Question

The genetic structure of an organism is called

• A. Phenotype
• B. Genotype
• C. Heredity
• D. Diversity

Hint:

A simple way to remember: Genotype is the genetic code. Phenotype is the physical appearance.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This question asks for the correct genetic term for the complete set of genes that an organism possesses.

Step 2: Detailed Explanation:
\[\begin{array}{rl} \bullet & \text{Genotype: This term refers to the genetic makeup of an organism. It describes the organism's complete set of heritable genes, or the alleles an individual has for a particular trait. For example, for the pea plant height trait, the genotype could be TT, Tt, or tt. } \\ \bullet & \text{Phenotype: This term refers to the observable physical or biochemical characteristics of an organism, as determined by both its genotype and environmental influences. For example, the phenotype for a pea plant with genotype TT or Tt is 'tall'. } \\ \bullet & \text{Heredity: This is the broader concept of the passing of genetic traits from parents to offspring. } \\ \bullet & \text{Diversity: This refers to the variation within a population or species. } \\ \end{array}\]

Step 3: Final Answer:
The genetic structure of an organism is called its genotype.
