- Which type of selection is represented by a population of flower that grows either short stems or long stems? Stabalizing Directional DisruptiveWhich of the following is not a characteristic of r-selected species. O mature early O mature late O more offspring O smaller offspringWhich one species is K-selected, not r-selected? O Dandelion Elephant Guppy O Rabbit
- Which type of selection best describes the shift in peppered moth from the light form to the dark form following the industrial revolution? Directional Stabilizing Disruptive 58In response to warmer spring temperatures, a plant species is flowering earlier in the year than it would have historically. However, its primary pollinator, the bumblebee, has not been as responsive to temperature changes and continues to emerge at the same time as usual. As a result, peak floral displays have finished prior to pollinator emergence. This change in plant-pollinator interactions is an example of: O Interspecific evolution O Sympatric speciation O Uncoupling of interdependent species O HeterochronyAre differences in migratory orientationwithin a species genetically determined?
- Which of the following traits are more likely to become widespread in the next generation? O acquired traits that improve reproduction acquired traits that improve survival such as long neck in Giraffe inheritable traits that improve survival and reproduction albino (no pigment) in tree squirrel O wider black stripes in ZebrasThis is a picture of a plant that grows in the tundra with the common name arctic willow. Plants that evolved in the tundra would be classified as stress tolerators, rather than competitors or ruderals in the classification diagram we discussed in class that is based on three factors, stress, competition, and disturbance). What traits would you expect the arctic willow to have relative to competitors and ruderals? Select all that apply. O Arctic willow allocates a greater proportion of its resources to make leaves and roots that to flower and make seeds Arctic willow is less likely to reproduce vegetatively than an annual plant adapted for low competition, low stress and high disturbance Arctic willow will grow slowly even if it grows in optimal conditions Arctic willow is likely to reproduce later in its life cycleWhich of the following features is unlikely to promote the evolution of selfing? Fisher's transmission advantage of selfing alleles Strongly deleterious recessive alleles Reduced floral form such as petals and floral displays Colonization of a novel habitat without pollinators
- ed to court femaigs and to defend tertory What kind of traits result from Competition Tor mates Sexually selected traits lin most species males can potentially have a huge number of offspring, but in order to realize even a fraction of their reproductive potential, they have to compete with other males (because the number of female eggs is a limiting factor, and because females evolved to be picky). Omaments on males and structures used to compete for mstes (antlers) selective pressure on males from competition with other males over females? - Behaviors such as bower construction, that are -Energeticaty expensive --Ridoulously conspiouous -Am lkely to reduce chances ofsurvival Why do males from very distant species have similar traits?

Their short, heavily muscled neck prevents them from lowering their head to the ground to graze on grass or drink water from a pond. Elephants have evolved long trunks to reach grass and water. Which kind of selection is responsible for elephants' long trunks? O Stabilizing O Diversifying O DirectionalImagine 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.a)What is the size of the population?b)Do the alleles have a simple dominance relationship? Describe.c)What are the frequencies of the two alleles?d)Is the population in Hardy-Weinberg equilibrium?If not, how do you know, and what might be the cause?
