  • Q2
    a measure of how common a certain allele is in the population
    Allele frequency
    30s
  • Q3
    The gradual change in a species over time
    Evolution
    30s
  • Q4
    fundamental processes or natural phenomenon that are capable of altering gene frequency in populations and as a result are responsible for evolutionary change; these mechanisms include natural selection, mutations, gene flow, genetic drift, and recombination, etc.
    Evolutionary mechanisms
    30s
  • Q5
    movement of alleles from one population to another
    Gene flow
    30s
  • Q6
    A change in the allele frequency of a population as a result of chance events rather than natural selection.
    Genetic drift
    30s
  • Q7
    A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.
    Natural Selection
    30s
  • Q8
    Random errors in gene replication that lead to a change in the sequence of nucleotides. The source of all genetic diversity.
    Mutations
    30s
  • Q9
    The regrouping of genes in an offspring that results in a genetic makeup that is different from that of the parents.
