The 15 pages that link to Nondisjunction, each with the reason it gives.

• PolyploidyRelated: Errors in cell division can produce unreduced gametes that contribute to polyploidy.

• AneuploidyRelated: This segregation error produces daughter cells with unequal chromosome counts.

• HaploidRelated: Faulty segregation can leave gametes with abnormal chromosome numbers.

• DiploidRelated: It can produce cells with abnormal chromosome counts from diploid precursors.

• Down syndromeRelated: Nondisjunction during egg or sperm formation is a common route to trisomy 21.

• Homologous chromosomesCompared with: It occurs when homologues fail to separate at meiosis I.

• Chromosome theory of inheritanceRelated: Nondisjunction shows how abnormal chromosome transmission produces abnormal chromosome numbers.

• Klinefelter syndromeBroader topic: This chromosome-separation error can lead to an XXY chromosome complement.

• PloidyRelated: It can produce cells or gametes with abnormal chromosome numbers.

• AnaphaseCompared with: Faulty anaphase separation can leave daughter cells with abnormal chromosome numbers.

• Jérôme LejeuneRelated: It is a common route by which an extra chromosome 21 enters a cell.

• Pentasomy XRelated: Errors in chromosome separation can produce gametes or embryos with extra X chromosomes.

• Tetrasomy XRelated: Nondisjunction is a route by which an egg or sperm can carry extra X chromosomes.

• Chromosome abnormalityBroader topic: This segregation error is a common route to abnormal chromosome number.

• Trisomy 16Related: It can create an egg, sperm, or early embryonic cell with an extra chromosome 16.
