mitosis vs meiosis 1

Has two cell divisions

• Mitosis

• Meiosis

Produces diploid cells

• Mitosis

• Meiosis

Has one set of chromosomes

• Haploid

• Diploid

• Body cells

• None of the above

In humans, the haploid number of chromosomes is ____.

• 23

• 46

• 69

• 92

Which of the following is the best definition for MEIOSIS?

• the process of two haploid cells uniting

• the counting of chromosomes within a diploid cell

• a two-step process that reduces the number of chromosomes in half resulting in 4 haploid cells

• the equational division of a cell into two identical copies

In which stage of MEIOSIS does crossing over occur? (The exchange of genetic material between chromosomes in a tetrad.)

• Anaphase I

• Metaphase I

• Prophase I

• Telophase I

Which of the following are CORRECT observations about the differences between MITOSIS and MEIOSIS? (Check all that apply.)

• Mitosis produces cells that identical to the parent cell.

• Meiosis produces cells that have half the number of chromosomes as the parent cell.

• All cells go through INTERPHASE as part of the cell cycle, whether it goes to mitosis or meiosis next.

• In both types of cell division, the chromosomes are only duplicated once.

• Only in Mitosis, do you see chromosomes pair up to form a tetrad.

What phase is shown here?

• Prophase II
• Metaphase I
• Metaphase II
• Anaphase I

What phase is shown here?

• Telophase II
• Anaphase II
• Metaphase I
• Interphase I

For this question, you MUST Check all that apply:

In the process known as meiosis, what happens during interphase?

• DNA Replication

• Mitosis

• Growth

• Body Cells Are Formed
