Slect true or false for each The stickleback is a fish native to many coastal waters throughout North America, including Oregon.It shows many phenotypic variations, making it ideal for studies in evolution and population genetics(including here at UO). Suppose that a single population of stickleback lives in a local pond. Droughtcauses much of the pond to dry up, leaving behind two smaller ponds (Pond 1 & Pond 2). 500 of thesticklebacks are in Pond 1 and 50 of the sticklebacks are in Pond 2.Below is a simulation of how the frequency of a particular allele might change over 500 generationsin the fragmented stickleback population. The lines are labeled: pond 1 and pond 2 and the initialallele frequency was set to 0.5.pond 2Population Genetics Simulation pond 120406080100120140160180 200 220240 260280300320340360380440460480GenerationSimulation Parameters Open All Show HelpGraph successfully areated on Sun Apr 12 2020 204454 GMT0700 (Pacific Daylight Time)W Generate Graph+Add LineGraph1(Hide Legend)Generations: t 500Population SizeN= 00Starting Allele Frequency: p 0.5W Graph2(Hide Legend)Generations: t 00Population Size: N = s0Starting Allele Freuency: p= 0.5Given that genetic drift is the only evolutionary force acting on these populations, which of thefollowing is true?

The Tibetans and Han Chinese share several genetic traits and DNA. However the EPAS1 gene which increases the ability of red blood cells carry oxygen even in low environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is commonly in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in 3-5 sentences
A population of 600 scorpions was split into four populations when irrigation canals were built through their habitat. The four new populations were called the Northern, Southern, Eastern, and Western populations. Each new population consisted of about 150 individuals. The four populations continued to evolve, and no migration occurred among populations. One hundred generations later, each population still has about 150 individuals, and a biologist investigates them. Consider what a biologist expect to see in the four populations after 100 generations if the environment did not change for any of the populations. Would the biologist agree or disagree with the following statements? a) In the smaller populations of 150 individuals, the processes leading to genetic drift could have a stronger influence on a gene than natural selection. agree or disagree b)Chance survival of some individuals occurred in some generations, but not every generation. agree or disagee c)Beneficial mutations…
New Zealand snapper populations were found to be under the influence of genetic drift, suggesting overfishing was still an issue for them, despite the New Zealand fisheries estimating their total population size to be over 3 million. Which of the following is the best explanation for this observation? A) Pelagic fish, like the New Zealand snapper, often only have a few reproductive individuals, therefore their effective population size is actually much smaller than the total population size. B) Pelagic fish, like the New Zealand snapper, often have an equal sex ratio which affects the number of breeding individuals. C) Pelagic fish, like the New Zealand snapper, often have disassortative mating which affects the number of breeding individuals. D) Pelagic fish, like the New Zealand snapper, often have assortative mating which affects the number of breeding individuals.
A preserve contains the last population of the very rare desert pupfish which is only found in one pool. There are two color forms of this pupfish, one is silver and one is black and the color is inherited. The color forms are equally successful in surviving and having offspring over the long term but the frequency of the two forms varies greatly from generation to generation. Which evolutionary force is causing the fluctuation in frequency?

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?
You are asked to assess whether a population of endangered salamanders can adapt to warming climate in their preferred habitat. The salamanders vary at a locus that determines adaptation to temperature, and the warming climate creates selection favoring one of two alleles at that locus. Drawing on what you know about natural selection and genetic drift, what information would you need to know about the salamanders to determine whether the allele that improves their adaptation to warmer climates will become fixed in the population? Strictly no plagiarism.
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?
Which of these conditions should completely prevent the occurrence of natural selection in a population over time? Group of answer choices The population size is large All variation between individuals is due only to environmental factors The population lives in a habitat where there are no competing species present The environment is changing at a relatively slow rate
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.
In a population of mayflies, variation in the STRIPE gene causes different body coloration. SS individuals have skinny stripes, Ss individuals have wide stripes, and ss individuals are unassigned. You collect some mayflies and estimate that the frequency of the S allele is 0.85. You want to know whether the population is evolving, so you will return to the same site next summer and collect 1000 mayflies from the next generation. If the population is not evolving, how many of the 1000 mayflies collected next summer should have wide stripes. (round to the nearest whole number) A. 255 b.850 C. 723 D. 23
A population of 1,000 wild turkeys is studied and observed by scientists on an island. The scientists construct a study over five years to observe the temperature, amount of precipitation, daily value of berries individually consumed that were their exclusive food source, and available habitat for nesting. The scientist determined that as the climate changed, the population began to decrease. Using the Hardy-Weinberg Equilibrium as a null hypothesis, which of the following observations made by the scientists would support an associated alternative hypothesis? Due to the climate change, some birds may emigrate to a cooler location that would lead to a variation in the gene frequencies within the population. Variations in gene frequency due to advantages in natural selection would cause a greater number of males in the population to have more desirable traits. An increase in food consumption would cause the population to begin to exceed the carrying capacity that leads to a…
