Males and females of many animal species have wildly different physical traits. For example, male birds often have bright plumage to attract females while female birds often have plain plumage to hide themselves during the breeding season. In this situation, males and females share nearly all of their genomes, however, they each have to deal with very distinct selective pressures. This tug of war between different sexes on shared genes is called intralocus sexual conflict (IASC), which would displace the sexes from their distinct phenotypic optima as a result of sex-specific selection on sexually homologous (‘shared’) traits that regulated by a shared genetic machinery. IASC can be resolved through many mechanisms, including gene duplication, sex linkage, alternatives splicing and genomic imprinting. This JC would focus on the empirical evidence supporting IASC, how is IASC resolved, and the interaction between sexual selection and sexual conflict.
