A founder population of interesting creatures is established, and the average probability of identity by descent is calculated for each subsequent generation as follows: Generation F 1 0.05 2 0.0975 3 0.142625 4 0.2283625 a) What are the effective population sizes Ne for each Generation 1 through 4, relative to Generation 0 (the founder population)? b) What is the effective population size of Generation 4 relative to Generation 3? c) Is there any evidence for changes in population size after the founder event, and if so, at which generation did the size change in the number of breeding individuals occur?
Figure 19.11 Age structure diagrams for rapidly growing, slow growing, and stable populations are shown in stages 1 through 3. What type of population change do you think stage 4 represents?
One concept of conservation biology is known as minimum viablepopulation. Some species’ populations are so fragmented andsmall that they may have very little genetic variability left. Withminimal genetic variation in the population, there is little likelihoodthat a population can adapt to an environmental threat, such as anew disease. Florida panthers are at or below the minimum viablepopulation level (estimated population less than 80). 1)Do you think that it is practical to use limited resources toconserve a population like the Florida panther? 2)Why?
Some demographers claim that the total world population has already begun to slow, while others dispute this claim. How would you recognize a true demographic transition as opposed in mere random fluctuations in birth and death rates?
Scenario 2In the year 2015, another group of scientists studied the squirrel coat color and found that the population of squirrels had increased. They found 850 squirrels in the same area, of which 115 had a red coat. Assume that the population is in Hardy Weinberg’s equilibrium. 5B. What is the frequency of the recessive allele?(Put your answer here rounded to the nearest hundredth)
first, identify which assumption of Hardy- Weinberg equilibrium is most affected, second indicate whether what is being described will act to establish or violate equilibrium, and third, explain whether that example will increase or decrease that population’s genetic variation (VG). Hint, think of VG as a bell curve that is altered in its shape by certain evolutionary mechanisms (violations of H-W assumptions). 1) After growing and maturing in the ocean, Coho salmon normally spawn in the freshwater stream where they were born. Occasionally an individual will erroneously spawn in a nearby river instead of in their natal waters. What assumption is being violated and what will these errors do to VG of the original coho population?
What is a cline? A. Discrete changes in genetic or phenotypic characteristics of a population over geographic space. B. Similar genetic or phenotypic characteristics of a population within the same geographic space. C. A gradual change in genetic or phenotypic characteristics of a population over geographic space. D. A gradual change in genetic or phenotypic characteristics of a population within a set geographic space.
if a population of jumping spiders consists of 40 females and 40 males, what is the effective population size? Give the appropriate equation and show your work. Will genetic drift be an important evolutionary force in this population? Why or why not? If your answer is "yes", what does genetic drift do to allele frequencies? If your answer is "no", name two forces other than genetic drift that might be important in determining allele frequencies. asap
In a 13-year study of population dynamics of the invasive Asian shore crab (Hemigrapsus sanguineus) in Long Island Sound, Kraemer (2019) found that density declined over time, and the largest size classes declined the most. At the same time, average size of breeding females also declined w). Based on your understanding of life-history strategies, develop a hypothesis that would explain this pattern. Explain the reasoning behind it in enough detail that another student would be able to understand it.
Which of the following are examples of density-dependent factors for populations? The populations in question are bolded A. The bubonic plague wiping out 1/3 of Europe's human population in the 14th century B. Earthworms (Lumbricus terrestris) emerging from the soil after a rainstorm and subsequently drying out/dying C. Hurricane Florence killing all the pigs on someone's farm D. Waste accumulating in your fish tank
