17. There are many sources of genetic variation among living organisms. Mutations, or changes to an organism's genetic material, are a significant source of genetic variation. Sexual reproduction. results in an offspring that has a combination of genetic material from its parents, which contributes to genetic variation. Meiosis

Natural selection occurs only if there is both (1) variation in the genetic information between organisms in a population and (2) variation in the expression of that genetic information—that is, trait variation—that leads to differences in performance among individuals. (HS-LS4-2) LS4.C: Adaptation

The Hardy-Weinberg equation is “p2+2pq+q2=1” and it is used to calculate the genetic variation of a population at equilibrium by calculating the frequency of the alleles in the population. Which part of the equation represents: the homozygous dominant, the heterozygotes, and the homozygous recessive? The heterozygotes is represented by ...
