Two or more alternative (different) forms of a gene is referred to as: Question 12 options: allele genotype phenotype gene

Break Down the Problem

1. Identify the question type: The question is asking for the definition of a biological term related to genetics.
2. Analyze the provided options: Understanding what each option means will help find the correct answer.

Relevant Concepts

1. Allele: Different forms of a gene that can exist at a specific locus on a chromosome.
2. Genotype: The genetic constitution of an individual, representing the combination of alleles.
3. Phenotype: The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.
4. Gene: A segment of DNA that is responsible for a specific trait.

Analysis and Detail

• Alleles are crucial for genetic variation and can determine characteristics such as eye color or blood type.
• By contrast, genotype refers to the specific alleles an organism possesses, while phenotype refers to how those alleles are expressed physically.

Verify and Summarize

Upon analyzing the definitions, the correct term for two or more alternative forms of a gene is allele.

Final Answer

allele
