Select the incorrect statement

Options

A. Inbreeding helps in accumulation of superior genes and elimination of undesirable genes
B. Inbreeding increases homozygosity
C. Inbreeding is essential to evolve purelines in any animal
D. Inbreeding selects harmful recessive genes that reduce fertility and productivity

Explanation

To solve the question "Select the incorrect statement," we will analyze each of the four statements provided regarding inbreeding and its effects.

### Step-by-Step Solution:

1. **Analyze Statement 1**: "Inbreeding helps in accumulation of superior genes and elimination of undesirable genes."
- **Explanation**: This statement is correct. Inbreeding often leads to the concentration of desirable traits and the removal of undesirable traits through selective breeding.

2. **Analyze Statement 2**: "Inbreeding increases homozygosity."
- **Explanation**: This statement is also correct. Inbreeding tends to increase homozygosity, which means that the offspring are more likely to inherit the same alleles from both parents, leading to a uniform genetic makeup.

3. **Analyze Statement 3**: "Inbreeding is essential to evolve pure lines in any animals."
- **Explanation**: This statement is correct as well. Inbreeding is often necessary to establish pure lines, which are crucial for maintaining specific traits in breeding programs.

4. **Analyze Statement 4**: "Inbreeding selects harmful recessive genes that reduce fertility and productivity."
- **Explanation**: This statement is incorrect. Inbreeding does not select harmful recessive genes; rather, it tends to expose these genes, and through selection, they are often eliminated from the breeding population.

### Conclusion:
The incorrect statement is **Statement 4**: "Inbreeding selects harmful recessive genes that reduce fertility and productivity."

### Final Answer:
The correct answer is **Statement 4**.
