However, when populations ofthe two species share a common geographic area, there are significant differences in theappearance of the two species. What conclusions might you draw from this situation?> View Available Hint(s)This is a case where hybrid offspring of the two species are less fit than either ofthe parent species. In the geographic areas where the populations overlap,natural selection has reinforced color differences that serve as reproductivebarriers between the two species.Hybrid offspring of the two species are more fit than either of the parent species.Eventually the two hybridizing species will fuse into one.O This is a case of random variation within the population.Even though the colors of the males of the two species are very similar in thegeographically isolated populations, you would expect that when researchersperformed mate-choice experiments, females would never chose males from thewrong species.

Distinct species that are able to interbreed in nature are said to “hybridize,” and their offspring are called “hybrids.” The gray oak and the Gambel oak can mate to produce fertile hybrids in regions where they co-occur. However, the gene ﬂow in nature is sufﬁciently limited that, overall, the two species remain phenotypically distinct. If the hybrid offspring survive well and reproduce to the extent that there is a large population of hybrid individuals that breed between themselves but do not interbreed with either of the two original parent species (the gray and the Gambel), which of the following would you say most likely led to the new hybrid species?(a) prezygotic reproductive barriers (b) sympatric speciation (c) allopatric speciation (d) postzygotic reproductive barriers (e) none of the above
Imagine that you are a conservation biologist responsible for the well-being of a bufello herd consistingof 100 mature males and 100 mature females. In this herd, there is no appreciable mutation, there isno migration in or out, and there is no selection. At the Fuzzy gene locus, there are two alleles, G and E.Homozygous G individuals have fuzzy fur, homozygous E individuals have rough fur, and heterozygoteshave shaggy fur. Suppose you survey the herd and find that there are 44 fuzzy individuals, 72 shaggyindividuals, and 84 rough individuals. Suppose you watch the buffalo and discover that while all the females breed, a small number of males(10) establish breeding harems, while the other males do not breed.a) What is the effective population size of this herd? That is, what size "ideal" population ofbalanced sex ratio would have genetics similar to this population?b)How does the effective population size compare to the actual population size?c) Under Hardy-Weinberg equilibrium, what…

4. Bird guides once listed the myrtle warbler and Audubon’swarbler as distinct species. Recently, these birds have beenclassified as eastern and western forms of a single species,the yellow-rumped warbler. Which of the following piecesof evidence, if true, would be cause for this reclassification?(A) The two forms interbreed often in nature, and theiroffspring survive and reproduce well.(B) The two forms live in similar habitats and have similar foodrequirements.(C) The two forms have many genes in common.(D) The two forms are very similar in appearance.
Try 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)?
ACTIVITY 9.2: Essay. Directions: Read the situation and identify the points of Darwin’s natural selection. There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time. Each spring when the worms reproduce, they have about 500 babies but only 100 of tthese 500 ever become old enough to reproduce.A. Describe variations in populations. ____________________________________________B. Describe how offspring inherit surviving parent’s traits. __________________________________________________________________________________________________________C.

Need help It has been found that rats with the genotype Ww are more resistant to Warfarin than either WW that have a VitK deficiency or ww that are very susceptible. Given that the relative fitness values are 1 for Ww, 0.37 for WW and 0.19 for ww, predict the allele and genotype frequencies once Hardy Weinberg equilibrium is established for a rat population in a grain elevator where warfarin is used continually. Suggest what might happen if warfarin use was stopped.
1. Explain how all 4 of the evolutionary aspects (mutation, gene flow,selection, and genetic drift) affect/have affected dogs for better or worse in present time ( or past time if relevant). Provide specific examples. 2. Explain how all 4 of the ecological interaction (mutualism, competition, predation, parasitism) affect/have affected dogs. Provide specifiv examples. Thank you
n the savannahs of the Amazon different species of the genus Ipomoea are pollinated by either bumblebees or hummingbirds; lavender flowered I. marabaensis and red flowered I. cavalcantei. Which of the follwing data would support the suggestion of natural interspecific hybridization with weak postzygotic isolation? A. magenta flowered hybrids found in the wild were infertile and bidirectionally crossing with parental species B. magenta flowered hybrids found in the wild were preferentially pollinated by introduced honeybees rather than parental pollinators C. In the laboratory, offspring resulting from crosses between I. cavalcantei, I. marabaensis showed a mixture of parental floral characteristics D. In the laboratory, offspring resulting from crosses between I. cavalcantei, I. marabaensis and magenta flowered hybrid plants were autotropic and showed hybrid viability
