- 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 & Carrow_forwardDiscuss the significance of mutations and explain the role of the environment in the evolutionary process. (Hint: Consider Lenski's study and what is demonstrated. Do not re-tell Lenski’s study)arrow_forwardAccording 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 matingarrow_forward
- Describe how populations with substantial genetic differences can form. What is the role of natural selection?arrow_forwardIdentify and describe (explain) the four forces of evolution. Imagine a scenario where a population of lizards encounters another population of lizards and interbreeding occurs. Over time, how would the genetic variation look within each population of lizards (would it increase or decrease)? Now imagine you have sandy beaches that are inhabited by populations of crabs that are red or yellow or green. Somehow one of the beaches becomes more and more filled with golden sand while the others stay multicolored. Over time, how would the genetic variation look between the populations on the beaches?arrow_forwardWhat is evolutionary fitness?arrow_forward
- Explain why the statement, “organisms evolve in response to a change in an environment” is a common misconception in evolution.arrow_forwardAccording to Darwin’s model of evolution, evolution can only occur if there is some variation present among the individual members of a population. Which statement best describes the source of this variation among members of a species? A) individuals will vary depending on geography and climate B) variation exists because not all genes will be expressed C) variation among individuals may arise as a result of mutations in the genetic code D) variation exists because different individuals will have different access to food and other resourcesarrow_forwardExplain gene flow as a force of evolution (how does gene flow contribute to biological change?)arrow_forward
- Why are only inherited variations important in the evolutionary process? Explain your answer.arrow_forwardWhat is meant by biological evolution?arrow_forwardAn hypothesis for the extinction of the dinosaurs is that the earth had been hit by a gigantic meteor that caused the death of those big reptiles. In that case the entire genetic pool of those animals has been destroyed, invalidating the Hardy-Weinberg equilibrium. In Genetics what is this type of gene frequency change called?arrow_forward
