Meiotic drivers are genetic variants that selfishly manipulate the production of gametes to
increase their own rate of transmission, often to the detriment of the rest of the genome and …

All plant and animal species arise by speciation—the evolutionary splitting of one species
into two reproductively incompatible species. But until recently our understanding of the …

Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis
and the fusion of two gametes of different sexes or mating types. Sex-determination …

Many species groups, including mammals and many insects, determine sex using
heteromorphic sex chromosomes. Diptera flies, which include the model Drosophila …

Sex chromosomes have evolved many times in animals and studying these replicate
evolutionary “experiments” can help broaden our understanding of the general forces …

Understanding the processes of population divergence and speciation remains a core
question in evolutionary biology. For nearly a hundred years evolutionary geneticists have …

Population genetics theory predicts that X (or Z) chromosomes could play disproportionate
roles in speciation and evolutionary divergence, and recent genome-wide analyses have …

Meiotic drivers are a class of selfish genetic elements whose existence is frequently hidden
due to concomitant suppressor systems. Accordingly, we know little of their evolutionary …

Sex chromosomes are susceptible to the evolution of selfish meiotic drive elements that bias
transmission and distort progeny sex ratios. Conflict between such sex-ratio drivers and the …

Hybrid incompatibility (including sterility, lethality, and less extreme negative effects)
interests evolutionary biologists because of its role in speciation as a reproductive isolating …
