This discrepancy can be explained by the exceptional high losses suffered by some of the larger operations surveyed.
The numerical difference between leukemia risks and solid cancer risks could be explained by the exceptional radiosensitivity of hematopoietic tissues in utero compared to other tissues.
Most of diagnostic di- and trinucleotides could be explained by the above two rules, but there were various exceptional cases for tetranucleotides, indicating the presence of factors other than the two rules.
However, loss of stamens in the 'bud-flowering' phenotype is an exceptional flower organ modification that cannot be explained by modified spatial expression of known organ identity genes.
Part of this may be explained by selection of cases with the clinical ethical analysis focusing on exceptional cases whilst the empirical studies take mixed populations of patients with varying levels of depression and different decisions (research and treatment).
Xenopus MBD3 is exceptional in its binding to methylated CpG which can be explained by the difference of an amino acid residue within the MBD (Lys30) important for DNA binding [ 31].
These phenomena, including the expansions of plant mitochondrial genomes and the occasional exceptional species with high mutation rates accompanied by still more genome expansion can all be explained by a model of DNA repair and recombination.
The exceptional ion-exchange selectivity for ClO4− was explained by the process of dominant accumulation, quick insertion of anions, and the sluggish mobility of ClO4− inside the membrane.
The exceptional performance of Ag/ZrO2 NP) for soot oxidation in loose contact mode was explained by relatively good catalyst-soot contact state and effective migration of active oxygen species from the catalyst to soot.
The exceptional selection systems that originally suggested stress-induced mutagenesis may also be explained entirely by natural selection, acting on mutants that arise at standard mutation rates.
