Figure 4. — Rapid predator evolution can result in predator extinction in genetically asymmetric coevolution (coevolution between a prey's Mendelian trait and a predator's quantitative trait) [94]. Predation is more successful when traits match (i.e. a bidirectional axis of vulnerability [108]) due to, for example, handedness of snails and snakes. (a,c) Persistent predator–prey population cycles (a) and trait coevolution (c) when the additive genetic variance of the quantitative trait, v = 0.01. (b,d) Predator extinction (b) due to large amplitudes in trait coevolution (d) when additive genetic variance of the quantitative trait, v = 0.03. Black solid lines and grey dotted lines represent predator and prey species, respectively.
