NTRODUCTION Under nearly all circumstances, postzygotic reproductive isolation cannot evolve under the direct action of natural selection. Instead, postzygotic isolation evolves as a by-product of other genetic changes as proto-species diverge. In contrast, natural selection can directly act to enhance prezygotic reproductive isolation. Consider two species with overlapping ranges. If hybrids between the species are less fit than pure species individuals, females that mated with heterospecific males would be at a selective disadvantage, because their resulting offspring had low fitness....
need help with this .. From the pages 571-587 attached below. 1a) Suppose a population of guppies was infected with a parasite. In that population a mutation results in a parasite resistant genotype that spreads through the population through natural selection. A subsequent mutation in the parasite results in a genotype that is unaffected by the newly evolved resistant guppy genotype. What is the name of the hypothesis that explains this host parasite “arms race”.? 1b) What is this name...
