Parents suppress reproduction and stimulate dispersal in opposite-sex juvenile white-footed mice
Article Abstract:
The dispersal of young among white-footed mice (Peromyscus leucopus) results from an instinctive effort to prevent the inbreeding that would occur if too many mice mated with their parents. The experimental removal of one mouse parent prevented the opposite-sex offspring from leaving the nest while the presence of both parents deterred the young from reproducing. These observations show that the inbreeding hypothesis is preferable to the alternative view which explained juvenile sex-biased dispersal in terms of preventing reproductive competition between parents and offspring.
