The genetic mating system of a sea spider with male-biased sexual size dimorphism: evidence for paternity skew despite random mating success
{{output}}
Male-biased size dimorphism is usually expected to evolve in taxa with intense male-male competition for mates, and it is hence associated with high variances in male mating success. Most species of pycnogonid sea spiders exhibit female-biased size dimorphism,... ...
