Karyotypes are generally conserved between closely related species and large chromosome rearrangements typically have negative fitness consequences in …
In many multicellular eukaryotes, heteromorphic sex chromosomes are responsible for determining the sexual characteristics and reproductive functions of individuals. Sex …
Females and males often have markedly different mortality rates and life spans, but it is unclear why these forms of sexual dimorphism evolve. The unguarded X hypothesis …
Changes in chromosome numbers, including polyploidy and dysploidy events, play a key role in eukaryote evolution as they could expediate reproductive isolation and have the …

Abstract Grasshoppers (Orthoptera: Acrididae) are known for their significantly enlarged genome compared to other insects. However, our understanding of the evolutionary …
Chromosomal mutations such as fusions and fissions are often thought to be deleterious, especially in heterozygotes (underdominant), and consequently are unlikely to become …
