Importance of Meiosis.
All the steps and other extra information.
Meiosis
DefinitionA type of cellular reproduction in which the number of chromosomes are reduced by half through the separation of homologous chromosomes, producing two haploid cells.
FunctionGenetic diversity through sexual reproduction.
Type of ReproductionSexual
Occurs inHumans, animals, plants, fungi.
GeneticallyDifferent
Crossing OverYes, mixing of chromosomes can occur.
Pairing of HomologsYes
Number of Divisions2
Number of Daughter Cells 4 Daughter cells
Chromosome NumberReduced by half.
Steps(Meiosis 1) Prophase I, Metaphase I, Anaphase I, Telophase I; (Meiosis 2) Prophase II, Metaphase II, Anaphase II and Telophase II.
Mitosis
A process of asexual reproduction in which the cell divides in two producing a copy, with the same number of chromosomes in each resulting diploid cell.
Function: Cellular reproduction
Type of reproduction: Asexual
Occurs in: All organisms
Genetically: Identical
Crossing over: No, Crossing over does not occur during any replication
Numer of divisions: 1
Number of daughter cells: 2 daughter cells
Chromosome number: remains the same
Steps: Prophase, Metaphase, Anaphase, Telophase.
