Edpuzzle Meiosis Answers Key

Here is the Edpuzzle answers key to the topic Meiosis:

  • Question: How many cells are produced by meiosis?
    Answer: 4
  • Question: What is happening during Prophase I?
    Answer: Homologous chromosomes pair up and crossing over occurs.
  • Question: What is recombination and why is it important?
    Answer: Some of the genetic material is swapped between the two chromatids, now the chromosomes are a mixture of the DNA from the two parents. This is important as it leads to genetic diversity.
  • Question: What has formed at the end of meiosis I?
    Answer: 2 daughter cells
  • Question: True or False – The DNA replicates again right before meiosis II.
    Answer: False
  • Question: Describe the cells which are formed at the end of the process of meiosis
    Answer: 4 cells, which are genetically different, and each hold half the amount of DNA of the original cell
  • Question: How many Chromosomes do humans have?
    Answer: 46
  • Question: When a cell contains two sets of chromosomes, one from the mother and one from the father, it is called
    Answer: diploid
  • Question: When a cell contains only one of each chromosome, there are no partners, this is called
    Answer: haploid
  • Question: What is the haploid number for humans?
    Answer: 23
  • Question: What type of cells does mitosis make?
    Answer: body cells like skin and stomach cells
  • Question: In which phase do your cells replicate your chromosomes?
    Answer: interphase
  • Question: When 46 chromosomes replicate, how many chromatids are there?
    Answer: 92
  • Question: Mitosis produces _______ cells while meiosis produces _______ cells.
    Answer: 2 diploid; 4 haploid
  • Question: What are homologous chromosomes?
    Answer: Chromosomes that are similar in size to each other and have similar traits at the same location on each chromosome. One comes from mom, other from dad.
  • Question: During which phase of Meiosis does crossing-over occur?
    Answer: prophase 1
  • Question: What does crossing over of homologous pairs or homologous chromosomes do to siblings with the same parents?
    Ans: Causes genetic variation in which siblings look different from each other
  • Question: How are the chromosomes arranged differently in Metaphase I (meiosis) compared to Metaphase during mitosis?
    Answer: In Metaphase I, homologous chromosomes are paired up in the center of the cell
  • Question: After Meiosis I, the end result is
    Answer: Two cells that each have half the number of chromosomes they started with
  • Question: Prophase II is not as eventful as Prophase I because
    Answer: crossing over does not occur
  • Question: Look at the chart and the cells. You started with one cell with 46 chromosomes. What is the product of meiosis?
    Answer: 4 cells with 23 chromosomes
  • Question: Which events during meiosis increase genetic variation by ensuring that each egg and each sperm will be unique? Mark 2.
    Answer: crossing over & independent assortment
  • Question: What is the term for incorrect separation of chromosomes?
    Answer: nondisjunction
  • Question: When can you see chromosomes?
    Answer: only when they are in their condensed form
  • Question: If you have a cell with 46 chromosomes and it replicates its chromosomes before cell division, how many chromosomes do you now have in the cell?
    Answer: 46
  • Question: In anaphase sister chromatids get pulled apart. How many chromosomes are now present in the cell?
    Answer: 92

    Answer: DNA replication will occur
  • Question: How many cell divisions occur with Meiosis?
    Answer: 2 (Meiosis I and Meiosis II)
  • Question: What happens to the chromatin in Prophase I?
    Answer: Chromatin condenses into discrete chromosomes
  • Question: What will happen to the centrosomes in Prophase I?
    Answer: The pair will go to the opposite poles of the cell
  • Question: What is another word for a homologous chromosome?
    Answer: homolog
  • Question: During Prophase I, what happens when crossing over occurs at the chiasmata between homologs or homologous chromosomes?
    Answer: The crossing over leads to genetic variation due to exchanging genetic material between the homologous chromosomes
  • Question: What happens during Anaphase I?
    Answer: The homologous chromosomes separate
  • Question: What happens during Telophase I?
    Answer: The DNA decondense, the nuclear membrane reforms, and the cytoplasm divide. Homologous chromosomes separate from each other and go to opposite ends of the cell.
