Moreover, previous attempts to show a link have come up with a much weaker correlation between the two phenomena.
There is a weaker correlation between answering tier-1 questions on light propagation and answering tier-1 questions on visibility.
With respect to their descendants, Antecol (2000) also reported a positive, though weaker, correlation between US and source country participation for "second and higher generation" immigrants defined by their answer to the 1990 Census question on ancestry.
Importantly, those global changes are not random: they lean towards a weaker correlation between slack and price pressures.
Another explanation for weaker correlation between genes is the definitions of function provided by GO terms.
Similarly, we connected HDF proteins that significantly share indirectly interacting viral proteins (P<0.01) and found a similar, yet weaker correlation between pathway involvement and indirectly targeting viral proteins (inset, Fig. 3D; r = 0.26, P<0.1).
If this is true, we expect to see much weaker correlation between mRNA and protein expression differences observed between species than between the ones observed in response to functional stimuli.
For genes showing the features exemplified by BTN3A2, we observed a weaker correlation between the more common allele and the chimpanzee nucleotide, i.e., a more significant proportion of the rare alleles matched the ancestral nucleotides.
In contrast to the strong correlation between ORF and mRNA length, and the small correlation between ORF and 5'-UTR length that we identified in Refseq, the H-Inv clones showed a weaker correlation between ORF and clone length and a moderately negative correlation between ORF and 5'-UTR length.
Indeed, the weaker correlation between 5' homology block length and the number of L/A breakpoints observed at that site compared to that for C/L or C/A breakpoints suggests that additional factors affect template switching and may suggest a lesser role (or no role) for HR in the intrachromosomal template-switch between LYP1 and ALP1.
Reid et al. (2009) found a weaker correlation between diabetes prevalence and these variables (coefficients < 0.3).
