Meiosis and mitosis are both types of cell division that occur in living organisms. However, they differ in several key ways.

Meiosis is a type of cell division that occurs specifically in sexually reproducing organisms and results in the production of gametes, such as eggs and sperm. It involves two rounds of division, resulting in the production of four daughter cells that are genetically distinct from each other and from the parent cell.

During the first round of meiosis, the replicated chromosomes are separated and distributed into the daughter cells. This results in cells that have half the number of chromosomes as the parent cell. In the second round of meiosis, the remaining replicated chromosomes are separated and distributed into the daughter cells, resulting in cells with the same number of chromosomes as the parent cell, but with a unique combination of genetic material.

Mitosis, on the other hand, is a type of cell division that occurs in all types of organisms and is responsible for the production of new cells for growth, repair, and replacement. It involves a single round of division and results in the production of two daughter cells that are genetically identical to each other and to the parent cell.

During mitosis, the replicated chromosomes are aligned in the center of the cell and then separated and distributed into the daughter cells. This results in cells with the same number of chromosomes as the parent cell and with the same genetic material.

One key difference between meiosis and mitosis is the number of daughter cells produced. Meiosis results in the production of four daughter cells, while mitosis results in the production of two daughter cells. Another key difference is the genetic makeup of the daughter cells. In meiosis, the daughter cells are genetically distinct from each other and from the parent cell, while in mitosis, the daughter cells are genetically identical to each other and to the parent cell.

Overall, meiosis and mitosis are both important processes that play crucial roles in the life cycles of living organisms. Understanding the differences between these two types of cell division can help us better understand how cells and organisms function and evolve.

Meiosis is the process of cell division in which the numbers of chromosomes are produced by half through separation of homologous chromosomes, producing two haploid cells. A Crossing over during meiosis. If the genes are not regulated properly, it might cause serious health issues in humans, such as cancer. The result of this process is the formation of egg and sperm cells, with chromosome counts from 46 to 23. Meiosis is a two-step procedure, reducing the chromosome number by half. It is useful not only to generate new cells but also to help in growth and development.

B The end product of mitosis is two n daughter cells with unduplicated chromosomes whereas the end product of meiosis is four n cells with unduplicated chromosomes. In meiosis, the two homologous chromosomes form bivalents or tetrads. Make a drawing of each stage using the space provided to the right of its description. E Crossing-over occurs during Anaphase ofMitosis. You will also have to recreate the crossing over and recombination that occurs during meiosis using the chromosomes models provided for you. Meiosis is the process responsible for ensuring genetic diversity between individuals of the same species.

Mitosis and meiosis share some similarities, but the processes have distinct differences as well. Class 9 and Class 11 NCERTs cover differences between Mitosis and Meiosis. The independent assortment of chromosomes during metaphase I also leads to genetic diversity. Similarities between mitosis and meiosis Although these are different processes, both mitosis and meiosis share a number of similarities. The spindles from opposite sides of the cell are attached to different homologous chromosomes. Cell reproduction is the process of creating new species using a single-parent cell.

C The nuclear envelope breaks down. The only human cells that are made by meiosis are gametes, or sex cells: the egg or ovum for females and the sperm for males. Anaphase: Physical Splitting Occurs Anaphase is the stage in which the physical splitting occurs. You will also study the fungus known as Sordaria fimicola for physical evidence of crossing over. C Genes located far apart on the chromosome cannot be linked. But before you read the differences you should know- What is mitosis? The spindle will break down, but the nuclear envelope may not reappear and the chromosomes may stay tightly wound.

In both books, the topic is explained with well-illustrated and properly labeled diagrams. Make sure to collect the data and estimate the percentage of crossing over that occurs between the centromere and the gene locus for a tan spore color in the fungus Sordaria Fimicola. The region of elongation is the area in which growth in length occurs. This table will also come in handy while revising the topic. D The haploid number of chromosomes is changed to the diploid number. At Prophase, Mitotic spindle forms after the development of 2 identical sister chromatids.

This third cell division is not present in mitosis, so it should help you to tell the difference between mitosis and meiosis. A Meiosis produces 4 haploid cells while mitosis produces 2 diploid cells B Meiosis produces 4 diploid cells while mitosis produces 2haploid cells. Exchange of Segments The two chromatids of a chromosome do not exchange segments during prophase. In other words, the genetic constitution of daughter cells differs from that of the parent cell. Mitosis is how we get new skin cells, bone cells, blood cells, and other cells. Separation of chromosomes The chromosome separates simultaneously during anaphase.

C Meiosis maintains the ploidy level,while mitosis reduces it D Prophase I of mitosis results in the formation of a tetrad but not in prophase I of mitosis E Mitosis and not meiosis occurs in the gametes. Chances are likely in meiosis to exhibit genetic variations from DNA shuffling. Class 12 covers the topic in much more detail whereas Class 9 only introduces the topic. Two chromatids of chromosome are genetically different due to crossing over. Also Read: What are the Similarities Between Mitosis and Meiosis? This process is a part of meiosis, but not a part of mitosis, so it should help you to distinguish the 2 processes.

In meiosis, the cell divides more than it does in mitosis. In this article we will talk about what are the differences between mitosis and meiosis. Similarities Between Mitosis and Meiosis Apart from its cell division or reproductive processes, there are 3-4 similarities between meiosis and mitosis. Pairing of Chromosome Pairing of chromosomes does not occur in mitosis. The root cap functions in protection.

She is a grant reviewer for the National Institutes of Health and the National Center for Complementary and Alternative Medicine. It is random how homologous chromosome pairs line up during that stage, so the mixing and matching of traits have many choices and contribute to the diversity. Movement of Chromosomes during Anaphase Similar chromosomes move towards the opposite poles in anaphase. B Both synapsis and crossing-over occurs. Which of the following statements regarding meiosis and mitosis is correct? In other words, the genetic constitution of the daughter cells is identical to that of the parent cells. You may get information about many such topics of Biology on Vedantu's website for free. Also Read: What Is Meiosis? Each chromosome has similar genes; one parent may provide a gene for brown hair and the other parent may provide the gene for blond hair.

These 4 new cells rely on different genetic information, because during the meiosis procedure, genetic material was exchanged. Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as parent nucleus, typical of ordinary tissue growth. Synapsis describes the process that 2 chromosomal pairs use to share and exchange DNA. Mitosis is a critical process to life, and hence this is controlled by several genes. It is very important for a student to know both of these as they are part of many other topics in zoology as well as botany. Metaphase: Chromosomes Line Up at Cell's Equator In metaphase, the chromosomes line up at the equator, or middle, of the cell, and the newly formed spindle attaches to those chromosomes to prepare for pulling them apart. Chromosomes are double stranded in anaphase I, but single stranded in anaphase II.
