WHAT IF? Consider two species that diverged whilegeographically separated but resumed contact beforereproductive isolation was complete. Predict the outcome over time if the two species mated indiscriminately and (a) hybrid offspring survived and reproducedmore poorly than offspring from intraspecific matingsor (b) hybrid offspring survived and reproduced as wellas offspring from intraspecific matings.
WHAT IF? Suppose that two species, A and B, havesimilar appearances but very divergent gene sequences,while species B and C have very different appearancesbut similar gene sequences. Which pair of species is morelikely to be closely related: A and B or B and C? Explain.

What are the differences among the three possible outcomes for hybrids over time: reinforcement, fusion, and stability?arrow_forwardMAKE CONNECTIONS Explain how natural selection could increase the resemblance of a harmlessspecies to a distantly related harmful species. In addition to selection, what else could account for a harmlessspecies resembling a closely related harmful species? (See Concept 22.2.)arrow_forwardHow come dispersal is still allopatric speciation? I was under the impression that a new geographical barrier would have to develop and separate a once-uniform species.

- . WHAT IF? Do speciation rates in closely related cladesof flowering plants show that flower shape is correlatedwith the rate at which new species form or that flowershape is responsible for this rate? Explain.arrow_forwardTry to outline a scenario explaining the evolution of the three species shown in panel g. Use migration, mutation, genetic drift, selection, reproductive isolation, gene flow, extinction, and many generations in your scenario. Based on your scenario, what are the components that are necessary in a population in order for it to split or diverge into two new daughter species from a single ancestor (the parent species)?arrow_forwardIs allopatric speciation more likely to occur on an island close to the mainland or on a more isolated island of the same size?

- WHAT IF? Suppose gene A is orthologous in species 1and species 2, and gene B is paralogous to gene A inspecies 1. Suggest a sequence of two evolutionary eventsthat could result in the following: Gene A differs considerably between species, yet gene A and gene B show littledivergence from each other.arrow_forward13) Lake Malawi in Africa is home to about 200 species of allopatrically speciated cichlid fish. However, recent development around the lake is reducing the visabiliy in the lake, and as a result recently diverged species are merging back together. Why? A) Because the geneflow between species has been reduced due to the reduction in visability B) Because those species have not evolved a second reproductive isolation mechanism in addition to sexual selection C) Because the open water habitat is no longer as habitable, so the open water species are now using the bottom habitat D) Because the bottom habitat is no longer habitable, so the bottom habitat species are not using the open water habitat, leading to more hybridizationarrow_forwardSome females seem to prefer the blue color and some females seem to prefer yellow color. If this a diversifying/ disruptive selection, how could diversifying/disruptive selection result in sympatric speciation in this example?arrow_forward
