| On average, each double-crossover bivalent produces one double-crossover chromosome in the absence of chromatid interference. |
| Gap: an achromatic lesion smaller than the width of one chromatid, and with minimum misalignment of the chromatids. |
| One is the nonreciprocal transfer of information of both DNA strands of a donor chromatid to a chromatid of the homologous chromosome. |
| Ring chromosomes, chromatid exchanges and polyploidies were also observed at some treatments. |
| The analysis of structural aberrations included chromatid and chromosome breaks, appearance of acentric fragments, dicentric chromosomes and chromatid exchanges. |
| A double crossover involving one linear chromatid and both chromatids of the circular chromosome generates a linear trimer. |
