Which of the following best describes meiosis?

• It is carried out in all tissues theat require cell replacement
• It occurs only in cells in the reproductive structures of an organism
• It happens in all of the tissues except the brain and spinal cord
• It is the first stage of mitosis

Which best describes the process shown?

• mutation in which the DNA content of the gene is ltered
• segregation of sister chromatids
• condensation and segregation of the alleles
• crossing-over

How is the process used to produce sex cells different from the process used to produce body cells?

• only the process used to make sex cells uses spindle fibers
• only the process used to make sex cells produces haploid cells
• only the process used to make sex cells can result in mutations
• only the process used to make sex cells requires DNA replication

How many sperm are produced through the process of meiosis?

• Two that are identical.
• Two that are unique. 
• Four that are identical.
• Four that are unique.

A haploid cell has 

• one-half of a set of chromosomes
• one set of chromosomes
• two sets of chromosomes
• four sets of chromosomes

Crossing over is important because....

• It prevents mutations from entering the gametes. 
• It allows for even distribution of chromosomes in the gametes.
• It allows for more genetic diversity of gametes.
• It allows for genetic uniformity of gametes.
