BME Quiz 16 Questions: Population Genetics 1) To determine evolutionary relatedness, the anatomical record looks at different species and compares -Structures that may be present at specific developmental stages -Vestigial features that may no longer have a required function in a particular species -Structures that have a common origin -All of the above 2) Measurements show that male lazuli bunting birds are more slightly aggressive towards bright or intermediate colored young males versus dull colored young males moving into their territory and building nest sites. Females prefer to mate with bright colored males, but the males also need to have a nesting site ready. When nesting sites are in short supply, fewer and fewer lazuli buntings with intermediate colaration are seen. This is an example of -directional selection -stabilizing selection -disruptive selection -none of the above 3) Black Peppered Moths were selected at one period of time because birds had a more difficult time detecting them on trees darkened by soot and air pollution. -True -False 4) Microevolution -Is evolution of bacteria -Is evolution of invertebrates -Is learning to hit a slider after multiple at bats -Is the change in allele frequencies in a population over time 4b) Microevolution Is evolution of bacteria is the change in gene number in a population over time is the change in chromosome number in a population over time Is the change in allele frequencies in a population over time 5) Natural selection -Can be directional -Requires traits with some alleles -Acts on phenotypes -All of the above 6) The fossil record contains many fossils that link major groups of species. -True -False 7) Allele frequencies can change due to -genetic drift In small populations -immigration and emigration -nonrandom mating -All of the above 8) The Hardy Weinberg Principle requires which assumptions -Large populations
