Practice bottlenecks, natural selection, outbreeding career test prep for mcat test. Choose the one alternative that best completes the statement or answers thequestion. Differences due to diet, health, age or accident that have no affect on an individual's ability to survive and reproduce. A group of mice becomes separated by the formation of a river. Which of the following is an example of living fossils? Genetic drift does not require the presence of variation.
For a population to be inHardy-Weinberg equilibrium, the assumptions are that the population must bevery large to counteract the effects of genetic drift and mutation and verylarge randomly breeding population with random mating no sexual selection will ensure sufficient gene flow among a large number of individuals. Which of the following are the most distantly related to one another? B You may contact Dave Rudge either by , by phone 616 -387-2779 or by fax 616 -387-5609. Which of the following concept is attributed to Charles Darwin? According to the Hardy-Weinberg rule, what will be the ratio of these alleles in the gene pool in future generations, provided all the guinea pigs reproduce? A branch shifts along the X axis. They are analogous because while each carries out the same function flight , this trait has arisen independently as a result of convergence i. Learn with multiple choice question: process by which individuals that have beneficial characteristics for reproduction in a specific environment and can produce more offspring is called, online certificate courses with options natural selection, reproduction, evolution, inheritance for medical students with eCourses' distance education to improve interactive problem-solving skills. It is possible that in the cave there is a source of pollution that increases the mutation rate for a gene that makes salamanders blind.
If antibiotic use werestopped, what would you predict would happen to these S. Philosophie zoologique we was written by 1. The image illustrates what evolutionary concept? Some members of the ancestral population had larger beaks than others. Sexual selection isselection on traits that increase success in competing for mating opportunities i. Ó I donÕt want the 3-word answer, I want you tostate the conditions more completely. Directions: Answer the following multiple choice questions by choosing the letter of the response that represents the best answer to the question. Thus, traits arise through sexual selection that may be detrimental tosurvival, but endow the possessor with an advantage in gaining reproductivesuccess — i.
The dog breeds we have today were developed through: natural selection artificial selection selective breeding sexual selection acquired selection 10. The bees that pollinate this plant prefer also prefer pink to whiteflowers, so that Claytonia with pink flowers have greater relative fruit set reproductive success than Claytonia with white flowers. In science, theories are: an educated guess a known fact absolute and unchangeable the best explanation for a set of data or observations 5. Genetic drift does not involve competition between members of a species. D It is passed on through evolutionary history with only minor modifications.
C A new, isolated population of fruit flies is founded by a small group ofcolonists, which then diverge from the ancestral source population. A Animals have behavioral rituals that result in mate recognition. There may be some statements in science that are useful even if they are not falsifiable or refutable in principle. Most abundant organic compound on earth is a Protein b Cellulose c Steroids d Lipids 20. Which of the following is not a source of variation in a population? Which of these would make a good candidate for a molecular clock? What's the difference between natural selection and sexual selection? Male deer evolve antlers that are not used to defend themselves against predators.
Members of the ancestral population that colonized the cave differed in their ability to see. This is known by which law? Natural selection depends upon the presence of variation, artificial selection does not. Patti and Selma have hanging ear lobes. It is not important from an evolutionary standpoint. All species have a common ancestor. A lion who cares for his cubs, two of who live to adulthood.
B The frequency of resistant forms will increase in these populations. Similarities between two species may be due to common descent, without indicating how closely the two are related to one another. Lamarck's contribution to the theory of evolution was the concept of a. The first fish species and every living organism that looks like a fish. It usually occursbecause the two adjacent habitats have such different selective pressures thatintermediate forms the product of inter-breeding between the two populations are selected against at a severe disadvantage. Scientists recognized that once one thinks about species as populations, rather than individuals, there is no incompatibility between them.
A birdÕs wing and a dogÕs leg are homologous traits in that the bonestructure for both was present in a common ancestor. The ancestors of this bird species encountered a tree with larger than average sized seeds. Which of the following are difficult to explain in terms of natural selection? Marge dies her hair blue. D Animals and fungi are more closely related to each other than animals are toland plants. What's the difference between genetic drift and change due to natural selection? Evolution Practice Test Evolution Practice Test Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. Apu is a tongue roller, but his brother Sanjay is not. Itcan produce advantageous, neutral, and disadvantageous changes.
