Answer 2

$\bold{\boxed{Answer}}$

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.

• Each chromosome replicates. The result is two genetically identical sister chromatids (However, do note that interphase is technically not a part of mitosis because it takes place between one mitotic phase and the next)

• 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 -The chromosomes assemble at the equator at the metaphase plate.

• 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.

• Asexual Reproduction.

• All the cells

• General growth and repair, Cell reproduction.

• Occurs in Telophase

Meiosis:-

• 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)

• Metaphase I Chromosomes adjust on the metaphase plate. Chromosomes are still intact and arranged as pairs of homologues.

• Anaphase I Sister chromatids stay intact. However, homologous chromosomes drift to the opposite or reverse poles.

• Sexual Reproduction.

• Reproductive cells.

• Genetic diversity through sexual reproduction.

• Occurs in Telophase I and in Telophase II
