Which of the following is NOT one of the three features of evolution by natural selection? Offspring tend to resemble their parents because of heredity. O Individuals in populations show variation in their phenotypes. O Organisms can induce the phenotypic changes they need to survive and reproduce in a given environment. Some individuals survive and reproduce better than others, because of their phenotypes.

What is the role of variation in evolution. If heterozygosity is reduced, what happens to the potential for evolution?. The phenotype and genotype bof a population is die to a mosaic of random and directed processes, some of them 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
Four of the five factors below support the mechanism of natural selection. In contrast, the fifth factor blocks natural selection from occurring. Which one of the factors listed below does NOT lead to natural selection, but instead stops it from occurring? O Characteristics are inherited - passed from parent to offspring. O Organisms in a population are identical to each other. O There is competition among organisms in a population. O More offspring are born than can survive. O Organisms in a population vary in characteristics that affect how well they survive and reproduce. o o oO
Which of the following is likely to be most important in the evolution of two species from one population of another species? O some kind of barrier that physically divides the original species into two sub-populations a change in the environment such that one sub-population experiences differential natural selection O reduced performance of gametes (e.g., pollen) in crosses between sub-populations O reduced fitness of offspring resulting from crosses between sub-populations genetic divergence and cessation of gene flow between sub-populations
Which of the following is not true of natural selection? (a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traits acquired during an individuals lifetime (d) natural selection acts on a populations genetic variability, which arises through mutation (e) natural selection may result in changes in allele frequencies in a population
Which the following statements about Darwin's theory of natural selection is true? O In order to reproduce more successfully, an individual must evolve so that it adapts to its environment. The natural environment consistently causes variation of certain traits in the population. O Individuals with inherited traits that are better suited to the local environment are more likely to survive and reproduce than less well-suited individuals. Natural selection, by its cumulative effects over long periods of time, could have caused random changes in ancestral species, thus giving rise to two or more descendant species.
Which of the following is NOT principle of Darwinian evolution? OOffspring resemble their parents more closely than unrelated individuals. Darwinian evolution fully describes where all living things come from. O In any given environment, some individuals are more successful at surviving and reproducing than others. There is variation in morphology, physiology, and behavior among individuals in a population.
Which of the following best describes natural selection? O It is a guess made by scientists about how life develops, but it has no hard evidence to support it. It is the idea that the strong survive and the weak die off. It is the idea that organisms with genetic traits that improve their ability to reproduce are more likely to pass those traits on to future generations. It is the idea that organisms naturally increase in complexity and intelligence with time.
Which of the following statements about natural selection is not true? O Natural selection operates according to differential reproductive success of individuals. O Natural selection usually predominates in small population only. O The cumulative effects of natural selection gives rise to individuals that can survive in a specific environment. O Natural selection results in evolution when individuals with higher survival and reproductive rates pass on these traits to their offspring.
Which of the following is true about natural selection? O It can only act on traits that are heritable and show variation. It always favors large, strong individuals. It allows species to choose what adaptations are passed on to offspring. O It acts on individual organisms, helping them become better adapted to their environment.
In order for evolution to occur via natural selection on a particular trait, which of the following must be present for that trait? Which out of the 4 answers below is correct? Only 1 answer is correct Variation, mutations, fitness consequences Variation, fitness consequences, mode of inheritance Genetic recombination, variation, mutations Mutations, fitness consequences, mode of inheritance
In a population of lizards, color is genetically determined. The current population has two two phenotypes: blue and yellow. Which of the following scenarios could result in evolution by migration? O A disease indiscriminately reduces the population by 90%. Birds are better able to see and therefor prey on blue lizards The population is joined by individuals from a nearby population that has an allele for a red phenotype. Females preferentially mate with individuals exhibiting the blue phenotype.
