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 a 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

norm of reaction

Step-by-step explanation:

norm of a reaction which is the capacity of a genotype to produce different phenotypes in response to the environment. The group of phenotypic expressions under different environmental conditions. A organism can own all the genetic complements necessary to fully development. However, if there is no suitable nutricion, the development does not occur. The environment only changes the phenotypic characteristics within certain limits ruled by the genotype (norm of reaction). The genotype do not determine a phenotypes, but a amount of possible phenotypes, a norm of reaction. A certain phenotype will  materialize itself depending on the interaction of a certain genotype with the environment.

the correct answers i think are b. and d.

give me brainliest if it is correct!

just keep asking questions until you have a better understanding.
