- Which of the following forms of reproductive isolation illustrates a prezygotic barrier to gene flow? O Species A forms hybrids with species B and the hybrids are able to breed back with either of the two parent species to produce healthy fertile offspring. O Two closely related birds, the lazuli bunting and indigo bunting, sing similar songs to attract mates and even though human ears can not distinguish them the females never make wrong choices in choosing who to mate with. O Two species of turtles living in a large lake have different ecological requirements and never interact. O Several species of corrals in a Honduras corral reef release gametes about the same time but inter- specific attraction of gametes does not occur. O All but one of these illustrates a type of prezygotic barrier to gene flow.many places, there are lots of squirrels in Arizona. Over millions of years the Grand Canyon formed. Now, the squirrels on the north and south rims of the canyon cannot reach each other and Like therefore no longer interbreed. 1) If a squirrel from the north rim and a squirrel from the south rim were put in the same room, would they breed? Why or why not? 2) Is this an example of allopatric or sympatric speciation? How do know? youA. 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?
- Hybridization was not originally recognized as a mechanism of speciation by either Darwin or the researchers of the "new synthesis". However, today there are many examples of species that have originated through hybridization. What is the best explanation for why we have so many examples of species originating through hybridization? Hybridization is more likely to occur in regions where scientists have put in more effort studying speciation Hybridization has been carried out frequently by farmers attempting to produce new, better species to grow Hybridization occurs fairly regularly, and when it leads to new species only takes a few generations, which is fast enough for researchers to see fairly easily Hybridization is fairly easy to study in captivityThere is a fish species that lives in a lake. As the fish population grows, competition for food increases and a group of fish locates a new food source at a different depth in the lake. Over time, two populations with distinct morphologies that allow them to eat various food sources begins to occur in the lake. Which type of speciation (allopatric or sympatric) will mostly likely occur? Why?a) How many of the gene trees do you expect to look like the species tree? b) You observe three gene trees in which species X and Z are the closest relatives and seven gene trees where X and Y are the closest relatives. What can you conclude from these data? Group of answer choices Historical hybridization between species W and X Historical hybridization between species X and Y Historical hybridization between species X and Z Historical hybridization between species Y and Z
- What role does geographic isolation play in the formation of a new species? Group of answer choices A.If two populations become isolated geographically, then the two populations cannot interbreed with one another. There will be gene flow between the two. This will allow the two isolated populations to evolve independently leading to new species. B. If two populations become isolated geographically, then the two populations can interbreed with one another. There will be no gene flow between the two. This will allow the two isolated populations to evolve independently leading to new species. C. None of the answers are correct D. If two populations become isolated geographically, then the two populations cannot interbreed with one another. There will be no gene flow between the two. This will allow the two isolated populations to evolve independently leading to new species.Two populations of wildflower are found in the same meadow, and genetic analysis indicates that they descended from a common ancestor that arrived to the meadow several hundred years ago. However, one population only produces flowers and pollen in the early summer, the other only produces flowers and pollen in the fall. Is this an example of: a. Sympatric speciation maintained by prezygotic RIM x Allopatric speciation maintained by postzygotic RIM Allopatric speciation maintained by prezygotic RIM d. Sympatric speciation maintained by postzygotic RIM bWhat are examples for gene flow? Select all that apply A distinct population of iguana drift to a new island that is already inhabited by members of the same species. A small population of humans colonizes a newly formed island. A fire drastically reduces the size of a white-tailed deer population. The remaining individuals spread out throughout the remaining forest. Wind blows pollen from one population of plants to another and cross-fertilization occurs. n An earthquake results in the formation of a canyon, splitting a population of toads apart.
- Within a population of sunflowers, a new individual has a novel dominant mutation that causes it to flower 4 months earlier than the rest of the population. That sunflower survives and successfully self-fertilizes, leading over time to a novel population that evolves larger leaves and smaller flowers. This new population does not interbreed with the original population, although they are found in the same areas. This is an example of Allopolyploid speciation O Behavioral isolation O Allopatric speciation O Sympatric speciation O Adaptive radiationThe biological species concept depends on the existence of barriers to reproduction. What are they? Does this species concept apply in all situations? Think of an example from nature where the biological species concept would NOT be that applicable. Which species concept would be better in this example? How does speciation occur? What environmental factors might contribute to speciation? Can an individual speciate? Use terminology for the two kinds of speciation we have learned about. What is “gene flow”? What does it mean if there is NO gene flow? Two groups of individuals are separated by either side of a canyon. One researcher found that they do not cross the canyon at any point. The group on the north side have fluffy tails and thicker coats, and they do not eat moss. The south side individuals eat moss almost exclusively, have a thin coat and tail, but otherwise are generally identical. When in the lab they mated successfully, and the offspring of that mating also mated…Some 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?
