The 24 pages that link to Aneuploidy, each with the reason it gives.

• MeiosisRelated: Nondisjunction during meiosis can produce gametes with an abnormal chromosome count.

• ChromosomeRelated: Chromosome counts identify aneuploidies such as trisomy 21.

• Prenatal diagnosisRelated: Aneuploidies are among the genetic conditions commonly assessed during pregnancy.

• MitosisRelated: Mitotic segregation errors can leave daughter cells with abnormal chromosome counts.

• PolyploidyCompared with: It separates whole-set changes from changes to particular chromosomes.

• Preimplantation genetic testingRelated: A major testing aim is identifying embryos with detectable chromosome-number abnormalities.

• HaploidCompared with: A haploid cell has a complete set; aneuploid cells have an incomplete or extra chromosome complement.

• DiploidCompared with: It departs from the balanced chromosome pairs expected in diploid cells.

• Down syndromeNarrower topic: Down syndrome is a specific aneuploidy involving chromosome 21.

• Homologous chromosomesRelated: Faulty homologue separation can produce gametes with abnormal chromosome counts.

• NondisjunctionBroader topic: It is the characteristic chromosome-count outcome when nondisjunction affects a cell lineage.

• OogenesisRelated: Long meiotic arrests can increase the risk of chromosome segregation errors in oocytes.

• Gene dosageNarrower topic: Aneuploidy changes dosage for many genes at once.

• Theodor BoveriRelated: Boveri connected abnormal chromosome complements with disrupted development and later proposed a link to cancer.

• Antifungal resistanceRelated: Chromosome-copy changes can alter expression of genes involved in antifungal susceptibility.

• CytogeneticsBroader topic: Detecting aneuploidy is a major use of chromosome counting in clinical cytogenetics.

• Chromosomal translocationCompared with: Aneuploidy describes chromosome dosage, which can result from unbalanced segregation but is not itself a translocation.

• CentromereRelated: Centromere or kinetochore segregation errors can produce aneuploid daughter cells.

• Mitotic spindleRelated: Faulty spindle attachment or segregation can produce cells with abnormal chromosome counts.

• PloidyCompared with: It contrasts with ploidy changes, which concern whole sets.

• Somatic mosaicismRelated: Aneuploidy can occur in only a subset of cells, creating chromosomal mosaicism.

• Pentasomy XNarrower topic: Pentasomy X is an aneuploidy involving five copies of one sex chromosome.

• Tetrasomy XNarrower topic: Tetrasomy X is an aneuploidy with two extra X chromosomes.

• Chromosome abnormalityBroader topic: It describes the numerical changes that result when particular chromosomes are missegregated.
