Mitosis vs. Meiosis

Flashcards
0/10
Phase: Prophase in Mitosis
Chromosomes condense, but no pairing occurs between homologous chromosomes; nuclear envelope breaks down; spindle apparatus forms.
Phase: Prophase I in Meiosis
Homologous chromosomes pair and exchange segments (crossing over); nuclear envelope breaks down; spindle apparatus forms.
Number of Divisions
Mitosis involves one division resulting in two daughter cells, whereas meiosis involves two divisions resulting in four daughter cells.
Genetic Diversity
Meiosis increases genetic diversity through independent assortment and crossing over, whereas mitosis produces genetically identical cells.
Function in the Organism
Mitosis is for growth, repair, and asexual reproduction; meiosis is for sexual reproduction and production of gametes.
Chromosome Number in Daughter Cells
Daughter cells from mitosis are diploid (2n); daughter cells from meiosis are haploid (n).
Phase: Metaphase in Mitosis
Chromosomes line up at the metaphase plate individually, and microtubules attach to kinetochores.
Phase: Metaphase I in Meiosis
Homologous chromosome pairs line up at the metaphase plate together, and microtubules attach to kinetochores.
Crossover and Genetic Variation
No crossover in mitosis, so no genetic variation introduced; meiosis has crossover in Prophase I, introducing genetic variation.
Role of Cohesin Proteins
Cohesin proteins are removed from chromosome arms in mitosis during anaphase; in meiosis, cohesins are removed from chromosome arms in Anaphase I and from centromeres in Anaphase II.
