Meiosis

• Meiosis: a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores
• During meiosis, homologous chromosomes is when the paternal(father) cell and the maternal(mother) cell pair up inside a cell
• Crossing over is the process where homologous chromosomes pair up and exchange genetic material to form new chromosomes
• Haploid is half the set of chromosomes
• Diploid is two sets of chromosomes
• Diploid is double the set of chromosomes
• Gametes are sex cells.(Sperm and eggs)
• A zygote is the fusion of the sperm and ova at fertilization
• Meiosis is the cell division that produces gametes.
• Prophase 1 is when the chromosome condenses and the nuclear envelope breaks down
• Metaphase 1 is when the pair of homologous chromosomes move to the equator of the cell
• Anaphase 1 is when the homologous chromosomes move to opposite poles of the cell
• Telophase 1 and cytokinesis is when the chromosomes gather at the poles of the cell and the cytoplasm divides creating 2 identical cells
• Prophase 2 is when a new spindle forms around the chromosomes of each cell
• Metaphase 2 is when the chromosomes line up at the equator of each cell
• Anaphase 2 is when the centromere divides in both cells. Which results in the chromatids to move to opposite poles of the cell.
• Telophase 2 and cytokinesis is the process of the nuclear envelope forming around each set of chromosomes. Which allows the cytoplasm to divide.
• Meiosis takes place to produce 4 non-identical daughter cells(Sperm and egg cells)
