1. MEIOSIS

Click here to watch a video clip on meiosis.
Questions:
1. How are the daughter cells compared to the parent cell after meiosis?
2. How many daughter cells are produced in meiosis?
3. What happens during prophase 1 between homologous chromosomes?
4. What are homologous chromosomes?

  1. So the different orientation of homologues in metaphase determine the parental chromosomes?

    Also, what determines how the shape of a sperm and the shape of an egg are different?

  2. And where should we answer the questions you put up?

  6. 1. After meisosis, the daughter cell has half the number of chromosomes as the parent cell.

    2. Four.

    3. During Prophase I, homologous chromosomes "cross over", creating variability.

    4. Homologous chromosomes are a pair of chromosomes that code for the same trair in the same place and "cross over" during Prophase I.

  8. Waqar, Cerebrospinal fluid is a fluid that bathes the central nervous system (brain and spinal cord). It acts as a cushion, protecting the brain and spine from injury.

  9. -after meiosis he daughter cells have only half the amount of chromosomes
    -there are 4 daughter cells after meiosis
    -crossing over occurs during prophase1
    -homologous chromosomes are the chromosomes in each cell that code for the same thing
