A comparison of the similarities and differences between mitosis and meiosis

Crossing over of chromosomes also happens, in which genes are transferred from one homologous chromosome to the other. Prophase is comparatively longer and may take days. Nucleoli appear again in telophase. A synaptionemal complex is absent.

Nucleoli do not reappear at telophase I. The diploid parent cell divides into four haploid cells via two major divisions called meiosis I and meiosis II.

Similarities of Mitosis and Meiosis

It is known as bouquet stage. DNA duplication occurs in each cycle. There are two cell divisions but the chromosomes divide only once. Crossing over results in genetic material mixing between homologous chromosomes.

You Might Also Like: The genetic constitution of the daughter cells differs from that of the parent cell. When an identical set of DNA is arranged in a cell, it is ready to undergo the process of mitosis. It is the first phase when crossing over and combination of genes takes place.

Mitosis takes place throughout the human body; it is the normal process of cell replication, used for growth and repair.

It helps in multiplication of cells. Anaphase II The spindle fibers connected to each sister chromatid shorten, pulling one sister chromatid to each pole. The DNA replicates once for two cell divisions No: Meiosis give rise to the non-identical sex cells, having two consecutive nuclear divisions, first meiotic division or meiosis I and second meiotic division meiosis II.

These are the process of the meiosis I and then in these two newly formed cells undergoes the process of meiosis II. The two chromatids of a chromosome do not exchange segments during prophase. Take part in healing and repair. In this process, the produced cells are called spores or gametes.

Comparing mitosis and meiosis

Number of daughter cells: Meiosis occurs in two distinct phases: On the contrary, the daughter cells produced in meiosis have diverse genetic combinations. The number of chromosomes remains same by the end of the mitosis process. Telophase — Here the chromosomes again decondensed, the spindle fibers and the nuclear membrane start forming again around nucleoli.

Most importantly, somatic cells divide by mitosis, and germ cells divide by meiosis. Moreover, each cell division has four subphases: Mother cell can be diploid or haploid.

Division of the centromeres take place during anaphase. This occurs in meiosis I in a long and complicated prophase I, split into five sub-phases. Mother cell is always diploid. There are two nuclear divisions. The separated sister chromatid is called as a daughter chromosome and becomes a full chromosome.Dec 13,  · Similarities: Both Mitosis and Meiosis are types of cell division in which one cell gives rise to more than one cell.

Both follow duplication of chromosomes. Differences in Purpose. Though both types of cell division are found in many animals, plants, and fungi, mitosis is more common than meiosis and has a wider variety of functions.

What Is The Difference Between Mitosis And Meiosis?

Mitosis occurs in many different tissues of animals, but meiosis only happens in specialized tissues. During mitosis, the changes in the chromosomes are asexual.

Meiosis. Dec 12,  · This feature is not available right now. Please try again later. Basis for Comparison Mitosis Meiosis; Meaning: Key Differences Between Mitosis and Meiosis. Similarities. Mitosis and Meiosis both occur in the nucleus of the cell and are observable under the light microscope.

Both the process involves the division of the cell. Differences in Purpose. Though both types of cell division are found in many animals, plants, and fungi, mitosis is more common than meiosis and has a wider variety of functions.
