The Avy allele of the Agouti gene involves the insertion of a transposable element upstream from the normal Agouti promoter. Let’s suppose that pregnant female mice are fed a diet that contains chemicals that increase DNA methylation. With regard to offspring carrying the Avy allele, this diet would

The process is a utility providing hot water to a plant. The setpoint is the temperature of the hot water utility. The disturbances are system throughput and utility demand changes. Which is likely to be the more important control objective for this process: setpoint tracking or disturbance rejection.
