A dual level model for speciation by multiple pericentric inversions

Abstract: A considerable body of evidence suggests that the deleterious meiotic effects of pericentric inversions in F1 hybrids can be overcome by changes in chiasma location and various means of nonhomologous pairing. Such overriding mechanisms may render pericentric inversions benign and increase the likelihood of their fixation in population isolates. It has been argued that overriding mechanisms of this type negate the involvement of pericentric inversions as reproductive isolating mechanisms in speciation. It is su… Show more

“…In most animal and plant groups there are differences regarding the chromosomal number among closely related species (King 1993). Nonetheless, not all of the changes that may operate on the chromosomes are implicated in speciation phenomena (King 1987), but only those that have potential to diminish the biological efficiency of the hybrids, which are known as negative heterotic (Forsdyke 2004;King 1987King , 1992Rieseberg 2001), or that even impede their viability. Both cases, at shorter or longer term, give rise to reproductive isolation among populations and therefore, are likely to cause speciation (White 1978).…”

“…Multiple pericentric inversions are an important mechanism of post-zygotic isolation (King, 1992). Events of this magnitude could favor speciation in extremely territorial coral species such as Stegastes.…”
