21. Population Genetics

In a population at Hardy-Weinberg equilibrium, if the frequency of the g allele is 0.6, what percentage of all alleles in the population are g?

Biologists have proposed that the use of antibiotics to treat human infectious disease has played a role in the evolution of widespread antibiotic resistance in several bacterial species, including Staphylococcus aureus and the bacteria causing gonorrhea, tuberculosis, and other infectious diseases. Explain how the evolutionary mechanisms mutation and natural selection may have contributed to the development of antibiotic resistance.

If the Hardy-Weinberg equilibrium is met in a population, what is the net effect?

In a population at Hardy-Weinberg equilibrium with an allele frequency of q = 0.25 for a recessive allele, what is the expected frequency of heterozygotes?

Which of the following statements is NOT a part of the Hardy–Weinberg principle?

In the Hardy-Weinberg equation, what does the letter q represent?
