Describe how a population may develop drug resistance
I know it’s Mutation, adaptation, survival, reproduction, change in allele frequency but idk how to word it for 4 mark question
It needs to be detailed and mine are so short

A random mutation in the DNA leads to drug resistance. Exposure to the drug acts as a selection pressure where only the individuals with the advantageous drug resistance allele can survive and successfully reproduces, passing down the advantageous drug resistance allele to their offspring. Overtime, the frequency of the drug resistance allele increases until it becomes a common allele.
I'm guessing this is about bacteria and antibiotic resistance in which case you could also mention that they can transfer the antibiotic resistance allele to other bacteria via conjugation.
