Increased rates of homologue nondisjunction in Fzr1−/− oocytes. (A) Representative confocal image of a monastrol-induced spread from a meiosis II (MII) egg used for aneuploidy analysis. (B) Aneuploidy rates in fl/fl and Fzr1−/− oocytes matured in vitro. *p = 0.045; χ2. (C) Kinetochore counts from individual eggs scored in B. Rates of hyperploidy matched rates of hypoploidy in Fzr1−/− eggs (n.s., p = 0.41; χ2). (D) Nondisjunction prevailed over PSSC in aneuploid Fzr1−/− eggs (*p = 0.02; χ2). Parentheses in B and D indicate numbers of eggs analyzed. Scale bar in A, 2 μm.
