Mitosis

Meiosis

Each chromosome replicates. The result is two genetically identical sister chromatids Chromosomes not yet visible but DNA has been duplicated or replicated
Prophase I – crossing-over recombination – Homologous chromosomes (each consists of two sister chromatids) appear together as pairs. Tetrad is the structure that is formed. Segments of chromosomes are exchanged between non-sister chromatids at crossover points known as chiasmata (crossing-over) Prophase –Each of the duplicated chromosomes appears as two identical or equal sister chromatids, The mitotic spindle begins to form. Chromosomes condense and thicken
Metaphase I Chromosomes adjust on the metaphase plate. Chromosomes are still intact and arranged as pairs of homologues Metaphase -The chromosomes assemble at the equator at the metaphase plate
Anaphase I Sister chromatids stay intact. However, homologous chromosomes drift to the opposite or reverse poles Anaphase – The spindle fibres begin to contract. This starts to pull the sister chromatids apart. At the end of anaphase, a complete set of daughter chromosomes is found each pole

Eukaryotic cells Diploid cells
