Meiosis is a complex and essential process that occurs in sexually reproducing organisms. It is the process of cell division that produces gametes, or reproductive cells, with half the number of chromosomes as the original cell. The phrase that best describes this process is "reducing the chromosome number by half."

Meiosis is divided into two main stages: meiosis I and meiosis II. During meiosis I, the cell undergoes a series of events known as prophase, metaphase, anaphase, and telophase. During prophase, the chromosomes begin to condense and become visible under a microscope. In metaphase, the chromosomes line up along the center of the cell. In anaphase, the chromosomes are pulled towards opposite poles of the cell. Finally, in telophase, two daughter cells are formed, each with a full set of chromosomes.

Meiosis II is similar to meiosis I, with prophase, metaphase, anaphase, and telophase occurring again. However, in meiosis II, the daughter cells produced in meiosis I undergo further division to produce four gametes, each with half the number of chromosomes as the original cell.

The phrase "reducing the chromosome number by half" accurately describes the process of meiosis because it is the main function of this process. Meiosis reduces the chromosome number from the diploid number (2n) to the haploid number (n), which is necessary for sexual reproduction to occur. Without meiosis, offspring would have twice the number of chromosomes as their parents, which would lead to genetic abnormalities and developmental issues.

In conclusion, the phrase "reducing the chromosome number by half" accurately describes the process of meiosis because it is the main function of this essential process. Meiosis is essential for the production of gametes, which are necessary for sexual reproduction to occur. Without meiosis, offspring would have twice the number of chromosomes as their parents, leading to genetic abnormalities and developmental issues.

She places 2 cells in a dish and records the number of cells over time. Pairs of homologous chromosomes exchange segments is the phrase that best describes the process of crossing over.

Produces haploid gametes ; A kidney cell is an example of which type of cell. What describes the function of meiosis? In facilitated diffusion, the cell transports materials using proteins which acts a binders. This process is required to produce egg and sperm cells for sexual reproduction. Substance A Substance B They will be equal. Before meiosis begins, during S phase of the cell cycle, the DNA of each chromosome is replicated so that it consists of two identical sister chromatids, which remain held together through sister chromatid cohesion.

which phrase best describes the process of meiosis

These daughter cells are all genetically identical. The mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes. In humans, meiosis is the process by which sperm cells and egg cells are produced. The main function of the meiotic division is the production of gametes egg cells or sperm cells or spores. Therefore, we can conclude that pairs of homologous chromosomes exchange segments of their DNA is the phrase that best describes the process of crossing over. What happens during meiosis I and meiosis II? What is the main purpose of mitosis and meiosis? First, answer Part A.

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. That is option 4. In the human body, the meiosis process takes place to decrease the number of chromosomes in a normal cell which is 46 chromosomes to 23 chromosomes in eggs and sperms. At fertilization, what happens to the sex cells? Which phrase best describes the process of meiosis? Meiosis Test Flashcards Chegg. At the end of the meiotic process, four daughter cells are produced.

Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes sperm and eggs. It is this step in meiosis that generates genetic diversity. However, Meiosis I begins with one diploid parent cell and ends with two haploid daughter cells, halving the number of chromosomes in each cell. Which best describes meiosis produces cells that are identical to the original cell? Thus, the statement that best describes the process of meiosis is "it is carried out in cells that are involved in sexual reproduction". Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. Meiosis produces our sex cells or gametes? Why are there two stages of meiosis? Which phrase best describes what occurs during meiosis I? How do you describe meiosis? The diagram of meiosis is beneficial for class 10 and 12 and is frequently asked in the examinations.

The table shows her results. Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. Happens only in haploid cells D. What happens during meiosis I? In preparation for meiosis, a germ cell goes through interphase, during which the entire cell including the genetic material contained in the nucleus undergoes replication. Meiosis is the production of four genetically diverse haploid daughter cells from one diploid parent cell. The cells produced are known as the sex cells or gametes sperms and egg.

At fertilization what happens to the sex cells? Diploid cells within the testes undergo meiosis to produce haploid sperm cells with 23 chromosomes. In the male, meiosis takes place after puberty. There are two stages of meiosis: meiosis I and meiosis II. In meiosis, however, the cell has a more complex task.

Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. The correct answer is D. The process by which other chemicals combine with oxygen. A single diploid cell yields four haploid sperm cells through meiosis. What are the 10 stages of meiosis? At fertilization, what happens to the sex cells? Meiosis is part of the sexual process because gametes sperm, eggs have one half the chromosomes as diploid 2N individuals. Integral proteins are used to transport ions and molecules in this diffusion process and does not require energy from the cell. The process of crossing over is the exchange of genetic material specifically of a DNA segment that happens between two pairing chromosomes, that is, they exchange sections of their DNA.

Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Since the four daughter cells only have half the number of chromosomes of the parent cell, they are considered haploid. The key difference between nondisjunction in meiosis 1 and 2 is that during meiosis 1, homologous chromosomes fail to separate while in meiosis II sister chromatids fail to separate. If the same amount of en … ergy is put into a 100-gram block of each substance, and if both blocks were initially at the same temperature, which one will now have the higher temperature? The result is a hybrid chromosome with a unique pattern of genetic material. DNA replication precedes the start of meiosis I.
