Which of the following occurs during meiosis? Haploid nuclei with unpaired chromosomes are produced from diploid parent nuclei with paired chromosomes.
Which of the following occur during meiosis?
During meiosis one cell? divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid. Meiosis produces our sex cells or gametes? (eggs in females and sperm in males).
What happens during meiosis quizlet?
A process in cell division during which the number of chromosomes decreases to half the original number. It occurs by two divisions of the nucleus and results in the production of 4 sex cells (gametes).
Which of the following occurs during meiosis but not during mitosis?
Which of the following occurs during meiosis but not during mitosis? Synapsis occurs. The pairing of homologous chromosomes that only occurs during prophase I of meiosis is called synapsis. … It has half the amount of DNA as the cell that began meiosis.
Which of the following occurs during meiosis but not during?
(d) Synapsis occurs during meiosis but not during mitosis during mitosis.
What events occur during meiosis I and meiosis II?
Homologous pairs of cells are present in meiosis I and separate into chromosomes before meiosis II. In meiosis II, these chromosomes are further separated into sister chromatids. Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.
Which of the following occurs during mitosis?
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. … Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.
What is meiosis and mitosis quizlet?
Mitosis is the process of dividing body cells for growth and repair. Daughter cells are identical to the parent cell. (diploid cells) Meiosis is the process of producing gametes (sperm and eggs). ( haploid cells)
What is the overall result of meiosis?
By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. 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.
What is the definition of meiosis quizlet?
define meiosis. Meiosis is the division of gametes (sex cells) by reducing the number of 2n cells to half to make 1n cells.
Which of the following occurs during both meiosis and mitosis?
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.
Which of the following occurs during interphase?
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
Which of the following occurs during metaphase?
Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell. … As metaphase continues, the cells partition into the two daughter cells.
Which of the following does not happen during mitosis?
Explanation : Replication of DNA does not occur in mitosis. Replication of DNA occurs during S phase, an entirely different phase of cell division.
