- In order for a trait to evolve via natural selection, which of the following must be true regarding the trait? (this is a multiple answer question - so select all correct) Group of answer choices There must be variation in the trait. The trait must make the organism survive longer than organisms with different traits. The trait must confer a reproductive advantage on the bearer of the trait. The trait must be heritable. The trait does not necessarily need to be passed down to offspring.Which of the following factors are required in order for evolution to occur? a. Individuals within a population must be receptive to change and collectively determine which trait(s) is/are to be modified in subsequent generations b. Genetic variation within a population must exist or have the potential to arise, and shifts in allelic frequencies will take place or have the potential to take place c. Individuals within a population should be able to reproduce effectively (i.e., without barriers to reproduction existing) d. Both A & B e. Both B & CThe dog breed West Highland Terrier is a product of artificial selection. Give a brief description of the breed and its desired traits. What wild ancestor did it come from? Was it produced with selective breeding or genetic engineering (i.e. genetically modified)? What are the benefits of artificial selection in this case? Are there potential negative consequences?
- Natural selection and artificial selection or selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. Changes in genetic traits have occurred over generations through both natural selection and selective breeding although the occur through different means. What characterizes only artificial selection? Choose all that apply. A) chickens that lay larger eggs are favored B) selection increases the chances of surviving C) selection make a species stronger and fit for survival D) selection favors the desired characters in the new organismsAccording to the Hardy-Weinberg Equilibrium Equation, all of the following slow down or stop evolution EXCEPT (choose as many as apply): Group of answer choices very small population very large population no one leaves or comes into the population everyone has equal numbers of offspring there are no mutations there are lots of mutations there is non- random matingIdentifying genes like HMGA2 is important, because it is evidence of natural selection. How does it demonstrate that natural selection occurred in Darwin’s finches? Scientists mutate and modify the gene in the lab to see how changes might occur to the organism. Scientists identify different forms of the gene in individuals from the same species and observe how it shows up as a trait. Scientists study similar genes that also impact the same traits to see how they work together and influence one another. Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment. Need some help on this one.
- Do you think the human race is continuing to evolve in a Darwinian, genetic sense? Are the genes of our species changing? Do not just write "yes" or "no," but explain why you think so. In addition, include in your explanation of how the mechanisms of evolution, such as natural selection, would be at play.Black lava rocks only appeared in the desert about 1000 years ago. If the first dark-colored rock pocket mouse had a 10% advantage, about how long would it have taken for nearly all of them to have dark-colored fur? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a 10,000 years. 1000 years. 100 years. It depends on how fast new mutations occur. This cannot be estimated because evolution is random. FullscreenWhich of the following statements about the grandmother hypothesis is correct? This is a hypothesis used to explain why grandmothers tend to live longer than grandfathers. For this hypothesis to work, a grandmother will need to have an antagonistic pleiotropic mutation that extends her lifespan but also lessens her physical activities. Because grandmothers are older, so they tend to contribute less in a family. That is, grandmothers are usually a drain of resources for a family. The evolution of monthly menstrual cycle in human females is seen as an example explained by the grandmother hypothesis. None of the above
- Evolution takes place through a combination of mechanisms at the level of populations. This process consists of a change in allele frequencies in a population over time. Consider the following scenario: You are observing a population of wild mice that has a dominant allele which produces white-colored fur, while the homozygous recessive alleles result in dark brown fur. Genetic studies have indicated that this gene for fur color follows Mendelian inheritance. Originally, the mice population was comprised of over 80% of white mice in a dark forest environment. As the local fox population increased, you noticed that there were fewer white mice and more brown-colored mice. By the end of your observation period of six months, you notice that brown-colored mice now make up over 60% of the total mice population. Based on this scenario, explain what force of evolution is at workEvolution takes place through a combination of mechanisms at the level of populations.

Based on this scenario, explain what force of evolution is at work. 2. Are you observing microevolution or macroevolution? Explain your answer.Which of the following statements about the forces that drive evolution is TRUE? Unlike the other evolutionary forces, natural selection is the only force that improves the match between the organism and its environment. Unlike the other evolutionary forces, gene flow is the only force that causes populations to become more different. Unlike the other evolutionary forces, mutation is the only force that decreases genetic variability. Unlike the other evolutionary forces, nonrandom mating is the only force that changes allele frequency.
