Production of gamets
  1. Advantages of sex in evolution
    1. Over 99.9% of eukaryotes reproduce sexually
      1. Is good for natural selection
        1. Sex can be favored when selection varies over space
          1. Sex evolves more readily when a species enviroment changes rapidly
        2. Spermatogenesis
          1. Process of espero cell development.
            1. Spermatocygogenesis
              1. Primitive cells proliferase by mitosis.
              2. Spermiogenesis
                1. Cells retain a rounded configuration Spermatids undergo a change in form during spermiogenesis.
            2. Genetic Recombination in fertilization
              1. Happens during meiosis
                1. In propase I of Meiosis I crossing over occurs when the double- stranded homologous pairs connect and exchange DNA.
              2. Meiotic events
                1. The maintenance of sexual reproduction in a highly competitive world has long been one of the major mysteries of biology given that asexual reproduction can reproduce much more quickly because 50% of offspring from sexual reproduction are males, unable to produce offspring themselves.
