- Explain how negative frequency-dependent selection works.arrow_forwardExplain your reasoning or evidence for why you think Biologists classify specific forms of traits as good or bad. For example, long tails in cats could be classified as good and short tails as bad.arrow_forwardImagine that genetic technology advances to the point where the genetic profile of an individual can be easily obtained, and that we have a full understanding of how genes interact to influence our health. Based on this genetic information alone, how reliably do you think we would be able to predict a person's chance of getting a specific disease? Where do you think this type of genetic profiling would lead with respect to selection of offspring or genetic superiority?arrow_forward
- Darwin was the first person to note that evolutionary outcomes are probabilistic, meaning that they depend on the likelihood of outcomes rather than on certainties. Explain what this means in the context of Darwin’s theory of how evolution occurs? That is, how is Darwin’s theory is dependent upon the chances of a certain outcome and not on the absolute certainty of any particular outcome?arrow_forwardSickle Cell Anemia is an example of "balancing selection" in which natural selection works against the extremes of a trait and favors the intermediate phenotype (e.g. the heterozygous "carriers" of the sickle cell trait) True or false?arrow_forwardWhich of the following statements regarding selection is true? Incorrect answer - selection will always result in a change in allele frequencies. Correct Answer - The direction and magnitude of allele frequency change due to selection can be predicted. Question: Please explain in detail why the correct answer is correct and please explain why the incorrect answer is not correct.arrow_forward
- How is a theory different from a truth? Does the use of "theory" in biology mean the concept is in doubt? Explain using examples.arrow_forwardA biologist set up an experiment to study 3 lizards. On the first day of his study, he measured the mass of the three spice mens. He made sure that all lizards weigh 100 grams. Then the lizards were put into individual cages with the following conditions. 1. What is the independent variable? 2. What is the dependent variable? 3. Which among the set ups is the control set up? 4. Which of the item is/are the experimental set ups? 5. Based on the result of the experiment, what conclusions can be drawn from this?arrow_forwardIs the evolution of behavioral traits versus other traits, like morphological trait, likely to be different? Explain in details why the answer may be yes or no.arrow_forward
- 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.arrow_forwardJean-Baptiste Lamarck introduced a theory about inheritance in the early 1800s. Which of the following accurately describes his Theory of Acquired Characteristics? a. Offspring traits are the result of the blending of traits from the parents. b. Offspring traits are the result of parent individuals modifying their traits due to use or non-use. c. Traits are acquired from genes, and arise only from the mother not from the father. d. Traits are acquired from grandparents and skip the parent generation altogetherarrow_forwardBiologists classify specific forms of traits as good or bad.
