WebNondisjunction during mitosis can contribute to the development of some forms of cancer, e.g., retinoblastoma (see below). Chromosome nondisjunction in mitosis can be attributed to the inactivation of topoisomerase II, condensin, or separase. Meiotic nondisjunction has been well studied in Saccharomyces cerevisiae.
