But not everyone agrees that these traits are necessarily products of natural selection. Perhaps, skeptics have suggested, the observed fluctuations in allele frequencies are just routine ...

BACKGROUND: Desmosomal gene variants (DGVs) have been associated with a diverse spectrum of phenotypic manifestations within ...

is selection against homozygotes for a disadvantageous recessive allele, in linkage with ΔF508 in the Jewish Ashkenazi population. Such a mechanism might also explain the low frequency of the ...

Background Depression has been consistently linked to the onset of dementia, but the temporality and nature of this ...

Genotype and allele associations of controls with migraine and migraine subtypesThe IL1B−3953 C/T (rs1143634) genotype was associated with migraine (P = 0.038) and with a family history of migraine (P ...

40 A meta-analysis of 19 prospective cohort studies was limited by study heterogeneity and wide variability in both frequency of fish intake and ... effects remains to be established. The long natural ...

As a group, carriers of recessive disorders are slightly less healthy and have a reduced chance of having offspring. This disadvantage is greatest for carriers of a recessive gene for intellectual ...

accurately detects BRAF mutations in tumor biopsies and change in variant allele frequency (VAF) of BRAF mutation in ctDNA may be a surrogate marker for monitoring disease. The data is being ...

This paper presents valuable findings on the processing of sound mixtures in the auditory cortex of ferrets, a species widely used for studies of auditory processing. Using the convenient and ...

Biologists at the University of Massachusetts Amherst have released the first broad-scale, comparative, fine-grained analysis linking the amplitude, or volume, of a bird's song to its vocal frequency, ...
