- Tiny foxes live on the Channel Islands off the coastof Southern California; the adults weigh less than3 lbs. These so-called island foxes (Urocyon littoralis) derived from the mainland gray fox (Urocyoncinereoargenteus). Analysis of genome sequencesrevealed that unlike the mainland foxes, the foxeson a single island have shockingly little geneticdiversity.a. The genome of only one fox from each island wassequenced. How would the lack of genetic diversitybe evident in a single genome sequence?b. The populations of the foxes on each island aresmall. How might the low diversity have occurred?c. Why is low genetic diversity thought to lead tospecies extinction?d. Hypothesize as to why the Channel Island foxesare thriving without human assistance despite theirlack of genome sequence diversityIn the western United States, populations of an annual plant can be found almost continuously from San Diego to Seattle. Even though individuals from the San Diego and Seattle populations never come into contact, they can still be considered part of the same species under the ________ species concept because they can potentially interbreed. A.biologicalB.morphologicalC.lineageD.habitatDescribe the types of mutation discussed in class and the consequences these haveforthe evolution of populations. What types of mutations are most common in naturalpopulations? Provide examples and data.
- The difference between sympatric and parapatric speciation is ___. a. parapatric speciation occurs only in worms b. sympatric speciation requires a barrier to gene flow c. the extent of overlap in range d. reproductive isolation does not occurConsider two species that diverged whilegeographically separated but resumed contactbefore reproduction isolation was complete. Predictwhat would happen over time if two species matedindiscriminately and a. hybrid offspring survived and reproducedmore poorly than offspring from intraspecificmating or b. hybrid offspring survived and reproduced aswell as offspring from intraspecific mating.Provide an example for each to illustrate yourpoint.A. What kind of speciation do we normally associate with members from one population being geographically displaced to a new, smaller population? Geospiza scandens B. What kind of speciation do we normally associate with members of a population that become ecologically, genetically or behaviorally distinct within that population such that they become reproductively isolated?
- Which of the following factors would not contribute toallopatric speciation?(A) The separated population is small, and genetic drift occurs.(B) The isolated population is exposed to different selectionpressures than the ancestral population.(C) Different mutations begin to distinguish the gene pools ofthe separated populations.(D) Gene flow between the two populations is extensive.Do all the phylogenetictrees below represent thesame relationships (sametopology)? If not, circle thetree(s) that is/are differentand explain why in the spaceto the left.Allopatric, but not sympatric, speciation requiresa. reproductive isolation.b. geographic isolation.c. spontaneous differences in males and females.d. prior hybridization.e. rapid rate of mutation.
- In what way can the frequency of a genotype change over time when genetic drift is theonly agent affecting its evolution? Refer to your Figure 2 at update 500 (i.e. the flrxgenotype histogram)When artificial selection is practiced over many generations, it iscommon for the trait to reach a plateau in which further selectionhas little effect on the outcome of the trait. This phenomenon isillustrated as shown. Explain why it occurs.Which traits are symplesiomorphic (i.e. plesiomorphic for all ingroup species) on your tree?
