Which of the following best explains the process of meiosis?

What best explains the process of meiosis?

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. During meiosis one cell? divides twice to form four daughter cells.

What is the process of meiosis?

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. … The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.

Which of the following is the best meaning for meiosis?

A simple definition of meiosis would be is this: meiosis is the process of cell division that results in the production of a haploid “daughter” cell with a haploid chromosomal number of a diploid “parent” (“original”) cell.

What stage of meiosis immediately follows meiosis 1?

Meiosis, divided into meiosis I and meiosis II, is a process in which a diploid cell divides itself into four haploid cells. Note that meiosis II immediately follows meiosis I; DNA replication does not occur after meiosis I.

Which best explains the process of meiosis 1?

one full set of chromosomes, each with 1 molecule of DNA. Which best explains the process of meiosis? The cells that result from meiosis 1 are haploid, and each chromosome consists of 2 chromatids. … One of a pair of chromosomes with similar genetic information and from different sources like the sperm and egg.

What is the main purpose of meiosis?

Therefore the purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells.

Which three processes occur during meiosis?

Three Ways that Genetic Diversity Occurs During Meiosis

  • Meiosis I and II. Meiosis occurs over two generations of cells. …
  • Crossing Over. …
  • Reduction to Haploid. …
  • Random Chromatid Assortment. …
  • Fertilization.

What is the process of meiosis and mitosis?

Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. … During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

Which of the following processes occurs during meiosis and not mitosis?

The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. 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.

Which definition represents meiosis?

meiosis, also called reduction division, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the original cell.

Which of the following best describes the difference in the results of mitosis and meiosis?

Which of the following best describes mitosis and meiosis result in daughter cells with different chromosomes? Mitosis produces two identical diploid daughter cells after one round of division. Meiosis produces four haploid daughter cells after two rounds of division.

Which of the following is the best explanation for why the diploid chromosome number of human is an even number 46 )?

Which of the following is the best explanation for why the chromosome numbers above are all even? The diploid chromosome number represents two sets of chromosomes, one from each parent, so it is always an even number.

What immediately follows meiosis?

What immediately follows meiosis I? mitosis. . One of a pair of chromosomes with similar genetic information and from different sources like the sperm and egg.

What immediately follows mitosis?

Mitosis is the process in which a eukaryotic cell (cell containing a nucleus) separates its already duplicated chromosomes (copied during the S phase) into two sets of chromosomes so there will be two identical nuclei. It is generally followed by cytokinesis which divides the cytoplasm and cell membrane.

Which of the following occurs first during meiosis?

Prophase of meiosis I is the first stage of meiosis. Pairing of homologous chromosomes occurs in early prophase. Prophase I is further sub-divided into sub-stages like leptotene, zygotene, pachytene, diplotene and diakinesis. Pairing of homologous chromosomes occur during pachytene stage.
