Data from: Is there indirect selection on female extra-pair reproduction through cross-sex genetic correlations with male reproductive fitness?
- 负责人:
- Reid, Jane
- DOI:
- doi:10.5061/dryad.p6df410
- 摘要:
- indirect selection may consequently have limited capacity to drive evolution of female extra-pair reproduction, or hence underlying polyandry, in systems wher
