- 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?Consider the first copy of an allele for insecticideresistance that arises by mutation in a populationof insects exposed to an insecticide. Is this mutation an adaptation? If, after some generations,we find that most of the population is resistant,is the resistance an adaptation? If we discovergenetic variation for insecticide resistance in apopulation that has had no experience of insecticides, is the variation an adaptation? If an insectpopulation is polymorphic for two alleles, eachof which confers resistance against one of twopesticides that are alternately applied, is thevariation an adaptation? Or is each of the tworesistance traits an adaptation?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.
- The image shows the beak shapes of four different finches observed by Charles Darwin on the Galapagos Islands. Darwin observed that broad-beaked finches prefer to eat large, hard seeds, while finches with narrow beaks eat small, soft seeds. What did Charles Darwin infer from this study that led to the development of the Theory of Evolution? O Finches with broad beaks have higher survival rates than finches with narrow beaks. O Finches with narrow beaks gradually evolve broader beaks to feed on all types of seeds. O The finches evolved from different ancestors with different shapes of beaks. O The finches evolved from a common ancestor and developed different beak shapes to adapt to the food available. •O 12:07 hp 女 -> Ce esc & % #3 8 6 7 4. 2 r t y eMales of different species of the fruit fly Drosophilathat live in the same parts of the Hawaiian Islandshave different elaborate courtship rituals. These rituals involvefighting other males and making stylized movements thatattract females. What type of reproductive isolation does thisrepresent?(A) habitat isolation(B) temporal isolation(C) behavioral isolation(D) gametic isolationThe elaborate tail of the peacock (Pavo cristatus) is approximately 120 cm to 150 cm long, while the tail ofthe peahen is quite short. The long tail reduces the male bird’s ability to maneuver and fly and makes him moreconspicuous to predators. Suggest at least one reason why this cumbersome structure has not been eliminatedby natural selection.
- Imagine that you are an evolutionary biologist currenyly studying a particular species of snake on an island off the coast of Durban, South Africa and that you have information indicating that1000 years ago, the same species of snakes in that island was observed to exist in a variety of colours (Red blue,yellow green) and that most of the snakes were blue. This same species of snakes and the same mixof colours were also found on the mainland (i.e Kwazulu Natal) Assuming that all the snakes are descended from an ancestral blue snake, explain this change in colour frequency (evolution) as though it were based solely on each of the following processes. a. Natural selection b. Bottleneck effect c. Founder effectWhat behavioral trait(s) prevents interbreeding between different finch species?What type of geographic barriers could have led to the speciation of finch in the Galápagos Islands?
- In a population of lizards, color is genetically determined. The current population has two two phenotypes: blue and yellow. Which of the following scenarios could result in evolution by migration? O A disease indiscriminately reduces the population by 90%. Birds are better able to see and therefor prey on blue lizards The population is joined by individuals from a nearby population that has an allele for a red phenotype. Females preferentially mate with individuals exhibiting the blue phenotype.How do you think the one species of finch evolved into many different species, each with its own advantages?In a populationof manatees, short whiskers are recessive to long whiskers. There are estimated to be only 4387 manatee left in the world. Of these, 827 have short whiskers. What is the frequency of homozygous recessive individuals?
