QuestionAnswer
Explain the significance of gene pools in understanding evolution. Without the gene pool there would be no variation of any gene for it to be able to adapt.
Tell how genetic drift, gene flow, mutation, and natural selection contribute to changes in a gene pool. They all contribute by effecting the alleles and how common they each show up.
Explain what is meant by the term fitness. contribution that an individual makes to the gene pool of the next generation compared to the contributions of other individuals
Describe recent evidence for microevolution on the Galápagos Islands. The size of the finches beaks on the Galapagos Island changes from year to year based on what food is available for the finches to eat.
gene pool all of the alleles in all the individuals that make up a population
micro-evolution evolution on the smallest scale—a generation-to-generation change in the frequencies of alleles within a population
Hardy-Weinberg equilibrium condition that occurs when the frequency of alleles in a particular gene pool remain constant over time
genetic drift change in the gene pool of a population due to chance
gene flow exchange of genes between populations
fitness contribution that an individual makes to the gene pool of the next generation compared to the contributions of other individuals
