Meiosis
Differences from Mitosis
-
-
-
-
Chromosome Number
Mitosis produces daughter cells that are diploid (i.e., they have the same number of chromosomes as the parent cell)
Meiosis produces daughter cells that are haploid (i.e., they have half the number of chromosomes as the parent cell)
Function
Mitosis is used for growth, repair, and asexual reproduction
-
Crossing Over
In Mitosis, no crossing-over occurs
In Meiosis, crossing-over occurs during Prophase I, leading to genetic recombination
Homologous Chromosomes
In Mitosis, homologous chromosomes do not pair up
In Meiosis, homologous chromosomes pair up during Prophase I
Importance
Sexual Reproduction
Production of Gametes
Meiosis is the process that produces gametes, which are the sex cells (sperm in males and eggs in females)
-
Chromosome Reduction
Meiosis reduces the number of chromosomes in a cell by half. This reduction is critical for sexual reproduction.
Genetic Diversity
Meiosis ensures genetic diversity by producing genetically unique cells. These unique cells are necessary for the survival of a species over time.
