Medical Genetics 1. Variability and Gene(or Allelic) Frequencies 1. Genetic data for a population can be expressed as gene or allelic frequencies 2. All genes have at least two alleles; 3. Summation of all the allelic frequencies for a population can be considered a description of the population; 4. Frequencies can vary widely among the alleles In a population; 5. Two populations of the same species do not have to have the same allelic frequenciesMedical Genetics 1. Variability and Gene (or Allelic) Frequencies 1.
