Natural Selection This is the selection of fit alleles in a population. Evolution This is considered to be a change in the allele frequency or a change in genetic structure of a popu… Hardy-Weinberg Principle (or Equilibrium) This concept has been reached when a population is large, mating is random, no selection occurs, no … Allele This is a specific expression for a gene. Genetic Drift This is the fluctuation in the allele frequency of a population due to chance events. It especially … Bottleneck Effect This occurs when a population suffers heavy loss of life and experiences a drop in genetic variation. Polyploidy This condition is best described as an increase in chromosome sets.
