Short Answer

Expert verified
Answer: B. phenotype

Step by step solution

01

Understand the terms

To find the correct term for Jenny's characteristics, it's important to know the meaning of each term provided in the problem: A. genotype: This is the genetic makeup of an individual. B. phenotype: This represents the observable physical and biological traits of an individual that result from the interaction between their genotype and the environment. C. somatotype: This refers to the classification of the body into one of three types - ectomorph, mesomorph, and endomorph - based on an individual's physique and body composition. D. physiognomy: This is the practice of assessing someone's character or personality from their outer appearance, especially the face.
02

Analyze the terms and Jenny's characteristics

We need to find the correct term for Jenny's given characteristics - brown hair, blue eyes, and height. These features are all observable physical traits which result from the interaction of her genes and the environment.
03

Identify the correct term for Jenny's characteristics

Since Jenny's characteristics are related to her observable physical traits, the correct term for her in this case is "phenotype" (Option B). This fits because the phenotype is the closest description of Jenny's characteristics among the given options. Therefore, the correct answer is: B. phenotype.
