Question

Which are true of meiosis but not mitosis? Select three options.

It generates genetically different cells.
It generates haploid cells.
It involves prophase, metaphase, anaphase, and telophase.
It involves two rounds of nuclear division.
It begins with a diploid cell.

Answer 1

Explanation:

The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.

Answer 2

It generates genetically different cells.

It generates haploid cells.

It involves two rounds of nuclear division

Explanation:

• Mitosis comprises one stage while meiosis comprise 2 stages.
• Mitosis produces/generates diploid cells ( that is, 46 chromosomes) while meiosis produces/generates haploid cells ( that is, 23 chromosomes).
• Mitosis produces/generates 2 identical daughter cells while meiosis produces/generates 4 genetically (nonidentical) different daughter cells.
• During mitosis there is only one cell division, while for meiosis there are 2 cell divisions
