Abstract

Female three-spined sticklebacks Gasterosteus aculeatus preferred odour stemming from males with a nest over ‘neutral’ water and odour from males without any nest in an experimental flow channel. Males without any nest were preferred over females when either having the same major histocompatibility complex (MHC) class lI genotype or being unattractive in respect to MHC class II alleles.
