Allele g for fat production increases in a small population because birds with more bodyfat have higher survivorship in a harsh winter.b. Random mutation increases the frequency of allele A in one population but not inanother.c. Allele R reaches a frequency of 1.0 because individuals with genotype rr are sterile.d. Allele m is lost when a virus kills all but a few individuals and just by chance, none ofthe survivors possess allele m.
- Which of the following statements does NOT agree with the tenets of Darwin's theory of evolution by means of natural selection? O A. The phenotypes of individuals in a population will differ and, in some cases, these differences are the result of traits passed down from parent to offspring. B. Phenotypes become more common over time if individuals with those phenotypes have higher reproductive success. O C. The fitness of an individual with a particular phenotype is independent of the environmental conditions it experiences. O D. Resources limit the total number of individuals in a population.Which of the following DOES NOT alter a [population’s genetic composition? a. random mating b. natural selectionc. Inbreedingd. Gene flow from migration e. Genetic driftWhich of the following is Not required for Natural Selection to occur with a biological population? A. Not all offspring survive to reproduce B.Individuals is the population with some phenotypic variants must have higher fitness on average C. Individuals with one phenotype must always have more offspring than individuals with other phenotypes D. The phenotypical variation within a population of organisms must be heritable E. Variation in the phenotypes of organisms within a population
- Many species of birds choose their mates based on how brightly colored they are. If feather color is heritable, how would this violate the assumptions required for a population to be in Hardy-Weinberg equillibrium? HW equilibrium would cause mutations in such a species. A. This is a founder effect В. This is a bottleneck effect C. OD. Mating is non-random. Alleles for brightly colored phenotypes might become more common in the species and allele frequency would change.Which of the following will change genotypic frequencies in a population without also changing allelic frequencies? A. Mutation B. Natural selection C. Non-random mating D. Migration E. Genetic driftWhich of the following statements about natural selection is a misconception? a.Most species don't produce more offspring than the environment can support b.Natural selection acts on heritable variations in a population c.Natural selection involves differential reproductive success d.Natural selection occurs as a result of competition among individuals in a population e.In natural selection, traits that are favoured depend on current environmental conditions

Select one: А. It must be present in a population hefore natural selection can act the population. upon. В. It arises in response to changes in the environment. C. It tends to be reduced by the processes involved when diploid organisms produce gametes. D. It is created by the direct action of natural selection. E.
