Web19 Apr 2024 · Isolating mechanisms are typically grouped into premating, postmating–prezygotic, and postzygotic factors that affect the mating, fertilization, and offspring (and backcross) fitness between individuals of these 2 populations when they have the opportunity to interbreed ( Coyne and Orr 2004, Price 2008 ). Web13 Jul 2024 · A rich theoretical literature suggests that the ability of intrinsic postzygotic barriers to prevent introgression depends on three aspects of barrier loci: (i) the genetic architecture, (ii) the genetic context, and (iii) the mechanism of evolution. We discuss each of these in turn.
