Zooplankton (small animals that live suspended in the water) are sometimes isolated in small ponds caused by glaciers, called prairie potholes. Movement of zooplankton between these habitats is very limited. Because of the small size of zooplankton, each pothole can maintain a very large population. There are no known traits that females use to determine male quality, when males are present, nor is there any obvious sign of male-male competition. When assaying the populations for genetic diversity, you find that all have the same alleles and no new alleles have appeared since these habitats were colonized. At this time, no known traits are under selection. If all of these things are true, then are these populations likely to exhibit changes in allele frequency in the immediate future? Yes, they will exhibit shifts in allele frequency in the next generation or two in random directions No, if these conditions continue the allelic frequencies will not change Yes, they will exhibit shifts in allele frequency with imminent declines in allelic richness O It is impossible to guess at, let alone predict how allelic frequencies will change, even if these conditions persist

Imagine that you are a conservation biologist responsible for the well-being of a bufello herd consistingof 100 mature males and 100 mature females. In this herd, there is no appreciable mutation, there isno migration in or out, and there is no selection. At the Fuzzy gene locus, there are two alleles, G and E.Homozygous G individuals have fuzzy fur, homozygous E individuals have rough fur, and heterozygoteshave shaggy fur. Suppose you survey the herd and find that there are 44 fuzzy individuals, 72 shaggyindividuals, and 84 rough individuals. Suppose you watch the buffalo and discover that while all the females breed, a small number of males(10) establish breeding harems, while the other males do not breed.a) What is the effective population size of this herd? That is, what size "ideal" population ofbalanced sex ratio would have genetics similar to this population?b)How does the effective population size compare to the actual population size?c) Under Hardy-Weinberg equilibrium, what…

Female spotted sandpipers aggressively court males and, aftermating, leave the clutch of young for the male to incubate. Thissequence may be repeated several times with different males untilno available males remain, forcing the female to incubate her lastclutch. Which of the following terms best describes this behavior?(A) polygyny(B) polyandry(C) promiscuity(D) certainty of paternity
When Charles Darwin discovered the various finch species on the Galápagos islands, he was surprised to find so many different but related species in such a small geographic area. Which of the following best illustrates the correlation between competitive advantage and an individual’s traits in a particular environment? Different islands had very different food resources available, and only individuals that were adapted to eat those food resources survived and reproduced on that island. Finches had no natural predators on the island before Darwin’s voyage, allowing them to prosper on the islands. Competition between different species for food resources led to resource partitioning of the ecosystem. Mating behaviors in finch species ensure that different species of finch will not interbreed with one another.
A group of 50 men and 50 women establish a colony ona remote island. After 50 generations of random mating,how frequent would a recessive trait be if it were at afrequency of 1/500 back on the mainland? The population remains the same size over the 50 generations, andthe trait has no effect on fitness.
In 1983 a population of dark-eyed junco birds became established on the campus of the University of California, San Diego (UCSD), which is located many miles from the junco's normal habitat in the mixed-coniferous temperate forests in the mountains. Juncos have white outer tail feathers that the males display during aggressive interactions and during courtship displays. Males with more white in their tail are more likely to win aggressive interactions, and females prefer to mate with males with more white in their tails. Females have less white in their tails than do males, and display it less often. (Pamela J. Yeh. 2004. Rapid evolution of a sexually selected trait following population establishment in a novel habitat. Evolution 58[1]:166-74.) Refer to the paragraph on dark-eyed junco birds. The UCSD campus male junco population tails are about 36% white, whereas the tails of males from nearby mountain populations are about 40-45% white. The founding stock of UCSD birds was likely…
A population of dark-eyed junco birds became established near the California coastline, many miles from the junco's normal habitat in the mixed-coniferous temperate forests in the mountains. Juncos have white outer tail feathers that the males display during aggressive interactions and during courtship displays. Males with more white in their tail are more likely to win aggressive interactions, and females prefer to mate with males with more white in their tails. The coastal male junco population tails were, on average, 36% white; whereas the tails of males from the mountain populations averaged 40-45% white. Which of the following factors is the most likely original cause of the difference between the populations if the trait is inherited? Multiple choice (one answer is correct) 1. a founder effect in the coastal population 2. gene flow between populations 3. mutations in the coastal population 4. a bottleneck effect in the coastal population
You are surveying of the turtle species identifies several breeding populations in different habitats across the island. After a very warm summer of 2020, you observe that the hatchlings from low-elevation nests are mostly males, whereas hatchlings from higher elevations have an equal female-to-male sex ratio. As a bit more background, temperature influences the sex ratio in some turtle species, a phenomenon called temperature-sex determination (TSD). With this knowledge, you hypothesize this new turtle species exhibits TSD, and that eggs incubated at low elevations during the warm year experienced a high enough embryonic temperature to skew the sex ratio. To test this, you collect 20 newly laid eggs in early 2021 & take them back to the lab to conduct an experiment to test your hypothesis that this species exhibits TSD. Assume you know the average nest temperature in the wild, and you have access to multiple incubators Design an experiment to test the hypothesis that this turtle…
Among a population of tadpoles, the correlation coefficient for size atmetamorphosis and time required for metamorphosis is −0.74. On thebasis of this correlation, what conclusions can you draw about therelative sizes of tadpoles that metamorphose quickly and those thatmetamorphose more slowly?
The endangered Amargosa River pupfish (Cyprinodon nevadensis amargosae) lives in Death Valley, where different populations of the species live in total isolation from one another in tiny permanent pools and short stream segments (Lema and Nevitt 2004). Although these populations have been separated from one another for only 400 to 4000 years, males in some places aggressively defend territories and court females drawn to them, while males in other populations are not aggressive toward one another and do not defend territories. How could these changes occur so rapidly? How might you establish experimentally that the hormone arginine vasotocin (AVT) decreases aggressive behavior in pupfish? If the hormone does lower aggression in this species, what predictions could you make about AVT or about AVT receptor protein differences between territorial and nonterritorial males of the same species? please don't write from any online source
