How can you use “nondisjunction” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • However, the frequency of MI nondisjunction observed is only half of that expected, suggesting the presence of a distributive (achiasmatic) system of chromosome segregation.

  • The value obtained in the rec12 mutants was 2.5-fold higher than the predicted random value, indicating that the segregation errors are not simply the consequence of random chromosome assortment (nondisjunction) occurring exclusively during one of the two meiotic divisions.

  • By applying mapping functions for aneuploid meiotic products [ 47 ] , we can set a lower limit of 22% and 29% MII nondisjunction for the rec12-117 and rec12-D15 meioses analyzed, respectively.

  • While the rec12-D15 (null) mutants frequently suffer MI nondisjunction, the rec12-Y98F (active site) mutants produce meiotic diploids with nearly normal MI segregation patterns (Figures 3, 5, Table 2).

  • Meiotic progression in spo11 ( rec12 ) null mutants of budding yeast is accelerated [ 29 ] , supporting our hypothesis that Rec12 may participate in an "MI nondisjunction checkpoint."
