Meiosis and mitosis are both processes of cell division, but they serve different purposes and have distinct differences. Mitosis results in two genetically identical daughter cells, while meiosis produces four genetically diverse gametes with half the chromosome number. Additionally, meiosis involves two rounds of division (meiosis I and II) and includes processes such as crossing over and independent assortment, which contribute to genetic variation. In contrast, mitosis consists of a single division and does not include these variation-generating mechanisms.

What is the correct order of the events during sperm production?
The correct order of events during sperm production is spermatogonia undergo mitosis to form primary spermatocytes, primary spermatocytes undergo meiosis I to form secondary spermatocytes, secondary spermatocytes undergo meiosis II to form spermatids, and spermatids mature into sperm cells through spermiogenesis.
How do you review stages of mitosis and meiosis and can identify the steps in drawing and descriptions?
Mitosis is the process of Repeat Division into daughter cells identical to the mother cell, Meiosis, instead has 2 stages, which the first one is called Meiosis I and its the process of Reduction Division. stage 2: In an easier format, Mitosis is not exactly, but very similar to Meiosis II, the names of the phases are the same. the only difference are the number of chromosomes inside the unique cell, and the combination of chromosomes (because to remind yourself, in Prophase of Meiosis II Crossover occurs, meaning it take a piece of the previous chromosome.
Why the chromosomes in the haploid cells that are produced by meiosis 1 look different from those produced by meiosis 2?
The chromosomes in haploid cells produced by meiosis I look different from those produced by meiosis II primarily due to genetic recombination and the reduction of chromosome number. During meiosis I, homologous chromosomes are separated and can undergo crossing over, resulting in genetic variation. In contrast, meiosis II resembles mitosis, where sister chromatids are separated, leading to the production of haploid cells that contain single chromatids. Thus, the genetic makeup of the cells differs due to the events of meiosis I.
How is prophase1 different in meiosis than in mitosis?
on prophase of mitosis the cylindrical shaped structure(centrioles) starts to move going to the both opposites sides as they move the fiber make-up structure starts to form(spindle). The spindles is the one who controls the movement of the choromosomes while it is in the process. note the chromosomes starts to become shorten ad thick that's why they r very easy to see. in prophase I of meiosis the choromoses condense and are seen to have splitinto two chromatids. One of its important features of the phrophase I of meiosis the paternal and maternal chromosomes come together in homologous pairs., well that's my answer i know its ryt... hope that i have helped you. -joan- The answer by joan simply states the processes that occur individually by mitosis and meiosis. The question is to discuss the 'Difference' instead of state the events that occur. In my understanding, prophase 1 of meiosis consists of 5 different stages - Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis. Now the question is which of these 5 stages differ from prophase of mitosis. I found that stages Leptotene (condensation of DNA) and Diakinesis (nuclear envelop fragments) are similar to that in prophase of mitosis. Thus, the difference has to lie in stages Zygotene (formation of bivalents and synaptonemal complex), Pachytene (crossing over at sites called chiasma) and Diplotene (separation of synaptonemal complex).

Are genes that are closer together more likely to separate by a crossover events in meiosis true?
Yes, genes that are closer together on a chromosome are less likely to separate by a crossover event in meiosis. This is because the chance of a crossover occurring between two genes decreases as the distance between them on the chromosome decreases. Crossovers are more likely to occur between genes that are farther apart.
What are the three major differences between the events of mitosis and meiosis?
The three major differences between the events of mitosis and meiosis are: Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse daughter cells. Mitosis involves one round of cell division, while meiosis involves two rounds of cell division. Mitosis is involved in growth, repair, and asexual reproduction, while meiosis is involved in sexual reproduction and creates gametes with half the number of chromosomes.
What events occur in telophase?
Telophase occur in both mitosis and meiosis. During telophase nuclear membrane and nuclei reforms and in meiosis it further goes for meiosis 2 which is same as mitosis
What major events occur in telophase?
Telophase occur in both mitosis and meiosis. During telophase nuclear membrane and nuclei reforms and in meiosis it further goes for meiosis 2 which is same as mitosis
What specific meiotic events contribute to meiosis leads to significant genetic variation while mitosis does not?
may be its genetical diffence
How are the process of mitosis and meiosis similar to each other?
Both processes begin with similar events, including chromosome replication.
What is the correct order of the events during sperm production?
The correct order of events during sperm production is spermatogonia undergo mitosis to form primary spermatocytes, primary spermatocytes undergo meiosis I to form secondary spermatocytes, secondary spermatocytes undergo meiosis II to form spermatids, and spermatids mature into sperm cells through spermiogenesis.
What organelles are involved in mitosis and meiosis?
There are many organelles that are directly or indirectly involved in both mitosis and meiosis.Chromosome (the main part of meiosis and mitosis; divides and splits)centrioles (provides the spindle fibers)plasma membrane (grows larger for the cell to divide)mitochondria (supplies energy)
