How many chromosomes are in each daughter cell at the start of mitosis?
The cell copies its chromosomes, but then separates the 23 pairs to ensure that each daughter cell has only one copy of each chromosome. A second division that divides each daughter cell again to produce four daughter cells. See below for more detailed descriptions of mitosis and meiosis.
What is formed at the end of meiosis II?
At the end of meiosis II, we form special sex cells called gametes. This process ensures that these gametes only contain one set of chromosomes. They get their other set of chromosomes when they are fertilized by another gamete.
What is the state of DNA at the end of meiosis I what about at the end of meiosis II?
What about at the end of meiosis II? At the end of meiosis I the DNA will be replicated. In other words, at the beginning was 1 cell with 23 pairs of chromosomes carrying the DNA and at the end will be 2 cells with 23 pairs of chromosomes carrying two chromatic of DNA in each cell.
What is the ploidy of the DNA at the end of meiosis I what about at the end of meiosis II?
The ploidy of the DNA at the end of meiosis I each of the two daughters are haploid. At the end of meiosis II, each of the 4 daughters are also haploid.
What are the 4 phases of meiosis 2?
Sister chromatids separate during a second round, called meiosis II. Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
At what stage in meiosis are Bivalents formed?
Why are there two divisions in meiosis?
From Amy: Q1 = Cells undergoing mitosis just divide once because they are forming two new genetically identical cells where as in meiosis cells require two sets of divisions because they need to make the cell a haploid cell which only has half of the total number of chromosomes.
