Question

which of the following are true of meiosis? (select all that apply) * it produces 2 identical cells there are 23 chromosomes in each new cell at the end of the process it occurs with egg and sperm cells pmat occurs twice the main purpose of this process is for growth and repair of cells it provides genetic diversity

Explanation:

• Meiosis produces 4 non - identical cells, not 2 identical ones. So the first option is false.
• Meiosis results in haploid cells with 23 chromosomes in humans at the end of the process, so the second option is true.
• Meiosis occurs in germ - cells (egg and sperm cells), so the third option is true.
• PMAT (Prophase, Metaphase, Anaphase, Telophase) occurs twice in meiosis (meiosis I and meiosis II), so the fourth option is true.
• The main purpose of mitosis is growth and repair of cells, while meiosis is for sexual reproduction and genetic diversity, so the fifth option is false.
• Meiosis involves crossing - over and independent assortment, providing genetic diversity, so the sixth option is true.

Answer:

B. there are 23 chromosomes in each new cell at the end of the process
C. it occurs with egg and sperm cells
D. PMAT occurs twice
F. it provides genetic diversity
