Bio unit 7 quiz

Population refers to a group of individuals of the same species living in the same area and interbreeding to produce fertile offspring. Gene pool refers to a population's genetic makeup consisting of all copies of every type of allele.

<p>The Hardy Weinberg principle is a model used to assess whether natural selection or other factors are causing evolution at a particular locus. Five conditions must be met to be in Hardy Weinberg equilibrium: no mutations, random mating, no natural selection, extremely large population size, and no gene flow.</p> Signup and view all the answers
