Natural and Engineered Sex Ratio Distortion in Insects
Frontiers in Ecology and Evolution, 2022 Insects have evolved highly diverse genetic sex-determination mechanisms and a relatively balanced male to female sex ratio is generally expected. However, selection may shift the optimal sex ratio while meiotic drive and endosymbiont manipulation can ...

Conflict over condition-dependent sex allocation can lead to mixed sex-determination systems [PDF]
, 2014 Theory suggests that genetic conflicts drive turnovers between sex-determining mechanisms, yet these studies only apply to cases where sex allocation is independent of environment or condition.

Haploid selection, sex ratio bias, and transitions between sex-determining systems.
PLoS Biology, 2018 Sex determination is remarkably dynamic; many taxa display shifts in the location of sex-determining loci or the evolution of entirely new sex-determining systems. Predominant theories for why we observe such transitions generally conclude that novel sex-

Modeling and forecasting sex differences in mortality: a sex-ratio approach
Genus, 2018 Female and male life expectancies have converged in most industrialized societies in recent decades. To achieve coherent forecasts between females and males, this convergence needs to be considered when forecasting sex-specific mortality.

Sex ratios in the rodent malaria parasite, Plasmodium chabaudi [PDF]
, 2003 The sex ratios of malaria and related Apicomplexan parasites play a major role in transmission success. Here, we address 2 fundamental issues in the sex ratios of the rodent malaria parasite, Plasmodium chabaudi.

Uniform female-biased sex ratios in alpine willows [PDF]
, 2012 Premise of the study: The development of biased sex ratios in dioecious plant species has been ascribed to either (1) factors influencing differential adult mortality of male and female plants or (2) factors acting at an early life stage that determine ...

Mother's occupation and sex ratio at birth
BMC Public Health, 2010 Background Many women are working outside of the home, occupying a multitude of jobs with varying degrees of responsibilities and levels of psychological stress. We investigated whether different job types in women are associated with child sex at birth,

Girl or boy? Prenatal lead, cadmium and mercury exposure and the secondary sex ratio in the ALSPAC study [PDF]
, 2014 The aim of this study was to evaluate the effect of prenatal exposure to lead, cadmium and mercury levels on the secondary sex ratio. Whole blood samples were collected from pregnant women enrolled in the Avon Longitudinal Study of Parents and Children ...
