Answer:
Meiosis
Meiosis is a type of cell division that results in the formation of four daughter cells each with half the number of chromosomes as the parent cell.
Mitosis
Mitosis is the type of cell division that results in the formation of two daughter cells each with the same number and kind of chromosomes as the parent cell.
Difference between Mitosis and Meiosis
Interphase
Mitosis
Each chromosome replicates. The result is two genetically identical sister chromatids
Meiosis
Chromosomes not yet visible but DNA has been duplicated or replicated
Prophase
Mitosis
Prophase –Each of the duplicated chromosomes appears as two identical or equal sister chromatids, The mitotic spindle begins to form. Chromosomes condense and thicken
Meiosis
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)
Metaphase
Mitosis
Metaphase -The chromosomes assemble at the equator at the metaphase plate
Meiosis
Metaphase I Chromosomes adjust on the metaphase plate. Chromosomes are still intact and arranged as pairs of homologues
Anaphase
Mitosis
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
Meiosis
Anaphase I Sister chromatids stay intact. However, homologous chromosomes drift to the opposite or reverse poles
Mode of reproduction
Mitosis
Asexual
Meiosis
Sexual
Function
Mitosis
General growth and repair, Cell reproduction
Meiosis
Genetic diversity through sexual reproduction
Cytokinesis
Mitosis
Occurs in Telophase
Meiosis
Occurs in Telophase I and in Telophase II
