  • Meiosis I: se intercambia material genético o recombinación de los cromosomas y se producen dos células hijas.
  • Meiosis II: las células hijas se dividen sin duplicar sus cromosomas, resultando en cuatro células hijas con la mitad de los cromosomas de la célula original
    • Primera fase de la meiosis

    • Profase I: se empiezan a construir las estructuras que van a ayudar a separar los cromosomas en la célula.
    • Prometafase I: se hilan los microtúbulos a los cromosomas.
    • Metafase I: los cromosomas se alinean en el centro de la célula.
    • Anafase I: se separan los cromosomas hacia los polos celulares.
    • Telofase I: se separan dos célula hijas.
    Segunda fase de la meiosis

    • Profase II: se forman nuevas estructuras para separar los cromosomas.
    • Prometafase II: se hilan los microtúbulos a los cromosomas.
    • Metafase II: los cromosomas se alinean en el centro ecuatorial de la célula.
    • Anafase II: las hebras de los cromosomas se separan y se arrastran a los polos.
    • Telofase II: se dividen las células originando cuatro células hijas finales.
