- "evolution is an integrated process" and uses sickle-cell allele as an example. In just 2-3 sentences, trace the various factors that influence evolution based on this example. I just want to know how Darwin, Mendel, gene flow, genetic drift, mutation, recombination and even the environment serve to create evolution. Thank you.In your group, consider the following statement: "Mutations are random, natural selection is not." What does that statement mean?Imagine a population of mice living in a grey, rocky environment. Some mice are grey and some are brown. If natural selection occurs in this population, what would you expect to see if you returned in 100 mouse generations? Describe what you'd see in terms of fur colors in the population. Imagine a population of mice living in a grey, rocky environment. Some mice are grey and some are brown. If mutations occur in this population, what could you see if you returned in 100 mouse generations, that would tell you mutations had occurred? Describe what you'd see in terms of fur colors in the population, and how it would be different from what you'd see in #2.
- can you describe an example of natural selection? your example can be real or imaginary. just be sure to tell us whether it is true or not!Darwin proposed natural selection as a mechanism for evolution. How is it similar to artificialselection? How is it different? For natural selection to work, there must be genetic variation within a population as well asmutations? Why must there be both?What is the difference between natural selection and sexual selection?In one sentence each, identify the similarities and the differences between artificial selection and natural selection.
- According 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 matingWhat is the relationship between artificial selection and natural selection?Darwin proposed natural selection as a mechanism for evolution. How is it similar to artificial selection? How is it different?For natural selection to work, there must be genetic variation within a population as well as mutations? Why must there be both?
- 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 organismsExplain how it is that natural selection doesn't act on genes?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.
