Nondisjunction (Noun)

Meaning

Meiosis in which there is a failure of paired homologous chromosomes to separate; results in an abnormal number of chromosomes in the daughter cells.

Classification

Nouns denoting natural processes.

Examples

  • Nondisjunction is a type of error that can occur during meiosis, resulting in gametes with an abnormal number of chromosomes.
  • During meiosis I, a failure of nondisjunction in homologous chromosome separation can lead to trisomy in offspring.
  • Chromosomal abnormalities caused by nondisjunction during meiosis are associated with genetic disorders such as Down syndrome.
  • A major cause of birth defects and infertility, nondisjunction affects the number of chromosomes in gametes, which in turn can cause abnormalities in offspring.
  • Meiotic nondisjunction, specifically during the first meiotic division, often leads to chromosomal aneuploidy, or having an abnormal number of chromosomes in the daughter cells.
