Prophase I. Prophase I is the longest phase of meiosis. It is very similar to prophase of mitosis, but with one very significant difference.
Q. What are the key events of the stages of meiosis?
Important events of meiosis are:

Q. In which of the meiosis stages listed below do homologous chromosomes align at the equator of the spindle?
Metaphase I | Back to Top Metaphase I is when tetrads line-up along the equator of the spindle. Spindle fibers attach to the centromere region of each homologous chromosome pair. Other metaphase events as in mitosis.

Q. Which stage of meiosis is represented in the diagram?
The stage represented in the diagram is Metaphase II of Meiosis II where the chromosomes are aligned along the equatorial plane, attached to the spindle apparatus.
Q. What step takes place in both mitosis and meiosis?
Aside from these two distinct purposes, both mitosis and meiosis occur in multiple stages during which the same general things happen: DNA replication and condensation, nuclear membrane degradation, spindle formation, chromosomal segregation and nuclear reformation.
Q. Which of the following is a key difference between mitosis and meiosis?
Mitosis involves the division of body cells, while meiosis involves the division of sex cells. The division of a cell occurs once in mitosis but twice in meiosis. Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis.
Q. What cell is mitosis?
Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
Q. What is the most important result of meiosis?
Question: An important result of meiosis is that : gametes receive one copy of each member of each pair of homologous chromosomes. gametes are formed that are diploid. each gamete receives one member of each pair of homologous chromosomes and gametes are formed that are haploid.

Q. What are the steps of meiosis 2?
In meiosis II, the phases are, again, analogous to mitosis: prophase II, metaphase II, anaphase II, and telophase II (see figure below). As shown in the figure below, meiosis II begins with two haploid (n = 2) cells and ends with four haploid (n = 2) cells.
