When two different genotypes due to differetn environmental conditions give rise to same phenotype, the condition is called

Options

A. Phenocopies
B. Consanguinity
C. Complementation
D. Penetrance

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a term that describes the phenomenon where two different genotypes produce the same phenotype due to varying environmental conditions.

2. **Analyzing the Options**:
- **Phenocopies**: This term refers to a phenotype that mimics another phenotype but is caused by environmental factors rather than genetic factors.
- **Consanguinity**: This refers to the genetic relationship between individuals who share a common ancestor.
- **Complementation**: This occurs when two different genetic mutations result in a normal phenotype when crossed.
- **Penetrance**: This describes the proportion of individuals with a specific genotype that express the associated phenotype.

3. **Identifying the Correct Term**:
- The description in the question aligns with the definition of **phenocopies**. This is because phenocopies occur when different genotypes (e.g., Himalayan rabbits and genetically black rabbits) exhibit the same phenotype (black coat) due to environmental influences (cold temperature).

4. **Conclusion**: Therefore, the correct answer to the question is **phenocopies**.
