The X chromosome harbored the highest average incidence of variations with three copy number alterations per sample, but this corresponded to a relative increase in X chromosome alterations of slightly greater than three-fold above the predicted value.
Firstly, the issue of a MAF threshold was not addressed, so it is not clear whether loci associated with a low MAF were discarded or included; the effect of their inclusion would be to generate false associations caused by the co-incidence of variation for a trait and a statistically under-represented allele.
Therefore, the incidence of numerical variation in mobile vertebrae and the presence of transitional vertebrae in their study was even lower than in ours.
The best configuration from the economic point of view is indicated, and the incidence of the variation of the absorption chiller and storage systems sizes on the feasible investment cost of the CHP unit is evaluated and discussed as well.
Assuming seven cervical and 12 thoracic vertebrae, they found a 20%% incidence of numerical variation, with 14.5 % of all patients having six lumbar vertebrae, 5.3 % having four, and one patient (0.13 %) having three.
In taxa where more populations were collected, the incidence of intraspecific variation of genome size was evaluated.
Genetic polymorphisms are widespread in many populations [ 47, 59], but the incidence of cryptic variation is usually unknown for wild populations [ 14, 15].
In interior Alaska, 5 of 46 M. rutilus individuals had complete post-palatal bridges suggesting a low incidence of natural variation within this character in the northern red-backed vole.
Due to the regeneration methods, a higher incidence of somaclonal variation should be expected in plants derived from male cells [ 34]; moreover, the callus stage has generally been proved to generate somaclonal variants in citrus [ 35, 36].
