Sexual dimorphism in
pheromone receptor expression has been reported in rats [20], but the best defined mammalian example is the detection of the male - specific pheromone ESP1 by Vmn2r116, which is capable of eliciting lordosis behavior specifically in female mice.
Not exact matches
Individuals with low
expression of a
pheromone receptor are more inclined to explore and are fitter in environments with scattered food resources.
Thus diversity in
receptor expression can explain differences in odor sensitivity, but does not appear to dictate whether sex
pheromones are differentially detected by males or females.
