[HTML][HTML] Evolving inversions
Empirical data suggest that inversions in many species contain genes important for
intraspecific divergence and speciation, yet mechanisms of evolution remain unclear. While …

How chromosomal inversions reorient the evolutionary process
Inversions are structural mutations that reverse the sequence of a chromosome segment
and reduce the effective rate of recombination in the heterozygous state. They play a major …

Sheltering of deleterious mutations explains the stepwise extension of recombination suppression on sex chromosomes and other supergenes
Many organisms have sex chromosomes with large nonrecombining regions that have
expanded stepwise, generating “evolutionary strata” of differentiation. The reasons for this …

Genetic variation for adaptive traits is associated with polymorphic inversions in Littorina saxatilis
Chromosomal inversions have long been recognized for their role in local adaptation. By
suppressing recombination in heterozygous individuals, they can maintain coadapted gene …

Natural selection and the distribution of chromosomal inversion lengths
T Connallon, C Olito - Molecular Ecology, 2022 - Wiley Online Library
Chromosomal inversions contribute substantially to genome evolution, yet the processes
governing their evolutionary dynamics remain poorly understood. Theory suggests that a …

The adaptive significance of chromosomal inversion polymorphisms in Drosophila melanogaster
Chromosomal inversions, structural mutations that reverse a segment of a chromosome,
cause suppression of recombination in the heterozygous state. Several studies have shown …

The interplay of local adaptation and gene flow may lead to the formation of supergenes
Supergenes are genetic architectures resulting in the segregation of alternative
combinations of alleles underlying complex phenotypes. The co‐segregation of alleles at …

Recent evolution of a maternally acting sex-determining supergene in a fly with single-sex broods
Sex determination is a key developmental process, yet it is remarkably variable across the
tree of life. The dipteran family Sciaridae exhibits one of the most unusual sex determination …

Adding New Pieces to the Puzzle of Karyotype Evolution in Harttia (Siluriformes, Loricariidae): Investigation of Amazonian Species
Simple Summary Fishes represent a useful model for evolutionary studies, given their
diversity of species and habitats. In this study, we investigate the chromosomes of three …

Weak antagonistic fitness effects can maintain an inversion polymorphism
The study of chromosomal inversion polymorphisms has received much recent attention,
particularly in cases where inversions have drastic effects on phenotypes and fitness (eg …
