Chromosomal inversions are associated with local adaptation in many species. However,
questions regarding how they are formed, maintained and impact various other evolutionary …

Androgens are pleiotropic and play pivotal roles in the formation and variation of sexual
phenotypes. We show that differences in circulating androgens between the three male …

In a balanced lethal system, half of the reproductive output always succumbs. A clear
example is observed in Triturus newts, which contain two distinct versions of chromosome 1 …

The ruff sandpiper (Calidris pugnax) is a lekking shorebird with three male morphs that differ
remarkably in behavior, ornaments, size, and endocrinology. The morphs are determined by …

Genetic linkage maps are valuable resources for investigating chromosomal structure,
quantifying karyotype, estimating recombination rates, and improving preexisting genome …

Sex chromosomes and mating-type chromosomes can carry large regions with suppressed
recombination. As a result of a lower efficacy of selection, recessive deleterious mutations …

In the colorful world of avian courtship, the ruff (Calidris pugnax) is in a league of its own.
Breeding in marshes and wet meadows across Eurasia, the males of this medium-sized …

Evolutionary biology aims to explain the diversity seen in nature. Evolutionary theory
provides frameworks to understand how simple polymorphisms or continuous variation are …

Supergenes can evolve when recombination-suppressing mechanisms like inversions
promote co-inheritance of alleles at two or more polymorphic loci that affect a complex trait …

Recombination suppression often evolves around mating compatibility loci, generating
supergenes. Using hundreds of available genomes and generating high-quality genome …
