The use of molecular techniques for parentage analysis has been a booming science for
over a decade. The most important technological breakthrough was the introduction of …

Male pregnancy in seahorses, pipefishes and sea dragons (family Syngnathidae)
represents a striking reproductive adaptation that has shaped the evolution of behaviour and …

Stalk-eyed flies in the genus Teleopsis carry selfish genetic elements that induce sex ratio (SR)
meiotic drive and impact the fitness of male and female carriers. Here, we assemble and …

Environmental estrogens have been shown to affect populations of aquatic organisms in
devastating ways, including feminization of males, alterations in mating behaviors, and …

Empirical studies of sexual selection often focus on events occurring either before or after
mating but rarely both and consequently may fail to discern the relative magnitudes and …

Experimental evolution provides an integrative method for revealing complex interactions
among evolutionary processes. One such interaction involves sex-linked selfish genetic …

Although sex chromosome meiotic drive has been observed in a variety of species for over
50 years, the genes causing drive are only known in a few cases, and none of these cases …

Sex‐linked segregation distorters cause offspring sex ratios to differ from equality. Theory
predicts that such selfish alleles may either go to fixation and cause extinction, reach a stable …

Just as mating patterns can promote speciation or hybridization, the presence of hybridization
can shape mating patterns within a population. In this study, we characterized patterns of …

The reproductive mode of facultative parthenogens allows recessive mutations that accumulate
during the asexual phase to be unmasked following sexual reproduction. Longer periods …
