Many studies have revealed that the modification states of the histones are not evenly distributed among all possible states but rather reflect correlations of the modified forms of specific residues, yet there is an absence of biochemical studies that provide mechanisms that clearly account for the generation of only a small subset of the possible states.
In older generations, while only a small proportion came from families that could afford private education, for those who could, it was common to be sent at age five.
Yet, it would be possible to scale to larger sizes by using column-generation techniques, whereby only a small subset of the generated set of routes is initially inserted in the problem, and new ones are inserted as needed using standard duality arguments.
In the nematode Caenorhabditis elegans it has been shown that phenotypes induced by RNAi can last only for two or three generations [ 52], and only a small subset of genes (13/171) that could be inheritably silenced for longer periods of time [ 53].
However, the size of the trials will remain limited as the generation of molecular data is only a small fraction of the cost and overall costs of large clinical trials remain astronomical.
For line LFP, the level of pecking behaviour was constantly low during the 11 generations of selection and showed only a small and almost undetectable decrease in the mean number of FP bouts over generations.
This study shows that a marker density of 8Ne/M seems sufficient for the estimated marker effects to persist over five generations with minimum bias and only a small reduction in selection accuracy.
It has been determined that for the generation of a protective ozone layer only a small amount of oxygen (0.1 of the present atmospheric levels) is sufficient (Kasting and Donahue 1980).
The cumulative total number of distinct QTNe across the 20 generations was as low as 14 when only a small number of QTNe were performed per generation and these edits were focussed on only a few sires, and was as high as 1252 when a large number of QTNe were performed per generation and on a small number of sires.
However, generation of tetramers is expensive and currently only a small proportion of HLA class II molecules are available in this form.
