| Pronunciation (US): |  | (GB): | |
Irregular inflected form: meioses
I. (noun)
Sense 1
Meaning:
Understatement for rhetorical effect (especially when expressing an affirmative by negating its contrary)
Example:
saying 'I was not a little upset' when you mean 'I was very upset' is an example of litotes
Synonyms:
Classified under:
Nouns denoting communicative processes and contents
Hypernyms ("meiosis" is a kind of...):
understatement (a statement that is restrained in ironic contrast to what might have been said)
rhetorical device (a use of language that creates a literary effect (but often without regard for literal significance))
Sense 2
Meaning:
(genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants)
Synonyms:
meiosis; miosis; reduction division
Classified under:
Nouns denoting natural processes
Hypernyms ("meiosis" is a kind of...):
cell division; cellular division (the process in reproduction and growth by which a cell divides to form daughter cells)
Meronyms (parts of "meiosis"):
anaphase (the stage of meiosis or mitosis when chromosomes move toward opposite ends of the nuclear spindle)
cytokinesis (organic process consisting of the division of the cytoplasm of a cell following karyokinesis bringing about the separation into two daughter cells)
karyokinesis (organic process consisting of the division of the nucleus of a cell during mitosis or meiosis)
metaphase (the second stage of meiosis)
prophase (the first stage of meiosis)
segregation ((genetics) the separation of paired alleles during meiosis so that members of each pair of alleles appear in different gametes)
telophase (the final stage of meiosis when the chromosomes move toward opposite ends of the nuclear spindle)
Domain category:
genetic science; genetics (the branch of biology that studies heredity and variation in organisms)
Hyponyms (each of the following is a kind of "meiosis"):
nondisjunction (meiosis in which there is a failure of paired homologous chromosomes to separate; results in an abnormal number of chromosomes in the daughter cells)
Derivation:
meiotic (of or relating to meiosis)
Context examples:
In vertebrates, immature oocytes are arrested at the PI (prophase of meiosis I).

(MOS Gene, NCI Thesaurus)
There are two main types of cell division depending on what happens to the chromosomes: mitosis and meiosis.
(Cell division, The Titi Tudorancea Bulletin)
One of the two side by side replicas produced by chromosome replication in mitosis or meiosis.
(Chromatid, NCI Thesaurus)
A gene duplication abnormality may occur by gene amplification, random breakage and reunion, retrotransposition or unequal crossing-over at meiosis.
(Gene Duplication Abnormality, NCI Thesaurus)
Defects in MMR are associated with genome-wide instability, predisposition to certain types of cancer including HNPCC, resistance to certain chemotherapeutic agents, and abnormalities in meiosis and sterility in mammalian systems.
(Mismatch Repair Pathway, NCI Thesaurus/KEGG)
This protein plays a role in both the modulation of microtubule structure and facilitation of chromosome segregation during mitosis and meiosis.
(Aurora Kinase B, NCI Thesaurus)
This allele, which encodes serine/threonine-protein kinase 12, plays a role in chromosome segregation modulation during cellular mitosis and meiosis.
