Both common and specific genetic factors influenced the bands, with common genetic and specific Genetic factors having more influence in the occipital and frontal regions, respectively. Expand
Twin study of the heritability of recognition thresholds for sour and salty taste.
This result suggests that environment plays a larger role than genetics in determining individual differences in recognition thresholds for saltiness, on par with that of sensitivity to the bitter compounds 6-n-propylthiouracil and phenylthiocarbamide. Expand

The perceived bitterness intensity for bitter solutions of propylthiouracil (PROP), sucrose octa-acetate (SOA), quinine HCl and caffeine were examined and the results suggest that the perception of PROP and the Perception of SOA,quinine, and caffeine are influenced by two distinct sets of genes.

Environmental Effects Exceed Genetic Effects on Perceived Intensity and Pleasantness of Several Odors: A Three-Population Twin Study
Estimating the relative contributions of genetic and environmental effects to variation in the perceived intensity and pleasantness of cinnamon, chocolate, turpentine, and isovaleric acid (sweaty) odors by quantitative genetic modeling of odor rating data from 856 twin individuals promotes the importance of inter-individual variation in odor exposures and olfactory plasticity to odor perception.

Replication of linkage and association of PROP perception to chromosome 7 and suggestion of novel loci on chromosome 6
Self‐Ratings of Olfactory Function Reflect Odor Annoyance Rather than Olfactory Acuity
Self‐ratings of olfactory function often correlates poorly with results of objective smell tests, and ratings relative to self‐rating of odor annoyance, to odor identification ability, and to mean perceived intensity of odors are explored. Expand
Genetic and Environmental Contributions to Perceived Intensity and Pleasantness of Androstenone Odor: An International Twin Study
We estimated the genetic and environmental components of variation in perceived intensity and pleasantness of androstenone, an odorous compound showing specific anosmia, by modeling twin data from… Expand
