Termini in questo insieme (12)

  • Prophase

    Chromosomes condense; nuclear envelope breaks down; spindle fibers form. No pairing of homologs

  • Prophase 1

    Prophase I: Homologous chromosomes pair up (synapsis) and perform crossing over (exchanging DNA segments).

  • Prophase 2

    Prophase II: Chromosomes re-condense in the two new haploid cells. No crossing over.

  • Metaphase

    Chromosomes align on metaphase plate in single file line

  • Metaphase 1

    Tetrads (pairs of homologous chromosomes) align side by side on metaphase plate

  • Metaphase 2

    Chromosomes align on metaphase plate in single file line

  • Anaphase

    sister chromatids are pulled apart toward opposite poles by spindle fibers

  • Anaphase 1

    homologous chromosomes are separated.

  • anaphase 2

    Sister chromatids are pulled apart

  • telophase & cytokinesis

    Nuclear envelope reforms ,cytoplasm splits, yields 2 identical diploid daughter cells (2n)

  • telophase 1 & cytokineses

    Nuclei reform, cytoplasm splits, yield 2 genetically diverse haploid cells

  • telophase 2 & cytokineses

    Nuclei reform, cytoplasm splits, yields 4 genetically diverse haploid gamete cells
