Question

match the stages of meiosis i and meiosis ii with the activity of the chromosomes at that stage.

1. homologous pairs of chromosomes come together and \synapse\. crossing over can occur resulting in exchange of genetic material between non - sister chromatids.
2. homologous pairs of chromosomes line up at the equator of the cell.
3. individual chromosomes line up at the equator of the cell.
4. homologous chromosomes are pulled to opposite poles of the cell.
5. sister chromatids are pulled apart to opposite poles of the cell.
6. two haploid daughter cells result from this phase
7. four haploid daughter cells result from this phase.
8. no replication of dna occurs during this phase between the two divisions.

Explanation:

• Prophase 1: Homologous chromosomes synapse and crossing - over occurs.
• Metaphase 1: Homologous pairs line up at the cell's equator.
• Metaphase 2: Individual chromosomes line up at the equator.
• Anaphase 1: Homologous chromosomes are pulled to opposite poles.
• Anaphase 2: Sister chromatids are pulled apart.
• Telophase 1: Two haploid daughter cells form.
• Telophase 2: Four haploid daughter cells form.
• Meiotic Interphase or Interkinesis: No DNA replication between divisions.

Answer:

1. Prophase 1
2. Metaphase 1
3. Metaphase 2
4. Anaphase 1
5. Anaphase 2
6. Telophase 1
7. Telophase 2
8. Meiotic Interphase or Interkinesis
