Incompatibilities in interspecific hybrids, such as sterility and lethality, are widely observed
causes of reproductive isolation and thus contribute to speciation. Because hybrid …

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 …

Postzygotic reproductive isolation in response to interploidy hybridizations is a well-known
phenomenon in plants that forms a major path for sympatric speciation. A main determinant …

Mass releases of sterilized male insects, in the frame of sterile insect technique programs,
have helped suppress insect pest populations since the 1950s. In the major horticultural …

Hybrid incompatibilities (HIs) cause reproductive isolation between species and thus
contribute to speciation. Several HI genes encode adaptively evolving proteins that localize …

Heterochromatin protein 1 (HP1a) has conserved roles in gene silencing and
heterochromatin and is also implicated in transcription, DNA replication, and repair. Here we …

Hybrid sterility (HS) belongs to reproductive isolation barriers that safeguard the integrity of
species in statu nascendi. Although hybrid sterility occurs almost universally among animal …

Speciation involves the reproductive isolation of natural populations due to the sterility or
lethality of their hybrids. However, the molecular basis of hybrid lethality and the …

Proteins are the workhorses of the cell and execute many of their functions by interacting
with other proteins forming protein complexes. Multi-protein complexes are an admixture of …

The Dobzhansky and Muller (DM) model explains the evolution of hybrid incompatibility (HI)
through the interaction between lineage-specific derived alleles at two or more loci. In …
