No information is available on the number of patterns in the book that have even this very coarse sort of quantitative data, but impressionistically, it appears to be only a fraction of the patterns presented in the book.
In brief, we make two points about these expression patterns as they relate to the behavioral activation phenotypes: 1) Only a fraction of the cells in each expression pattern are responsible for the phenotypes as GAL4 lines do not necessarily target functionally related neurons.
The problem is made particularly difficult when only a fraction of the recorded neurons are involved in the pattern.
Although this result suggests that spores are mainly dispersed locally, it appears as though a fraction of the dwarf males break the general pattern.
When interphase GSCs were stained for CD133, we found a polarized staining pattern in a fraction of the cells.
It is intuitive that the complexity of this algorithm can be reduced: given a recombination pattern, only a fraction of the genome is passed on and all genotypes that agree on that fraction contribute identically.
Since the gene expression patterns represent an average of all of the cells within the bulk tumor tissue, it is possible that different subpopulations display various components of the metastatic pattern, but only a fraction of the entire program.
We conclude that while for a fraction of patterns the start was precisely synchronized, overall pattern spikes were not precisely synchronized but tended to co-occur in a loose manner because of firing rate co-modulation.
A small fraction of the valency patterns listed in the book contain very non-granular indications of their relative frequencies: "Patterns for which only a few instances could be found in the corpus are labelled rare" (p. XL).
In interphase, a fraction of Rab24 presents a reticular pattern following the microtubules distribution whereas this protein localizes to the mitotic spindle at metaphase, and to the midbody and cleavage furrow during cytokinesis.
