Hybridization has many and varied impacts on the process of speciation. Hybridization may
slow or reverse differentiation by allowing gene flow and recombination. It may accelerate …

Understanding the genetic architecture of speciation is a major goal in evolutionary biology.
Hybrid dysfunction is thought to arise most commonly through negative interactions between …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

Hybrid breakdown, or outbreeding depression, is the loss of fitness observed in crosses
between genetically divergent populations. The role of maternally inherited mitochondrial …

Much progress has been made in the past two decades in understanding Darwin's mystery
of the origins of species. Applying genomic techniques to the analysis of laboratory crosses …

Hybrid incompatibility (including sterility, lethality, and less extreme negative effects)
interests evolutionary biologists because of its role in speciation as a reproductive isolating …

Ecological speciation is the process by which barriers to gene flow between populations
evolve due to adaptive divergence via natural selection. A relatively unexplored area in …

Discrepancies between morphology-based taxonomy and phylogenetic systematics are
common in Scleractinian corals. In Pocillopora corals, nine recently identified genetic …

Genetic incompatibilities are an important component of reproductive isolation. Although
theoretical studies have addressed their evolution, little is known about their maintenance …

Abstract Schizophrenia's (SZ's) heritability and familial transmission have been known for
several decades; however, despite the clear evidence for a genetic component, it has been …
