Researchers discovered that a new strain of bacteria that causes tuberculosis (M. tuberculosis) has a point mutation in the rpoB gene that codes for part of the RNA polymerase enzyme. This mutant form of RNA polymerase does not function as well as the more common form of RNA polymerase. A commonly used antibiotic called rifampin does not affect the mutant rpoB bacteria.A researcher mixes M. tuberculosis with and without the rpoB mutation and adds the bacteria to cell cultures. Half the cell cultures contain only standard nutrients, while the other half of the cell cultures contain rifampin and the standard nutrients. After many cell generations, you might expect the researcher to find________.

A zombie apocalypse wipes out almost the entire human species before the zombie threat is eliminated. Only a group of 100 people who were at a family reunion on an uninhabited island survived. They returned to the mainland completely unaware of what had happened to everyone. Certain traits will have been lost from the gene pool forever. This loss of diversity in a reduced population is called

People with cystic fibrosis (CF) are homozygous recessive for mutations in a gene known as CFTR. These mutations cause the CFTR protein to become dysfunctional, and it is unable to move chloride to the cell surface. Ultimately mucus can build up in organs, and in the lungs, the mucus clogs the airways and traps bacteria, leading to infections, inflammation, and respiratory failure. In a human population, if 9 in 10,000 newborn babies are born with CF, what are the expected frequencies of the dominant (A1) and recessive (A2) alleles according to the Hardy-Weinberg model in that population?
