Which of the following scenarios would result in a different species designation for two populations under the phyiogenetic and biological species concepts Select one O a, there is no gene flow, all hybrids are sterile O b each population forms a monophyletic group; populations mate during different seasons O c. there is no gene flow, fertile hybrids are produced when bred in the lab O d each population is paraphyletic, fertile hybrids are produced when bred in the lab
Under the biological species concept, which of the following statements is/are true? a) Gene flow can occur between species. b) Species are independent evolutionary lineages. c) Isolating mechanisms prevent gene flow between species. d) Geographic isolation and differences in the timing of mating are two mechanisms that allow populations to genetically diverge. e) Donkeys and horses are not species.
Which of the following is a weakness of the biological species concept? Group of answer choices Experts can disagree about whether populations are similar enough to be the same species. It isn’t applicable to asexual, fossil, or geographically isolated species It requires phylogenetic trees, which haven’t been estimated yet for many lineages. It was the first rigorous species concept published.
Question 13 1 pts In a hypothetical scenario, imagine that you have discovered a rare species of bird on a remote Pacific island. You spend some time studying their ecology and habitation and discover that although these birds look alike, they are indeed two distinct populations with very different mating calls. You propose that these two populations must be two species since they are no longer able to mate with one another. Which of the following species concepts would you...
For the following A-C choose the best answer: A) A new species of fruit-eating bat enters a community. In order for the new bat species to coexist the other species of fruit-eating bat, both species specialize on eating different types of fruit even though other fruits can be eaten by them. In this example of niche differentiation, the niche breadth of both species _______, and the type of niche that changed was their _____. Group of answer choices increased; fundamental...
7. Classifying extinct species is difficult, and usually must integrate data from fossil measurements, inferences on ecology (e.g. classifying carnivore, herbivore using teeth, etc.), and how these are likely to change or not over deep timescales. Which of the following species concepts is likely most usable and operational for extinct taxa, like the dinosaurs in the above tree? Phenetic species concept Evolutionary species concept Biological species concept Fossil species concept None of the above 8. Theropoda (theropods) contains many of...
Which of the following are concepts or terms relevant to the discipline of disaster recovery? [Choose all that apply.]
24. Which of the following species concepts is defined by populations of interbreeding individuals that are reproductively isolated from other populations? A. phylogenetic B. ecological C. biological D. morphologicalOn the Bahamian Island of Andros, mosquitofish populations live in now-isolated, freshwater ponds that were once united. Currently, some predator-rich ponds have mosquitofish with a body shape that allows them to swim in short, fast bursts. Other predator-poor ponds have mosquitofish with a body shape that allows them to swim continuously for a...
which of the following statements describes biological diversity? A. variety of species within different ecosystems B. The number of species in an area C. Variation within the genes of a species D. variety of ecosystems found in an area.
Which of the following choices accurately describe what makes one person different from another with regard to traits (such as height) that have a very high heritability? Choose all that apply Group of answer choices Random factors during development is the most significant causes of differences between people None of the other choices are accurate What makes us different is not that we have different genes, but that we have different alleles of many of those genes What makes us...
