Question

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

○ adaptive capacities.

○ environment.

○ norm of reaction.

○ this has nothing to do with the genotype..

Explanation:

The "norm of reaction" refers to the range of phenotypic expressions a genotype can produce under different environmental conditions. Here, the same genotype (genotype X) shows different phenotypes (weight, energy, cholesterol) based on calorie intake (environment). "Adaptive capacities" focus on survival advantages, "environment" is the external factor (not the genotype’s trait), and the last option is incorrect as the data relates to genotype - environment interaction.

Answer:

C. norm of reaction.
