Evolutionary divergence between homologous X–Y chromosome genes shapes sex-biased biology
Sex chromosomes are a fundamental aspect of sex-biased biology, but the extent to which homologous X–Y gene pairs (‘the gametologs’) contribu…

Detecting adaptive changes in gene copy number distribution accompanying the human out-of-Africa expansion
Genes with multiple copies are likely to be maintained by stabilizing selection, which puts a bound to unlimited expansion of copy number. We desig…
Transitions in sex determination mechanisms through parental and sexual antagonism
Sex chromosomes carry the sex-determining locus, causing them to be differently transmitted to and from females and males. These differences lead t…
Accelerated differentiation of neo-W nuclear-encoded mitochondrial genes between two climate-associated bird lineages signals potential co-evolution with mitogenomes
There is considerable evidence for mitochondrial-nuclear co-adaptation as a key evolutionary driver. Hypotheses regarding the roles of sex-linkage …
Support for Y-compensation of mother’s curse affecting lifespan in Drosophila melanogaster
Mother’s curse refers to male-biased deleterious mutations that may accumulate on mitochondria due to its strict maternal inheritance. If these m…
Desert landscape features influencing the microgeographic genetic structure of Nelson’s pocket mouse Chaetodipus nelsoni
Elucidating the factors that drive the genetic patterns of natural populations is key in evolutionary biology, ecology and conservation. Hence, it …
Convergent evolution of complex adaptive traits modulates angiogenesis in high-altitude Andean and Himalayan human populations
Convergent adaptations represent paradigmatic examples of the capacity of natural selection to influence organisms’ biology. However, the possibi…
