Example sentences for: achiasmatic

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

If Rec12 were required for such a checkpoint, the null mutants would be achiasmatic, would fail to delay for the time period required to establish distributive segregation, and would consequently undergo high rates of MI nondisjunction.
We propose that the Rec12-Y98F protein facilitates distributive segregation of achiasmatic chromosomes during MI.
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 female meioses of D. melanogaster , heterochromatic pairing of homologs can substitute for chiasmata to ensure bipolar spindle attachment of bivalents and subsequent distributive segregation [ 4 5 6 8 ] . Rec12 may serve a similar role in maintaining a paired (or pseudo-paired) state between achiasmatic chromosomes prior to the first meiotic division.
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.
