Meiosis

After undergoing one round of DNA replication, the cell appears to  be dividing without further replicating its DNA. Which process is the cell most likely undergoing?

• mitosis
• meiosis
• mutation
• multiplication

When segregation occurs during anaphase I of meiosis, homologous chromosomes__________

• combine
• separate
• cross over
• mutate

When homologous chromosomes are paired during prophase I

• nuclei form around the chromosome pairs, and the cell divides into two daughter cells
• the centromeres of sister chromatids separate.
• genetic material is exchanged through breakage and reunion of portions of the chromosomes
• the paired chromosomes line up on the equatorial plate of the cell.

Meiosis results in the formation of ______, each of which has ______ found in the original cell

• four haploid cells, the same number of chromosomes
• four haploid cells, half the number of chromosomes
• two haploid cells, half the number of chromosomes
• two haploid cells, double the number of chromosomes

Which of the following increases genetic variation among the products of meiosis by reshuffling genetic information among the homologous chromosome pairs during prophase 1?

• translocation
• crossing over
• synapsis
• independent assortment

During meiosis, two sets of chromosomes in a cell are divided among the nuclei of four cells resulting from the process.  Each nuclei has

• twice the number of chromosomes as the original cell
• the same number of chromosomes as the original cell
• half the number of chromosomes as the original cell
• one-fourth the number of chromosomes as the original cell.

A meerkat has 36 total chromosomes in each body cell.  After meerkat cells undergo the process of meiosis, each gamete will have

• 16 chromosomes
• 18 chromosomes
• 36 chromosomes
• 72 chromosomes

you are observing a mammal's cell under a microscope. The cell appears to be dividing, without having first replicated its DNA.  Which process is the cell most likely undergoing?

• mitosis
• meiosis
• mutation
• multiplication

Unlike mitosis, meiosis results in the formation of ______

• two genetically different diploid cell
• four genetically differed haploid cells
• four genetically identical diploid cells
• four genetically identical haploid cells

Through the process of meiosis, sex cells containing one of each chromosome type are created.  These sex cells are also known as____

• alleles
• genes
• gametes
• chromatids
