Which of the following BEST describes the relationship between genotype, phenotype, traits, and the environment? O Organisms acquire traits during their lifetime that alter their phenotype. This allows individuals to better adapt to their surroundings, and to pass on their phenotypes to their offspring regardless of their genes. An organism's phenotype is largely determined by its genes, or genotype. The relationship between an organism's phenotype and its environment determines the frequency of traits in a population. O The relationship between an organism's environment and its genotype determines the type of phenotype it will develop. Phenotypes are largely determined by the environment and organisms display traits that are unrelated to their genes.
Fred and George are arguing over evolution. Fred posits that evolution can occur in any population as long as all members gradually undergo change. George disagrees; he thinks that individual memebers of the population do not change but instead have offspring with the trait(s) of interest and thus a population evolves over generations. Who is right? Choose the best answe a. Fred is right! As members of the population respond to the environment, they change to suit it better O b. Fred is right! All memebers of the population must change aroudn the same time O c. George is right Evolution occurs over generations as only the beneficial traits are passed onto the next generation. O d. George is right! Individuals don't change their alleles, but the offspring they have contributes to the change in population allele frequencies
Which of the following is NOT principle of Darwinian evolution? OOffspring resemble their parents more closely than unrelated individuals. Darwinian evolution fully describes where all living things come from. O In any given environment, some individuals are more successful at surviving and reproducing than others. There is variation in morphology, physiology, and behavior among individuals in a population.
Background: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question. Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________. What goes in the blank
Natural Selection is an evolutionary force that acts at phenotypic and genetic level. At the genetic level, which of the following statements is correct about the action of this force: O Selection is random and doesn't need genetic diversity in the population O Selection decreases the genetic diversity in the population O Selection is always negative and makes traits undesirable O Selection creates new alleles in the population
In the study of genetics, a model organism is one in which hypotheses can be tested and the results are usually true of most other organisms. For examining heredity and how different alleles affect traits in a population, a good model organism is one that has a short generation time and many offspring O is most like a wild population has only a few offspring that can be studied extensively most resembles humans

What would happen if a mutation created a new allele that decreased fitness? * The new allele would have to change back to an allele of higher fitness so the possessor of that allele could maintain its fitness. The individual with the new allele would wait for an environmental change so that its fitness would increase again No answer The new allele would decrease the fitness of the individual that possessed it, and that individual would have few or no offspring The new allele would spread through the population and decrease the fitness of that population
Evolutionary fitness refers to? the contribution an individual makes to the gene pool of the next generation the ability of an organism to survive in a particular environment Othe ability of an organism to adapt to changing environmental conditions
If vestigial traits are no longer useful to an organism, why don't they evolve out of the population? * Individuals with the trait have developed new ways to use them. Individuals that have the trait continue to survive and reproduce, and they pass on th genes for that trait to the next generation. Individuals that have the trait must have some sort of evolutionary advantage. The individuals that have the trait become less common over time.

1. Definitions of phenotype, genotype, allele, gene, microevolution, macroevolution 2. Know that in humans, most of the genetic variation is observed within populations, and know why that is. 3. Know the 4 processes of evolution (3 neutral + natural selection) 4. Know that evolution isn't progressive and doesn't necessarily lead to more complexity 5. Know that evolution can lead to traits that decrease survival (ex: sexual selection)
