The localization cues ITD and ILD are processed in parallel pathways in the brainstem [16] [18], where neurons are narrowly tuned to sound frequency (Reviews: [4], [5]).
The ability to replenish reserves of sperm and seminal fluid likely further constrains male mating frequency (reviewed in [ 10]).
Studies in a broad array of species suggest that as callers experience an increase in arousal, their vocalisations become longer and higher in frequency (reviewed in Briefer 2012).
Mouse knockout models have demonstrated that MSH2-/-, MSH3-/-, MLH1-/- and PMS2-/ leads to a high frequency of MSI while MSH6-/ and PMS1-/ cause a low frequency (reviewed by Wei et al. [ 10]).
Balancing selection operates through either negative frequency-dependent selection, in which the relative fitness of individual alleles is influenced by their frequency (reviewed in [ 6]), or via heterozygote advantage.
In humans, it is clear that spontaneous reactivation leading to the shedding of virus in the genital mucosa occurs at high frequency (reviewed by Koelle & Corey, 2008; Schiffer & Corey, 2009).
Early experiments unequivocally demonstrated the chromosome theory of heredity, provided important observations regarding the role of chromosome sites (including the centromere and the teleomere), and constructed the first meiotic map based on recombination frequency (reviewed in Lake and Hawley 2012).
During the day, when photons are not limiting, the system is better served by integrating over smaller areas, so it can resolve image details; in this case, the shift is toward high spatial frequencies (reviewed in [56], [57]).
Several other genes, such as APC, CDH1, CDKN2A, RASSF1A, and RARB2 (Graff et al, 1995; Jarrard et al, 1997; Nakayama et al, 2001; Liu et al, 2002; Maruyama et al, 2002; Yamanaka et al, 2003), have been reported to be hypermethylated in prostate cancer with various frequencies (reviewed in Schulz and Seifert, 2003).
