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-D15 (null) mutants are achiasmatic (Table 1) and, as anticipated, exhibit a high frequency of MI nondisjunction (Figures 3, 5, Table 2).
A meiotic checkpoint could provide additional time for missegregating chromosomes to correct their erroneous wanderings during MI [ 10 ] . We propose two likely mechanisms by which the Rec12 protein improves the MI segregation of achiasmatic chromosomes.
Second, catalytically-inactive Rec12 protein facilitates achiasmatic (distributive) segregation.
A 250-fold reduction in recombination would leave less than 0.1 crossovers per chromosome, so all three chromosomes in most of the rec12 mutant meioses are achiasmatic.
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.
