- What is disruptive selection ?arrow_forwardIn what way is artificial selection different from natural selection?arrow_forwardDarwin 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?arrow_forward

- How is selective breeding similar and different from natural selection?arrow_forwardWhat is the principle of natural selection?arrow_forwardNatural 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 organismsarrow_forward
- Sexual selection tends to cause bigger size,more elaborate weaponry, or brighter colors in males. Is this an example of stabilizing,directional, or disruptive selection?arrow_forwardConsider the four postulates of natural selection. How have humans manipulated each of these postulates in natural or artificial systems?arrow_forwardIs natural selection working mainly in the phenotype or the genotype? Are the individuals or the population evolving?arrow_forward
