| "The implications of these findings is that an individual is able to strike an optimal balance between inbreeding and outbreeding by learning about is immediate kin and mating with a member of the opposite sex that is slightly different from its immediate kin. What such a balance might amount to in practice has previously been uncertain. I report here that Japanese quail of both sexes, having been reared with their siblings, subsequently prefer a first cousin of the opposite sex. ( Bateson, P. (1982) Preferences for cousins in Japanese quail Nature 295: 236) [note: choice between sibling, sibling novel, 1st cousin novel, 3rd cousin novel, and non related novel stranger.]
