 In this set, individuals were more likely to choose non-related over related conspecifics.For example, in a study by Krackow et al., male wild house mice were set up in an arena with four separate openings leading to cages with bedding from conspecifics.The conspecifics exhibited a range of relatedness to the test subjects, and the males significantly preferred the bedding of non-siblings to the bedding of related females.
