At 6,000 calories a day, a person with genotype x will weigh 285 lbs with much energy and high cholesterol levels. at 3,500 calories per day, the person will weigh 200 lbs with much energy and slightly elevated cholesterol levels. at 1,800 calories a day, the person will weigh 175 lbs with little energy and low cholesterol levels. these are examples of that genotype’s

The correct answer is "norm of reaction".

Explanation:

Genotype's norm of reaction is a curve that describes the contributions of the environmental factors into the phenotype. In this example, the most likely phenotype of people consuming different number of daily calories intakes are described. These are examples of genotype's expected norms of reaction, using the daily calories intakes as the environmental factor and the weight as the expected phenotype.
