- major ways a population can evolve - Correct Answer gene flow, genetic drift, natural
selection
Adaptation - Correct Answer Allele change that increases the fitness of a population
Allele Frequency - Correct Answer Divide number of a specific allele by the total number of alleles in a population Allele B Frequency = Number of Allele B / Total Allele Population
Antibiotic - Correct Answer A medicine that kills or slows the growth of microorganisms
Artificial Selection - Correct Answer Type of "natural selection." When humCorrect Answer select the traits they want in animals and plants.
Bacteria - Correct Answer A large group of single-celled microorganisms. Very diverse, found almost everywhere on earth
Change in Allele Frequency - Correct Answer If some alleles become more common over time, it's an indicator evolution has occurred
Diploid - Correct Answer Cell that has two sets of DNA chromosomes. Both cats & humCorrect Answer are examples of diploid organisms
directional selection - Correct Answer Happens when one extreme trait is favored
Disruptive Selection - Correct Answer When both extreme traits are more favorable.Both increase fitness & become more common in the distribution graph
Distribution of a Trait - Correct Answer Natural selection can change the distribution of a trait in one of three ways: directional selection, stabilizing selection, disruptive selection
Evolution - Correct Answer A change in the traits of a population over time. Traits are characteristics like looks or behaviors. Traits come from types of genes called alleles. If the alleles change, so do the traits
Fitness - Correct Answer how well an organism can survive and reproduce in its environment
Founder Effect - Correct Answer When a small number of individuals (the founders) leave a population & start a new one
Gene Flow - Correct Answer Changes allele frequencies when individuals move between populations. Can happen between 2 different species of bacteria
