell, it should
1. have only an "X" sex chromosome
2. have fewer autosomes
3. have only a "Y" chromosome
4. have more autosomes
5. have either an "X" or a "Y" chromosome
