Solution
The stages that occur during meiosis I are:
-
Prophase I: This is the first stage of meiosis I. During this stage, the chromosomes condense and pair up. The nuclear envelope breaks down and the spindle apparatus forms.
-
Metaphase I: The paired chromosomes align at the cell's equator. This is different from mitosis where individual chromosomes line up.
-
Anaphase I: The paired chromosomes separate and are pulled to opposite ends of the cell. Unlike mitosis, the sister chromatids remain together.
-
Telophase I: The chromosomes reach the poles and the cell divides. Each daughter cell now has half the number of chromosomes but each chromosome has two sister chromatids.
-
Interkinesis: This is a period of rest that cells sometimes enter during meiosis. Not all cells go through interkinesis, but those that do, do not replicate their DNA.
Please note that these stages are specific to meiosis I. Meiosis II has its own set of stages.
