Does the glu– allele ever confer a disadvantage?
In the presence of poison-laced glucose, cockroaches that refuse glucose will have a much higher survival rate than cockroaches that feed indiscriminately. This explains why the glu– allele frequency increases over time in a population exposed to poison + glucose bait. However, energy from carbohydrates is required for growth and reproduction, and glucose is commonly found in non-po
