Which of the following is NOT required for adaptations to evolve Heritable variation in fitness O Genetic diversity within populations Sexual reproduction Natural selection

natural selection is incorrect

Which of the following evolutionary mechanisms can drive genetic divergence after the genetic isolation created by allopatry or sympatry? Select ALL that apply. 08 Natural selection Mutation Gene flow Genetic drift

An animal born with a shorter tail. This makes no difference to its ability to survive or reproduce, but as a result of pure luck, the animal survives, reproduces, and passes its shorter tail down to its offspring. Over time, the species develops a shorter tail. What type of process is described in this scenario? genetic modification artificial selection genetic drift natural selection

Which of these evolutionary processes can increase allelic variation in the population? O Mutation Natural Selection Artificial selection Sexual selection

A farmer wants to make a better corn plant that produces more and bigger kernels. In the chart, information is provided on two ways organisms can change over time. Natural Selection Selective Breeding Humans are not involved in the evolution process Human intervention is involved More generations are involved in natural selection, so it is a slower process Selective breeding is a faster process Survival of the fittest increases species' chance for survival Adaptations may not necessarily improve survival Mutations that result in natural selection occur randomly The desirable charactenstics are artificially chosen What is the best way for the farmer to improve his crop and why? Use evidence from the table to support your reasoning. Please write in complete sentences.

Which of the following are accurate descriptions of natural selection? Select all that apply. •It selects for traits that increased the complexity of the organism . ���It creates genetic variation. •It creates physical variation. •It selects for traits that helps organisms reproduce most successfully.
