Which statement correctly describes the chromosomes in each daughter cell at the end of meiosis 1?

  • During meiosis one cell divides twice to form four daughter cells.
  • These four daughter cells only have half the number of chromosomes of the parent cell – they are haploid.
  • Meiosis produces our sex cells or gametes (eggs in females and sperm in males).

Meiosis can be divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II):

Meiosis I

1. Interphase:

  • The DNA in the cell is copied resulting in two identical full sets of chromosomes.
  • Outside of the nucleus are two centrosomes, each containing a pair of centrioles, these structures are critical for the process of cell division.
  • During interphase, microtubules extend from these centrosomes.

2. Prophase I:

  • The copied chromosomes condense into X-shaped structures that can be easily seen under a microscope.
  • Each chromosome is composed of two sister chromatids containing identical genetic information.
  • The chromosomes pair up so that both copies of chromosome 1 are together, both copies of chromosome 2 are together, and so on.
  • The pairs of chromosomes may then exchange bits of DNA in a process called recombination or crossing over.
  • At the end of Prophase I the membrane around the nucleus in the cell dissolves away, releasing the chromosomes.
  • The meiotic spindle, consisting of microtubules and other proteins, extends across the cell between the centrioles.

3. Metaphase I:

  • The chromosome pairs line up next to each other along the centre (equator) of the cell.
  • The centrioles are now at opposites poles of the cell with the meiotic spindles extending from them.
  • The meiotic spindle fibres attach to one chromosome of each pair.

4. Anaphase I:

  • The pair of chromosomes are then pulled apart by the meiotic spindle, which pulls one chromosome to one pole of the cell and the other chromosome to the opposite pole.
  • In meiosis I the sister chromatids stay together. This is different to what happens in mitosis and meiosis II.

5. Telophase I and cytokinesis:

  • The chromosomes complete their move to the opposite poles of the cell.
  • At each pole of the cell a full set of chromosomes gather together.
  • A membrane forms around each set of chromosomes to create two new nuclei.
  • The single cell then pinches in the middle to form two separate daughter cells each containing a full set of chromosomes within a nucleus. This process is known as cytokinesis.

Meiosis II

6. Prophase II:

  • Now there are two daughter cells, each with 23 chromosomes (23 pairs of chromatids).
  • In each of the two daughter cells the chromosomes condense again into visible X-shaped structures that can be easily seen under a microscope.
  • The membrane around the nucleus in each daughter cell dissolves away releasing the chromosomes.
  • The centrioles duplicate.
  • The meiotic spindle forms again.

7. Metaphase II:

  • In each of the two daughter cells the chromosomes (pair of sister chromatids) line up end-to-end along the equator of the cell.
  • The centrioles are now at opposites poles in each of the daughter cells.
  • Meiotic spindle fibres at each pole of the cell attach to each of the sister chromatids.

8. Anaphase II:

  • The sister chromatids are then pulled to opposite poles due to the action of the meiotic spindle.
  • The separated chromatids are now individual chromosomes.

9. Telophase II and cytokinesis:

  • The chromosomes complete their move to the opposite poles of the cell.
  • At each pole of the cell a full set of chromosomes gather together.
  • A membrane forms around each set of chromosomes to create two new cell nuclei.
  • This is the last phase of meiosis, however cell division is not complete without another round of cytokinesis.
  • Once cytokinesis is complete there are four granddaughter cells, each with half a set of chromosomes (haploid):
    • in males, these four cells are all sperm cells
    • in females, one of the cells is an egg cell while the other three are polar bodies (small cells that do not develop into eggs).

Which of the following statements correctly describes the chromosomes in each daughter cell at the end of meiosis I?

A) Each daughter cell contains 12 chromatids. Each chromatid is one of two from a single chromosome with the other one of the pair found in the other daughter cell.

B) Each daughter cell contains 12 chromosomes, each composed of two chromatids. Since the chromosomes were randomly divided, one daughter cell may contain both of a pair of homologous chromosomes, while the other cell contains both of another pair of homologous chromosomes.

C) Each daughter cell contains 12 chromosomes, each composed of two chromatids. Each chromosome is one of a pair of homologous chromosomes from the parent cell, with the other homologue found in the other daughter cell.

D) Each daughter cell contains 24 separate chromatids. Since every two chromatids were originally joined, forming one homologous chromosome, the number of chromatids is divided by two to determine the number of chromosomes.

    At the end of meiosis I, there are two haploid cells, each with two sister chromatids per chromosome. The period between meiosis I and II is termed interkinesis.

    Which of the following answer choices describes the chromosomes of the daughter cells after meiosis II?

    The daughter cells of both meiosis I and meiosis II contain only one copy of each chromosome, as homologous pairs have been separated. Both meiosis products are thus considered haploid, making this the correct answer.
