Questions and Answers

What is the study of genetic variability within a population and the evolutionary forces that act on it called?

  • Genomic sequencing
  • Genetic drift
  • Population genetics (correct)
  • Population dynamics

    • In population genetics, what does genotype frequency refer to?

  • The proportion of a particular phenotype in a population
  • The proportion of genetic variability in a population
  • The proportion of a particular genotype in a population (correct)
  • The proportion of a specific allele in a population

    • According to the Hardy-Weinberg Principle, what is one of the conditions for allele frequencies to remain constant from generation to generation?

  • Gene flow allows new alleles to enter or exit the population
  • New alleles are continuously generated by mutation
  • Organisms preferentially mate based on their genotypes
  • All alleles confer equal fitness and survival advantage (correct)
