Evolution of Hybrid Inviability Associated With Chromosome Fusions

Molecular Ecology, EarlyView.
ABSTRACT Chromosomal rearrangements, such as inversions, have received considerable attention in the speciation literature due to their hampering effects on recombination. Less is known about how other rearrangements, such as chromosome fissions and fusions, can affect the evolution of reproductive isolation. Here, we use crosses between populations of

The Distribution and Dispersal of Large Haploblocks in a Superspecies

Molecular Ecology, EarlyView.
ABSTRACT Haploblocks are regions of the genome that coalesce to an ancestor as a single unit. Differentiated haplotypes in these regions can result from the accumulation of mutational differences in low‐recombination chromosomal regions, especially when selective sweeps occur within geographically structured populations.

3D Genome Constrains Breakpoints of Inversions That Can Act as Barriers to Gene Flow in the Stickleback

Molecular Ecology, EarlyView.
ABSTRACT DNA within the nucleus is organised into a well‐regulated three‐dimensional (3D) structure. However, how such 3D genome structures influence speciation processes remains largely elusive. Recent studies have shown that 3D genome structures influence mutation rates, including the occurrence of chromosomal rearrangement.

Genome Architecture and Speciation in Plants and Animals

Molecular Ecology, EarlyView.
ABSTRACT There have been numerous treatments of specific topics in speciation, but surprisingly few papers have compared patterns and processes of speciation across different organismal groups. In this review, we partially address this gap by asking how variation in genome architecture impacts speciation across the plant and animal kingdoms.
