Meiosis Stages Quiz Questions And Answers - Quiz

The statement is false because Prophase I and Anaphase I are two different stages of meiosis. Prophase I is the first stage of meiosis I, where chromosomes condense, homologous chromosomes pair up, and crossing over occurs. Anaphase I, on the other hand, is the stage where homologous chromosomes separate and move towards opposite poles of the cell.

Prophase I is the correct answer because it is the first phase of meiosis I, which is the process of cell division that produces gametes. During prophase I, the chromosomes condense, homologous chromosomes pair up and exchange genetic material through a process called crossing over. This phase is crucial for genetic diversity as it allows for the shuffling and recombination of genetic material. Therefore, Prophase I is the correct answer in the given sequence of meiotic phases.

Anaphase II is the correct answer because it is the stage in meiosis where the sister chromatids separate and are pulled towards opposite poles of the cell. This is the final step before the formation of four haploid daughter cells. In Anaphase I, the homologous chromosomes separate, while in Anaphase II, the sister chromatids separate.

Telophase II is the correct answer because it is the final stage of meiosis II, where the chromosomes reach opposite poles of the cell and the nuclear envelope reforms around each set of chromosomes. This stage is characterized by the completion of cell division and the formation of four haploid daughter cells, each containing half the number of chromosomes as the original cell.

The distinctive characteristic of Anaphase I in meiosis is:

"Homologous chromosomes separate, with one chromosome moving to each pole of the cell."

In Anaphase I, homologous chromosomes are pulled to opposite poles by the meiotic spindle, while sister chromatids remain together. This differs from mitosis, where sister chromatids are separated.

Metaphase II is the correct answer because it is the stage in meiosis where the chromosomes align at the equatorial plate of the cell. During this phase, the homologous chromosomes have already separated in Meiosis I, and in Meiosis II, the sister chromatids align in the middle of the cell. This alignment ensures that each daughter cell receives the correct number of chromosomes during cell division.

Telophase I is the correct answer because it is the stage in meiosis where the chromosomes reach the opposite poles of the cell. During this phase, the nuclear envelope reforms around the separated chromosomes and the cytoplasm begins to divide. This marks the end of the first meiotic division and prepares the cell for the second meiotic division.

Prophase II is the correct answer because it is the first stage of meiosis II, which is the second division of meiosis. In Prophase II, the nuclear envelope breaks down, the spindle fibers form, and the chromosomes condense. This is different from Prophase I, which is the first stage of meiosis I and involves crossing over and the pairing of homologous chromosomes. Therefore, Prophase II is the correct answer in this sequence of meiotic stages.
