Meiosis

• Meiosis


  A type of cell division that produces haploid gametes, reducing chromosome number by half.
• Diploid


  A cell containing two complete sets of chromosomes, one from each parent (2n).
• Haploid


  A cell containing one complete set of chromosomes (n).
• Gametes


  Reproductive cells (sperm and egg) that carry half the genetic information.
• Crossing Over


  The exchange of genetic material between homologous chromosomes during Prophase I of meiosis.
• Independent Assortment


  The random distribution of maternal and paternal chromosomes into gametes during meiosis.
• Prophase I


  The first stage of meiosis I where homologous chromosomes pair and crossing over occurs.
• Metaphase I


  The stage of meiosis I where homologous chromosome pairs align at the cell's equator.
• Anaphase I


  The stage of meiosis I where homologous chromosomes are pulled to opposite poles.
• Telophase I


  The final stage of meiosis I where nuclear membranes form around the separated chromosomes.
• Prophase II


  The first stage of meiosis II where chromosomes condense again.
• Metaphase II


  The stage of meiosis II where chromosomes align at the cell's equator.
• Anaphase II


  The stage of meiosis II where sister chromatids separate and move to opposite poles.
• Telophase II


  The final stage of meiosis II where nuclear membranes form around the new sets of chromosomes.
• Genetic Variation


  Diversity in gene frequencies, crucial for evolution and adaptation.
• Natural Selection


  The process where organisms better adapted to their environment tend to survive and reproduce.
