- O Ability to see UV light Grades lembers nferences In the 1890s, hunting reduced the northern elephant seal population to only 20 individuals. Due to conservation efforts, their population size today is above 30,000. How would the genetic diversity of the northern elephant seal population compare to the genetic diversity of the southern elephant seal population, which was not heavily hunted? * g Online sela on Periods 1 and 2 riods MP1, Highschool The northern elephant seal would have much less genetic varlation than the southern elephent seal. hool MP3, The southern elephant sea would have much less genetic variation than the northern elephant seal. AP4 O The two populations would have similar genetic variation Thu Fri The southern elephant seal would have stable genetic variation because it is in Hardy- Weinberg equilibrium. You are studying two variations of banana slugs. They have similar coloration and ATthnh thare.nhveieallu obl lein thecomeheh US A 9:0Pikas are small mammals that live at high elevations on the talus slopesof mountains. Most populations located on mountaintops in Coloradoand Montana in North America are isolated from one another: the pikasdon’t occupy the low-elevation habitats that separate the mountaintopsand don’t venture far from the talus slopes. Thus, there is little gene flowbetween populations. Furthermore, each population is small in size andwas founded by a small number of pikas.A group of population geneticists proposes to study the amount ofgenetic variation in a series of pika populations and to compare theallelic frequencies in different populations. On the basis of the biologyand distribution of pikas, predict what the population geneticists willfind concerning the within- and between-population genetic variation.Snakes evolved from ancestors who had the ability to walk. Some snakes, in fact, still have small pelvis and leg bones that are remnants from this ancestor. What are these caled? Vestiglal structure O Homologous strucre O Sympatric structure O Molecular homology In the 1890s, hunting reduced the northern elephant seal population to only 20 individuals. Due to conservation efforts, their population size today is above 30,000. Of what is this an example? Founder effect
- In a particular population of mice, certain individualsdisplay a phenotype called short tail, which is inherited as a dominant trait. Some individuals display arecessive trait called dilute, which affects coat color.Which of these traits would be easier to eliminatefrom the population by selective breeding? Why?Which scenario would be a moder nexample of Lamarckianismm? A strain of houseflies resistant to insecticides emrges Squirrels separated by a river are found to be unable to interbreed Snails are found to have thicker shells generations after the introduction of a predator A son is bornw ith a portion of his right index finger mssing -- the same portion that was severed from his father's hand in an accident.A powerful windstorm moves through a densely populated white oak forest. The oaks in this forest have either smooth or rough bark. The storm randomly knocks down 50% of the white oak trees. The remaining oaks grow and produce seeds that germinate and fill in spaces in the forest. All of the new oaks have smooth bark. Which of these processes is described in this example? O genetic drift O natural selection O mass extinction O geographic isolation
- If these conditions held constant – what would the expected heterozygosity be in thepopulation today (2018 to deal with a clean integer value for generations)?1b. In 1884 the population had grown to 106 when disaster struck the island. Of the 19 adult menon the island, 15 were in the same fishing boat that capsized, leaving only 4 adult men alive onthe island. These desperate times may have changed the sex ratio of the breeding population onthe island. Let’s say that now, each man fathered children with an average of 1.5 differentwomen (male:female ratio of 1:1.5). If we start back with a heterozygosity of 0.5 from this point,given the effective population size on Tristan da Cunha, what is the expected heterozygosity inthe current population 7 generations later?1c. The scenarios described in 1a and 1b are examples of which two evolutionary phenomena,respectively?@ 2 W S Rehpogs are mythical creatures. They are small and not very smart. Rehpogs live on the ground in a flat, warm habitat. Their fur texture and color ranges from thick purple fur to thin pink fur, depending on allele distribution. The dominant fur allele (R) codes for thick purple fur. The recessive allele (r) codes for thin pink fur. REMEMBER: a phenotype (fur color) is the physical expression of a genotype (two- letter code for the alleles present in that individual). Each individual has two alleles for fur color: X RR genotype is homozygous dominant = Thick purple fur phenotype Rr genotype is heterozygous = Thick purple fur (because of the presence of one dominant allele) rr genotype is homozygous recessive = Thin pink fur (because of the absence of a dominant allele) For the purposes of this experiment, Rehpogs mate once per year and produce two offspring each year. Rehpogs are monogamous, faithful and fertile. # 3 e d C C $ 4 r f V % 5 t g Oll 6 b y h & 7 O 8 n JL u i j O L m…Deer mice are usually found mice that live in the Sand Hills of Nebraska, however, have evolved a lighter coloring, the result of a change in one gene. The initial population of deer mice in the Sand Hills was probably dark brown, like all other deer mice. What was the driving force behind the evolution of this population?* the woods and are dark brown in color. The deer O Mutation O Speciation O Equilibrium O Predation
- Imagine that you are asked to manage a population of wolves that have taken upresidence on an island off the coast of Alaska. Because prey resources are limited, theisland will support only about 50 wolves at any one time. What steps would you take toprevent inbreeding and genetic drift in the population in the future?Two species of fish had recently undergone sympatric speciation. The males of each species had a different coloring through which females could identify and choose a partner from her own species. After some time, pollution made the lake so cloudy it was hard for females to distinguish colors. What might take place in this situation?A human protein, MC1R is responsible for telling human cells what type of pigment proteins to produce. One version of MC1R causes cells to make red pigments, while another version causes our cells to make black pigments. The red version causes red hair. The black version causes black hair. How did these 2 versions come to exist? O gene flow O mutation O natural sclection O genetic drift 近
