Part of CB-03 — Cell Cycle, Mitosis & Meiosis

Comparison Note: Mitosis vs. Meiosis

by Notetube Official191 words6 views
FeatureMitosisMeiosis
Number of divisions12 (meiosis I + II)
Daughter cells24
Ploidy of daughtersDiploid (2n)Haploid (n)
DNA content of daughters2C1C
Genetic compositionIdentical to parentGenetically diverse
SynapsisAbsentPresent in prophase I
Crossing overAbsentPresent in pachytene
ChiasmataAbsentPresent (visible in diplotene)
Bivalent formationAbsentPresent (zygotene)
Homologue separationDoes not occurAnaphase I
Sister chromatid separationAnaphaseAnaphase II
Cell typeSomatic cellsGerm cells (gonads)
SignificanceGrowth, repair, asexual reproductionGamete formation, genetic variation
SpindleAmphitelic (sister kinetochores to opposite poles)Meiosis I: syntelic for homologues; meiosis II: amphitelic

Key NEET Distinction: The defining difference between the two divisions is that Meiosis I separates homologous chromosomes (reductional), while Mitosis and Meiosis II separate sister chromatids (equational).
