QUESTION 8 Morphological differences are abundant among many species. We make assumptions about why adaptations exist, but to understand whether a specific trait is a adaptive and why, researchers must create experiments that have all the following, EXCEPT: a. replication of each treatment to ensure reliability of results. b. hypotheses that are testable and falsifiable. c. include control groups. d. exceedingly small sample sizes in each treatment group. e. experimental design that enables all full interpretation of differences.
QUESTION 22 Tiktaalik and Archaeopteryx are very important transitional forms. They provide evidence for evolution through examples of: a. microevolution b. macroevolution c. migration d. speciation
Question 13 Natural selection occurs 1. when a new genetic variation occurs that allows individuals to have a reproductive and survival advantage 2. when a factor in the environment alters the genetic information in DNA of all members of a species 3. when a small number of individuals of a population break away and form a new population
QUESTION 16 You are examining a beloved population of trillium in the backyard of your childhood home. You recall as a child that flowers were bright white. As you return to the population you note that many (but not all) of the flowers have a faint purple vertical stripe in the middle of each petal. List each of Darwin’s postulates and what must be true about your population if it has undergone evolution by natural selection for petal color.
QUESTION 38 All of the following are true statements about the Hardy-Weinberg Equilibrium (HWE) principle, EXCEPT: a. HWE concludes that allele frequencies change over time. b. HWE principle assumes that all of the individuals in your population survive and reproduce equally. c. HWE concludes that if given the allele frequencies we can then accurately predict the genotype frequencies in the population. d. HWE principle assumes large, completely isolated populations.
QUESTION 44 Naegleria fowleri, also known as the ‘brain-eating amoeba’, causes deathly amebic meningoencephalitis in humans. However, this pathogen is typically free-living and humans cannot transmit them to any other potential host. What type of virulence evolution hypothesis does this demonstrate? a. Coincidental evolution hypothesis b. Short-sighted evolution hypothesis c. Cost/trade-off evolution hypothesis
QUESTION 23 Allele frequencies for eye color in a population of hippogriffs is p=0.73. How many individuals would you expect to be heterozygous in a population 150? (Assume HWE)
Question 3. There are 100 students in a class. Ninety-six did well in the course whereas four blew it totally and received a grade of F. Sorry. In the highly unlikely event that these traits are genetic rather than environmental, if these traits involve dominant and recessive alleles, and if the four (4%) represent the frequency of the homozygous recessive condition, please calculate the following: A) The frequency of the recessive allele. B) The frequency of the dominant allele. C) The frequency of heterozygous individuals. Question 4 Within a population of butterflies, the colour brown (B) is dominant over the colour white (b). And, 40% of all butterflies are white. Given this simple information, which is something that is very likely to be on an exam, calculate the following: A) The percentage of butterflies in the population that are heterozygous. B) The frequency of homozygous dominant individuals. Question 5 A rather large population of organisms have 396 red-sided individuals…
QUESTION 16 In Tipper's negative priming task, participants are ____________ to say the name of a probe object when that object was just previously _______________. a. slower; attended to b. faster; ignored c. slower; ignored d. faster; attended to e. none of the above
QUESTION 18 Describe: Population aging and increased longevity are creating more multi- and intergenerational families in the U.S. Give two examples of ways in which family structure and family roles are changing because of these changes.
Question 10 In a population of mountain lions, 9% of the individuals suffer from a disease caused by a recessive allele (aa). Calculate the frequency of both the dominant and recessive alleles. 2. What is the percentage of homozygous dominant individuals and what is the percentage of heterozygous individuals in the population?
QUESTION 34 You are examining a nematode population in the compost behind your house. You notice that in the nematode population there are two alleles at a locus you think may play a role in movement. You find that individual nematodes either always turn right or always turn left, but never both directions in their lifetime. Interestingly, this behavior correlates with reduced heterozygosity at that locus in the population. What type of selection is likely acting on your locus of interest? a. Selection against recessive alleles b. Frequency-dependent selection c. Underdominance d. Overdominance
