Explanation:
Difference between Mitosis and Meiosis
Types Mitosis Meiosis
Interphase Interphase – Chromosomes not yet visible but DNA has been replicated. Each chromosome replicates. The result is two genetically identical sister chromatids
Prophase Prophase –Each duplicated chromosome appear as two identical sister chromatids, The mitotic spindle begins to form. Chromosomes condense and thicken 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 Metaphase -The chromosomes assemble at the equator = metaphase plate Metaphase I Chromosomes adjust on the metaphase plate. Chromosomes are still intact and arranged as pairs of homologues
Anaphase 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. Anaphase I Sister chromatids stay intact. But homologous chromosomes drift to opposite or reverse poles.
Types of Reproduction Sexual Asexual
Occurs in Humans, animals, plants, fungi. All Organisms
Function Genetic diversity through sexual reproduction. General growth and cell reproduction, repair of the body.
Cytokinesis Occurs in Telophase I and in Telophase II. Occurs in Telophase
Karyokinesis Occurs in Interphase I. Occurs in
