Mitosis vs Meiosis

What is the best explanation for why chromosomes line up in the center of the cell before starting to split apart?

• to complete crossing over

• to match up with their homologous pair

• to make sure each daughter cell gets the correct amount of DNA

• to detach from their centromeres

What happens during Meiosis I?

• Cells undergo apoptosis

• Homologous chromosomes separate into two different cells

• Chromatids of replicated chromosomes segregate into daughter cells

• DNA replicates

What happens before meiosis occurs (pre-meiosis)?

• Chromosomes separate

• Gametes split apart

• DNA replicates

• Cells divide

Which of these events occurs during Meiosis II?

• Replicated chromosomes are separated into sister chromatids and segregated into daughter cells

• Homologous chromosomes separate into two cells

• DNA replicates

• Cells undergo apoptosis

What is the difference between the parent cell (pre-meiosis) and one of the four daughter cells?

• The daughter cells have half as much genetic information as the parent cell; one copy of each chromosome instead of a pair of each chromosome

• The daughter cells have the exact same amount of genetic information as the parent cell

• The daughter cells have a random amount of genetic information.

• The daughter cells have twice as much genetic information as the parent cell due to DNA replication; four copies of each chromosome.

During which phase of meiosis can homologous chromosomes exchange some genetic information?

• Meiosis 1

• Meiosis 2

• Mitosis 1

• Pre-meiosis

At what stage in meiosis would you consider the cells undergoing, meiosis haploid?

• Not until Meiosis 2 is complete

• After DNA replication

• After Meiosis 1

• Never. Meiosis does not produce haploid cells.

Which process creates genetically identical cells?

• Mitosis

• Meiosis
