Abstract

Competitive sperm Both competition and cooperation between sperm have been well documented, but can individual sperm discriminate between kin, with whom they should cooperate, and non-kin, with whom they should not? Heidi Fisher and Hopi Hoekstra show that when the sperm of two deer mice species are mixed, they aggregate preferentially with sperm from their own species. In mixtures between individuals of the same species, sperm from a monogamous species do not discriminate kin from non-kin, whereas sperm from a promiscuous species do.
