Example sentences for: achiasmatic

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

  • The rec12 mutant meioses are achiasmatic and would thus be expected to suffer chromosome segregation errors during meiosis I. To gain insight into this possibility, asci from meiotic cultures were stained with a DNA specific fluorescent dye (DAPI) and visualized by differential interference contrast (DIC) and fluorescence microscopy.

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

  • In the presence of Rec12-Y98F protein the checkpoint would be active, thereby allowing the achiasmatic chromosomes sufficient time to reorient and undergo distributive segregation.

  • In the absence of crossover recombination (chiasmata) and a backup distributive (achiasmatic) system for chromosome segregation, MI nondisjunction should occur and 100% of any resulting diploid spore colonies would be heterozygous for centromere linked markers (Figure 5B).

  • Second, catalytically-inactive Rec12 protein facilitates achiasmatic (distributive) segregation.
