Evolutionary fitness refers to? the contribution an individual makes to the gene pool of the next generation the ability of an organism to survive in a particular environment Othe ability of an organism to adapt to changing environmental conditions
Fred and George are arguing over evolution. Fred posits that evolution can occur in any population as long as all members gradually undergo change. George disagrees; he thinks that individual memebers of the population do not change but instead have offspring with the trait(s) of interest and thus a population evolves over generations. Who is right? Choose the best answe a. Fred is right! As members of the population respond to the environment, they change to suit it better O b. Fred is right! All memebers of the population must change aroudn the same time O c. George is right Evolution occurs over generations as only the beneficial traits are passed onto the next generation. O d. George is right! Individuals don't change their alleles, but the offspring they have contributes to the change in population allele frequencies
Mutations O do not cause evolutionary change. O occur because an organism has a need. O do not lead to adaptation. O result in genetic variation.
Background: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question. Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________. What goes in the blank

The reason spontaneous mutations do not have an immediate effect on allele frequencies in a large population is that: a. mutations are random events, and mutations may be eitherbeneficial or harmful. b. mutations usually occur in males and have little effect oneggs. c. many mutations exert their effects after an organism hasstopped reproducing. d. mutations are so rare that mutated alleles are greatlyoutnumbered by nonmutated alleles. e. most mutations do not change the amino acid sequence of aprotein.
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
