Examplesofchromatidchromatid We consider this unsuccessful development of reconstituted eggs to be due mainly to abnormal spindle formation and/or unequal distribution of chromatids, as described above. From theCambridge English Corpus One of the spores carries a mutant allele with a structure showing that a duplication in onechromatidhad been transferred to a homologouschromatid. From theCambridge English Corpus Chromatids carrying the smaller allele are represented in black, and chromatids carrying the larger allele are represented in grey. From theCambridge English Corpus There were no differences in the distribution of the different types of chromosomal andchromatidaberrations between the two storage groups. From theCambridge English Corpus Two molecular processes generating variability have been proposed : replication slippage due to slipped-strand mispairing and unequal recombination between homologous chromosomes (or chromatids). From theCambridge English Corpus Separate chromatids can also be resolved in the long arms of these chromosomes (arrowheads). From theCambridge English Corpus In each cell analysed, the number of chromosomes and/or chromatids was counted at x1250 magnification to provide data for calculating aneuploidy. From theCambridge English Corpus Fourteen hyperhaploidies were found, seven involving additional single chromatids. From theCambridge English Corpus In the diagram onechromatidhas segregated with the whole chromosome and the other is alone. From theCambridge English Corpus There were seven examples of extra chromatids and four of missing ones, in ten oocytes. From theCambridge English Corpus The somatic chromosomes consist of two sister chromatids. From theCambridge English Corpus An oocyte classified as 201/2 contains 20 dyads and onechromatidor one-half dyad. From theCambridge English Corpus The first requirement is for close pairing of homologous chromosomes, followed by recombination between non-sister chromatids. From theCambridge English Corpus In addition, no allele has been found in which the exchange point between homologous chromatids was included in a duplication. From theCambridge English Corpus Differential inhibition of sisterchromatidcondensation induced by 5-azadeoxycytidine in human chromosomes.
