Sentence examples for an inversion loop from inspiring English sources
The only way uninverted and inverted segments can pair is by forming an inversion loop.
Neither showed any recombinant chromosomes in sperm, suggesting that either an inversion loop was not formed or that crossing over was suppressed within the loop.
The genome of S. pennellii is 20 30% larger than the tomato genome, and electron microscopic examination of SC spreads from an F1 hybrid revealed a large segment of foldback synapsis, a small inversion loop, and at least five SCs with mismatched kinetochores (Anderson et al. 2010).
PMC's in A II with the presence of bridges and segment in each of the two cells of a dyad (Fig. 1F), could be an evidence of heterozygous inversions with 3 crossover points within the inversion loop [ 17], where similar aberrations were reported for Agave stricta [ 9].
In inner loop these body rates are tracked using faster dynamic inversion loop by generating the necessary control surface deflections.
Because recombination is not suppressed in these boundary regions in the absence of an inversion (Stevison and Noor 2010), it is not immediately obvious how recombination suppression would extend this far outside of the inversion loop.
Therefore, if two crossover events occur within the inversion loop created at meiosis, they are more likely to span the center of the inversion than segments closer to the inversion breakpoints (Navarro et al. 1997).
Indeed, genetic exchange between inverted arrangements may be possible via double cross-over events in inversion loops, with the probability of recombination increasing with physical distance from the inversion breakpoints (Navarro et al. 1997; Faria and Navarro 2010; Stevison et al. 2011).
The t-inversions suppress genetic recombination in the region and prevent homologous synapsis at the sequence level as evidenced by the absence of inversion loops of synaptonemal complexes in pachytene nuclei (Tres and Erickson 1982).
Following the drop, the train goes through a non-inverting loop (meaning that the train doesn't go through an inversion), which is nicknamed "The Double Take".
