Chromosomal inversions have long fascinated evolutionary biologists due to their
suppression of recombination, which can protect co-adapted alleles. Emerging research …

As populations diverge, genetic differences accumulate across the genome. Spurred by
rapid developments in sequencing technology, genome-wide population surveys of natural …

The rediscovery of Mendel's work showing that the heredity of phenotypes is controlled by
discrete genes was followed by the reconciliation of Mendelian genetics with evolution by …

Many organisms have sex chromosomes with large nonrecombining regions that have
expanded stepwise, generating “evolutionary strata” of differentiation. The reasons for this …

Gene flow is a fundamental evolutionary force in adaptation that is especially important to
understand as humans are rapidly changing both the natural environment and natural levels …

The ruff is a Palearctic wader with a spectacular lekking behavior where highly ornamented
males compete for females,,,. This bird has one of the most remarkable mating systems in …

Studies in diverse biological systems have indicated that host–parasite co-evolution is
responsible for the extraordinary genetic diversity seen in some genomic regions, such as …

Bottlenecks in population size can reduce fitness and evolutionary potential, yet introduced
species often become invasive. This poses a dilemma referred to as the genetic paradox of …

A major challenge in biology is to understand the genetic basis of adaptation. One
compelling idea is that groups of tightly linked genes (ie," supergenes"[1, 2]) facilitate …

Supergenes are sets of genes that are inherited as a single marker and encode complex
phenotypes through their joint action. They are identified in an increasing number of …
