Paper Context: In B. mori females, however, the olfactory code was much more variable from individual to individual than in the five other insect species investigated and was thus less reliable. Hence, changes in the neural coding of environmental odorants in domesticated silkmoth females could occur because they had no impact on the survival of offspring. Thus, the amplitude of antennal responses (linked to the W chromosome) and the representation of odours in the brain (not linked to the W chromosome) seem to be controlled by genes located on different chromosomes.
