Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).
Full Answer
four gamete cellsMeiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
So, the correct option is 'Asexually reproducing diploid individuals'.
Which is true of daughter cells produced by meiosis II? They are haploid; they are genetically variable.
So, the correct answer is 'Meiosis produces gametes that contain one complete haploid set of chromosomes'
Meiosis is the production of four genetically diverse haploid daughter cells from one diploid parent cell. Meiosis can only occur in eukaryotic organisms....How is Meiosis I Different from Meiosis II?Meiosis IMeiosis IIStarts as diploid; ends as haploidStarts as haploid; ends as haploid17 more rows•Mar 1, 2022
The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).
The only statement that is not true about daughter cells of mitosis and meiosis is e. In meiosis, the daughter cells are genetically identical. On the contrary, the daughter cells produced by meiosis are not genetically identical. This occurs in order to increase genetic diversity.
Mitosis produces two genetically identical diploid cells, whereas meiosis produces four non-identical haploid cells.
The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
Gametes are produced by mitosis (not meiosis) and after fertilization a diploid zygote is created. The single zygote cell never grows or divides my mitosis. It can only divide by meiosis to produce haploid cells once more, which then produce the main adult body.
four haploid gametesAnswer and Explanation: Meiosis produces four haploid gametes. Gametes are sex cells, such as sperm and eggs. A haploid cell has one set of chromosomes, which is half the number of chromosomes as normal diploid body cells.
Which of the following correctly explains the difference between mitosis and meiosis? Mitosis undergoes cell division only once, while meiosis undergoes cell division twice.
o, the correct statement is 'In both mitosis and meiosis the replication of DNA and chromosomes occurs at the same stage.
Which statement correctly compares mitosis and meiosis? Mitosis results in the production of two genetically identical diploid cell and meiosis produces four different haploid cells.
Which of the following occur in both mitosis and meiosis? Explanation: The separation of sister chromatids is the only item of the answer choices that occurs in both mitosis and meiosis. Prophase II and metaphase II only occur in meiosis, as does recombination between homologous chromosomes.
Meiosis happens in the body cells of multicellular organisms.
Meiosis helps maintain the correct number of chromosomes during reproduction.
The cells that result from mitosis have half the proper number of chromosomes.
Cytokinesis is when the cytoplasm and its contents divide.
Haploid organisms like fungi produce gametes in their fruiting bodies called sporangia (singular sporangium). These propagules are called spores and they germinate to give rise to mycelia which are invariably haploid, breeding true for the genetic background of their mycelial parent. This mode of reproduction is asexual because the spores (indeed they are asexual spores) are not procured through fertilization between gametes. New mycelia can be generated through the growth of fragmented hyphae too. This is technically referred to as vegetative reproduction.
Formation of female gametes. The female gametes, or eggs, are formed in the ovules, within the flower. A certain diploid cell undergoes meiosis; however, in this case the result is four haploid megaspores—"large spores"). Three of the megaspores die, and the remaining one undergoes mitosis several times. One of these daughter cells then functions as an egg, ready to be united with a sperm.
Formation of male gametes. In the anthers of a flower, certain diploid cells undergo meiosis , forming haploid spores (called microspores—"little spores"). These microspores divide by mitosis to form two-celled pollen, consisting of a tube cell and a generative cell.
Haploid cells are usually made from diploid cells by some form of meiosis. The diploid cell in two specialized divisions turns into four haploid cells. Sometime later, a surviving haploid cell fuses with another haploid cell to form a diploid cell. The fusion is referred to as conception.
In plants, there are some intermediate steps in the process. Rather than producing egg and sperm, plants use meiosis to produce spores.
By differentiating. Since they do not need to undergo meiosis, the change from a vegetative cell to a gamete capable of fusing with another is due to a change in gene expression. For an example, see : Cell surface differentiation of Chlamydomonas during gametogenesis: I. Mating and concanavalin A agglutinability
5. The other sperm combines with the two polar nuclei, forming the triploid endosperm, a temporary food storage tissue that nourishes the developing embryo.
