Given a 10% per site mutation rate, how many sites do you predict will have a mutation? Show your calculations or provide support for your response. The average mutation rate was estimated to be approximately 2.5 x 10^-8 mutations per nucleotide site or 175 mutations per diploid genome per generation. As the rate of mutation is increase in parents that will reflected in progeny the offspring will have some defects in body plan. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation but if mutation in germ cell it pass into next generation. The source of genetic variation in a population is mutation. Mutation rates in humans have been estimated to be on the order of 10^-4 to 10^-4 per gene per generation. How many mutated sites did you observe your Avidian's offspring to actually have?

Given a population size of 100,000,000 (108) and a mutation rate of 0.001% calculate the number of expected mutants. Under what circumstances will these mutations increase in the population? Decrease? Remain constant?

Mutations are introduced into the E. coli genome at the rate of about 1 mutation per 10^9 base pairs (bp) per generation. Imagine that you start with a population of 10^6 E. coli cells, none of which carry any mutations in your gene of interest (which is 1000 nucleotides in length and not essential for bacterial growth and survival). In the next generation, after the population doubles in number, what fraction of the cells, on average, would you expect to carry a mutation in your gene? After the population doubles again, what would you expect the frequency of mutants in the population to be? What would the frequency be after a third doubling? How are mutation rate and mutation frequency related to each other?
