Which of the following statements about evolution is incorrect? O Evolution occurs through natural selection Evolution is a gradual process that occurs over time in populations. Evolution is a goal-oriented process that aims to create perfect organisms designed to handle what the future environment might throw at it. Evolution is influenced by genetic variation within populations

Which of the following is NOT one of Darwin's postulates?   Individuals in a population will have different versions of phenotypic traits   Individuals in a population will vary in how successful they are with respect to survival and reproduction   Some phenotypic traits can be passed from parent to offspring   Individuals change in response to the environment, and pass those changes on to the next generation

Which of the following forces of evolution is considered purely random? natural selection non-random mating genetic drift O mutation O migration

Which of these is NOT an assumption made by HWE? Group of answer choices Mating is random No adaptation Infinitely large population No natural selection No mutation

natural selection is incorrect

What is the role of variation in evolution If heterozygosity is reduced what happens to the potential for evolution? The phenotype and genotype of a population is due to a mosaic of random and directed processes some of these have to do with history.some are related to adaptation etc. As completely as possible,discuss the role of chance and direction in evolution and in determining the phenotype of a population

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 is the hypothesis that individuals who possess favorable traits are more likely to survive and reproduce than those who possess less favorable traits?     genetic drift     gene flow     mutation     natural selection

In which population is evolution by natural selection most clearly demonstrated? Group of answer choices A virus sweeps through a population and makes everyone ill.  A virus sweeps through a population and kills 10% of infants. It is not clear why some die and some don't. A virus sweeps through a population and kills 20% of the population. It is not clear why some die and some don't. A virus sweeps through a population and permanently sterilizes the 10% of the population that has allele hx25c.

A massive mudslide takes out half of the trees growing on a mountain side. The trees that are left happen to have slightly thicker branches than the original population. Which type of mechanism evolution is this Natural Selection Genetic drift Gene Flow Bottleneck Effect Founder Effect Sexual Selection
