Which of the following does not support Hoekstra's hypothesis for the evolution of coat color in oldfield mice? Blending into the background reduced predation rate in both beach and mainland habitats. Predation rates of dark clay models in beach habitats were higher relative to white models. Predation rates of 1ight models in mainland habitats were higher relative to dark models. Camouflage increased predation rate in both beach and mainland habitats.

Lithobates clamitus. also know as the green frog and bronze frog can range in in skin color from pure to brown to pure green and a mixture of both. As their habitats change frogs with a mixture of both colors have a higher fitness as they are better able to hide from predators. 1. If the change in the distribution of this trait is the result of natural selection, name the mode of selection (ie: Balancing, Disruptive, etc...) 2. If a small group of male frogs end up joining this population from a different population of frogs, which process of selection describes the movement of alleles present in the male frog? 3. The process you named in “c” ________ the genetic variation in the population that the male frog joined? (increase, decrease, or stay the same?)
The rough-skinned newt, which lives in western North America, stores a poison in its skin and is avoided by predators. However, several populations of garter snakes have undergone one or a few mutations that enablethem to tolerate the toxin, and these snakes eat the newts with no ill effects. How has natural selection affected this predator–prey relationship? Based on what you have learned about evolutionary arms races, predict what may happen to the newts and the poison-resistant garter snakes over time.
Darwin’s finches have different beaks in terms of size and shape to be able to eat different food sources like insects, nectar, and seeds. Cactus finches have longer, more pointed beaks to probe cactus flowers compared to their relatives, the ground finches. If a plant disease killed a large portion of the cacti on the Galapagos islands, what would the future populations of finches look like in terms of beak size and shape? Use your knowledge of natural selection to determine which option is most likely. Ground finches would survive and pass on their shorter and wider beaks, so there would be a higher proportion of finches in future generations that have short and wide beaks. Ground finches would survive and pass on their beaks, but they would mate with the remaining cactus finches, creating a new hybrid that is somewhere between short versus long and narrow versus wide. Cactus finches would compete for food with ground finches and exhibit resource partitioning, so the beaks…
The protruding tusk on a narwhal is an enlarged tooth with sensory capabilities. Narwhals are related to other whales. The extreme phenotype of the tusk demonstrates which type of selection? A)Convergent B)Stabilizing C)Directional
You are working on an undergraduate project, studying an insect species. A recent study showed that the pigmentation pattern used for camouflage is made by an enzyme K. However, it has been shown that, when compared to the Kk individuals, the KK homozygotes would have a higher chance of dying from pigment overdose before growing up, while the kk individuals can easily fall to predation before becoming adults. In fact, when compared to the Kk individuals, the estimated selection coefficients for KK and kk are 0.25 and 0.5, respectively. You are interested in what would happen to these alleles. At present, you have conducted a population survey and have 1000 larvae in your collection. Among them, 360 are KK, 480 Kkand 160 kk. 1)How many larvae would survive to adulthood a) 170 b) 414 c)583 d)750 e)830 2)Following up the previous question, what would be the KK genotype frequency at the adult? a) 0.090 b) 0.270 c) 0.325 d) 0.360 e) 0.529 3)Following up on the previous question,…
A follow-up study indicated that the effect of environmental stochasticity on extinction risk was negatively correlated with body size (i.e., larger shrews were less affected by environmental variation). Does this make biological sense? Why or why not
Almost all birds starved during the dry season depicted here. What type of selection would have been present if only the intermediate-beaked birds had survived (instead of the small- and large-beaked birds)?
Let us assume that there is a sub-population of wasps that are evolving towards a longer and thinner ovipositor i.e. longer ovipositors are increasing in frequency in the species. Provide a hypothetical natural selection scenario that would result in such a transition from a thick and short ovipositor to a longer and thinner ovipositor. In your answer, you should include pertinent information on: The Original Population2. Selection Pressures3. Differential Reproductive Success4. Selective Advantages5. Direction of Evolution6. Expected pattern of Evolution
The graph shown here is from a natural selection lab in which students "hunt" for candy in different simulated environments. Examine the graph and answer the questions below it. Approximately how many of each candy species were present in generation 1 (round to the nearest 10)? Which candy species was the least able to hide from the predators in Generation 3? Which candy species had the best survival rate throughout the first four generations of the simulation? Does this data support the hypothesis that Snikers were the most fit for the simulated environment? Please answer yes or no
Lamarck's hypothesis about how species change over time was Group of answer choices a. based on the assumption that an organism's phenotype was determined by both its genes and the environment b. correct because it proposed that characteristics acquired in one's lifetime could be passed on to offspring c. ahead of its time because it explicitly focused on changes in genotype frequencies in a population d. based on the assumption that an organism's phenotype was determined solely by its genes e. incorrect because it proposed that characteristics acquired in one's lifetime could be passed on to offspring t
Ancestors of the beach mouse mayhave exhibited variations in their coat color. Because of the prevalence of visualpredators, the better-camouflaged (lighter) mice in the beach habitat may havesurvived longer and been able to produce more offspring. Over time, a higher andhigher proportion of individuals in the population would have had the adaptation of lighter fur that acted to camouflage the mouse in the beach habitat.
The vgll3 locus is responsible for the age at which salmon mature. The vgll3 L allele causes salmon to mature earlier. This is the data on the frequency of the vgll3 L allele collected from Alaskan salmon over the course of 30 years. Which of the following describes whether this population is at Hardy-Weinberg equilibrium, and why? A - This population is not at Hardy-Weinberg equilibrium because there is evidence of selection against earlier maturing salmon. B - This population is at Hardy-Weinberg equilibrium because there is no overall trend in allele frequency over the study period. C - This population is not at Hardy-Weinberg equilibrium because there is evidence of the introduction of new mutations causing salmon to mature earlier. D - This population is at Hardy-Weinberg equilibrium because including salmon from six rivers ensures a large and genetically stable population.
