Relating to the cell division that makes eggs or sperm with half the chromosomes
  • adjective
  • /maɪˈɒtɪk/
  • Specialized
: meiótico
  • The most mature spermatogenic cell type present is the early spermatocyte, indicating an early meiotic arrest of spermatogenesis.
  • meiotic arrest
  • early meiotic

Examples

  • This study advances our clinical understanding of the molecular basis of early meiotic arrest as a cause of non-obstructive azoospermia.

    Academic text (2003)
  • A null mutation of Sycp3 in mice causes azoospermia with meiotic arrest.

    Academic text (2003)
  • And the response to that is that all the other genes wanted to 'cause these meiotic drivers to go away.

  • You can suppress the meiotic drive so you can punish the offenders.

  • Interpretation: We suggest that SYCP3 has an essential meiotic function in human spermatogenesis that is compromised by the mutant protein via dominant negative interference.

    Academic text (2003)
  • Another study of an accidental exposure of a female mouse control group to BPA from damaged polycarbonate cages showed that the exposure can result in meiotic abnormalities.

  • By contrast, examination of testis biopsy samples from the patients with the 643delA mutation showed a profoundly abnormal spermatogenic process due to complete early meiotic arrest.

    Academic text (2003)
  • No variants or single-nucleotide deletions were observed in the nucleotide sequences of the other meiotic-arrest patients or in the 75 pregnancy-proven fertile control individuals (p=0.039).

    Academic text (2003)
  • We identified the human SYCP3 gene on chromosome 12 and screened azoospermic men presenting with meiotic arrest and normal, pregnancy-proven fertile controls for mutations in SYCP3.

    Academic text (2003)
  • The process of meiotic division results in the formation of gametes, which are essential for sexual reproduction.

Morphology

meiotic = meiosis (transparent) = meiosis + ic

Formed by adding the adjective-forming suffix '-ic' to the noun 'meiosis'; learners who know 'meiosis' can readily infer 'meiotic' means 'relating to meiosis'.

Etymology

Meiotic comes from the Greek word meiosis and the root meio- meaning 'lessen' or 'make smaller'. So meiotic describes the special cell division that makes sex cells like sperm and eggs with 'less' genetic material, half the usual number of chromosomes.
