To help your investigation, here is some more data about the farm.The chicken population was started with chicks from a different farm.Chickens are raised in barns where bacteria can spread easily between chickens.CJ, E. Coli, and Salmonella bacteria are all present in the barns.Some of the E. Coli and Salmonella bacteria have alleles that make them resistant to the FQ antibiotic.To stop disease from growing in the barn, the FQ antibiotic is fed to the chickens a lot.Choose which way of evolution caused the FQ antibiotic resistance.Gene FlowGenetic DriftNatural SelectionWhat is the best fit option here? Form a hyptothesisThis is my hypothesis, is it right ?If the chicken population is consistently given the FQ antibiotic, then natural selection leads to antibiotic resistance, because some chickens could have some of the bacterias that develop mutations allele and they can resist against FQ antibiotics.Bacteria which are resistant will continue to increases and grows in number over time. In the end, the chicken population are mainly resistant bacterial, thus making this the likely mechanism of evolution.
