When the genotype of an organism is improved by the addition of foreign gene, the process is called

Options

A. Tissue culture
B. Genetic diversity
C. Genetic enginerring
D. Plastic surgergy

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about a process where the genotype of an organism is improved by adding a foreign gene.

2. **Analyzing the Options**:
- **A. Tissue culture**: This is a technique used to grow cells in a controlled environment, but it does not involve adding foreign genes.
- **B. Genetic diversity**: This refers to the variety of genes within a species and does not pertain to the addition of foreign genes.
- **C. Genetic engineering**: This is the process of altering the genetic makeup of an organism by introducing new genes, which aligns with the question.
- **D. Plastic surgery**: This is a medical procedure for altering physical appearance and is unrelated to genetics.

3. **Identifying the Correct Answer**: Based on the analysis, the correct answer is **C. Genetic engineering**, as it specifically involves the addition of foreign genes to improve the genotype of an organism.

4. **Conclusion**: The process of improving the genotype of an organism by adding a foreign gene is known as genetic engineering.
