A. No, because there isn't a genetic basis for inheritance between parent and offspring virus particles. B. No, because there isn't a way to distinguish more fit from less fit virus particles C. Yes but only via human (domestic/artificial) selection D. No they evolve by mutations. E.

- Mutation is the only evolutionary mechanism that: A. always causes decreased fitness B. is not mentioned by the Hardy-Weinberg model C. is more important in eukaryotes than in prokaryotes D. does little to change allele frequencies on its own E. has no effect on genetic variation.arrow_forwardEvolutionary change caused by natural selection results in species witha. greater complexity.b. less complexity.c. greater reproductive success in their native environment.d. the ability to survive longer.arrow_forwardScientists have concluded that the AS genotype as an adaptation for survival in Africa. Support the conclusion in terms of natural selection A. The frequency of the AS allele increases proportionately to the number of Africans in the population B. Because Malaria does not exist in the U.S and the AS allele does not provide any advantage to survival there. C. As the frequency of Malaria increases so does the frequency of the AS allele combination as it protects against getting Malaria D. Those without the AS genotype die out due to sickle cell disease; the populations left with a greater allelic frequency of the AS genotypearrow_forward
