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 …

Although sex is a fundamental component of eukaryotic reproduction, the genetic systems
that control sex determination are highly variable. In many organisms the presence of sex …

A central goal of evolutionary biology is to identify the genes and evolutionary forces that
cause speciation, the emergence of reproductive isolation between populations. Despite the …

What are the causes of natural selection? Over 40 years ago, Van Valen proposed the Red
Queen hypothesis, which emphasized the primacy of biotic conflict over abiotic forces in …

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 …

The three fruitfly species of the Drosophila simulans clade—D. simulans, D. mauritiana, and
D. sechellia—have served as important models in speciation genetics for over 40 years …

There are few patterns in evolution that are as rigidly held as Haldane's rule (HR), which
states,“When in the first generation between hybrids between 2 species, 1 sex is absent …

Sex chromosomes are havens for intragenomic conflicts. The absence of recombination
between sex chromosomes creates the opportunity for the evolution of segregation …

Meiotic drive causes the distortion of allelic segregation away from Mendelian expected
ratios, often also reducing fecundity and favouring the evolution of drive suppressors. If …

Sex chromosome meiotic drive, the non-Mendelian transmission of sex chromosomes, is the
expression of an intragenomic conflict that can have extreme evolutionary consequences …
