1. Based on this lab, describe how antibiotic resistance in bacteria may have evolved including the mutation that created the gene, how antibiotics can cause natural selection, how the genetics of the bacteria changes over time (resistant and non-resistant), and how the genetics and phenotypes of the host (resistant and non-resistant) changes over time.

2. If flower color in a plant population is due to 2 alleles (R = red and r= white) which show incomplete dominance (Rr = pink), in a population of 100 flowers:

A. In generation 1, what is the number of red and white alleles if the population consists of 20 red flowers, 50 pink flowers, and 30 white flowers (hint: multiply the number of individuals by the number of each allele in each of the genotypes).

B. In generation 2, what is the number of red and white alleles if the population consists of 60 red flowers, 20 pink flowers, and 30 white flowers?

C. How did the number of red and white alleles change from generation 1 and generation 2?

D. Did this population of flower evolve and explain the basis for you answer?
