Difference Between Meiosis 1 and Meiosis 2

Meiosis 1 vs Meiosis 2

Cell division is a vital process in reproduction. Without it we will not exist simply because we all came from a single cell. Cell division starts with mitosis as discussed in another article (Difference between Mitosis and Meiosis 2).

Cell division can be clearly seen in microscopic organisms such as an amoeba. By using a microscope, cell division can be seen clearly. When it is time to replicate, cells divide equally. Simple plants and animals undergo this type of process.

For complicated organisms such as humans, mitosis takes place. In this process, the genes which contain the information will then be divided and shared equally between the new daughter cells. That is mitosis to give you a bird’s eye view.

In meiosis, a similar process also occurs when humans produce sex cells such as sperm and eggs. However, in this case, chromosomes don’t replicate until fertilization occurs.

Meiosis 1 and meiosis 2 are two separate substages of meiosis. Meiosis 1 occurs by producing genetic recombination in the daughter cells while in meiosis 2 each of the four daughter cells will contain half the amount of chromosomes of the parent cell.

Meiosis 1 has five phases including: prophase 1, metaphase 1, anaphase 1, telophase 1 and interphase. In meiosis 2, it varies. In some organisms, telophase 1, interphase, and prophase 2 does not occur. In plants and animals, meiosis 2 consists of four stages of cell division.

Meiosis is generally the process in which sex cells whether male or female are formed. It produces cells with half the number of chromosome so that during reproduction the produced cells will have the normal amount of chromosomes. Animal and plant cells divide with the same process.

Summary:

1.Meiosis 1 has five phases: prophase 1, metaphase 1, anaphase 1, telophase 1 and interphase while meiosis 2 has varying stages depending on the organism.

2.Meiosis 1 recombines genes on the daughter cells produced while in meiosis 2 chromosomes are divided into these daughter cells.

3.Both substages of meiosis occur from days to weeks.
