During prophase I, differences from mitosis begin to appear. As in mitosis, the cell grows during G 1 1 phase, copies all of its chromosomes during S phase, and prepares for division during G 2 2 phase. Gamete: Now after meiosis, there are four daughter cells which if male, are four sperm cells and if female, are one egg cell and three other cells that form around the egg cell. Your task is to create an index card flip movie that shows the following basic steps of Mitosis. Meiosis I Before entering meiosis I, a cell must first go through interphase. Keeps number of chromosomes from doubling each generation and provides genetic diversity in offspring. Telophase II: In this stage the cells start dividing and the nuclear membrane reforms around the chromatids. As we have studied, mitosis is the division of the nucleus of somatic (normal body) cells with the intent of making two exact copies of the parent cell. Meiosis The process that occurs in the formation of sex cells by which the number of chromosomes is produced by half. Metaphase II: In this stage the sister chromatids line up at the center and the spindle fibres attach and start pulling on them.Īnaphase II: This is the stage where the chromatids seperate and start moving towards opposite sides of the cells.

Prophase II: In this stage the centrosomes start moving to opposite sides of each cell. Telophase 1: In this stage the nuclear membrane forms again around the chromatid, the two daughter cells forming are haploid.

Interphase
In the interphase of meosis, a sex cell begins to grow in size and prepare for growth.

Prophase 1: In this stage the chromatids connect and cross over, this is when the chromatids trade sections.
