Genes described by this model must reduce a hybrid’s fitness, have functionally diverged, and depend on each other for incompatibility. For 10 points each:
[10h] Name this model of genetic incompatibility which posits that reproductive isolation occurs due to incompatibility of alleles at different loci.
ANSWER: Bateson-Dobzhansky-Muller model
[10e] Reproductive isolation is considered the defining characteristic of this evolutionary process that produces populations of organisms that cannot interbreed.
ANSWER: speciation
[10m] This mode of speciation occurs when populations become geographically isolated, preventing gene flow.
ANSWER: allopatric speciation
