The present study revealed that the size polymorphism between chromosome III homologues results from an unequal exchange of chromosome ends.
However, pairwise and multiple comparisons of all sequences provided evidence of recombination that has caused the exchange of chromosome fragments of varying length, up to ~15 kbp.
This does not end with the transfer of DNA and the exchange of chromosomes.
The evolutionary success of eukaryotic organisms crucially depends on the capacity to produce genetic diversity through reciprocal exchanges of each chromosome pair, or crossovers (COs), during meiosis.
The only outcome that generates a linkage between the homologs is a CO event, in which exchanges of homologous chromosome arms occur.
Different types of chromosomal damage caused by asbestos fibers may be observed in asbestos-exposed cells, including chromosomal breaks and fragments (micronuclei), lagging chromosomes, exchange of chromosomal segments between two chromosomes and chromosomal missegregation.
MEIOTIC recombination is the exchange of chromosomal regions between homologous chromosomes during meiosis, a specialized type of cell division in sexually reproducing eukaryotes (Lao and Hunter 2010; Lichten and De Massy 2011; Pradillo and Santos 2011).
In an effort to determine breakpoints between the wAna genomic fragments and the host genome, we treated those breakpoints as translocation events (i.e., exchange of chromosomal DNA between nonhomologous chromosomes) and used the program Lumpy ver 0.2.6 (Layer et al. 2014) to detect the breakpoints between the wAna genome and the host genome.
Crossover is an operator used to explore new solutions in search space, and it is responsible to exchange parts of chromosomes among selected parents.
The repair of any given meiotic DSB can result in either reciprocal exchange of the chromosome arms flanking the break (a crossover), or no exchange of flanking arms (a noncrossover or parental configuration).
