Which statement about breeding is wrong

Options

A. by inbreeding pure lines cannot be evolved
B. increases production
C. increases beef production
D. increases milk production

Answer

### Step-by-Step Solution

1. **Understanding Breeding**: Breeding is a method used to produce new individuals by crossing different species or varieties. It can involve inbreeding (crossing closely related individuals) or outbreeding (crossing unrelated individuals).

2. **Analyzing the First Statement**: The first option states, "by inbreeding, pure lines cannot be evolved." Inbreeding involves mating closely related individuals over several generations (typically 4 to 6). This process is known to produce pure lines, which are genetically uniform with minimal variation.

3. **Conclusion on the First Statement**: Since inbreeding does indeed lead to the evolution of pure lines, the statement that "pure lines cannot be evolved" is incorrect. Therefore, this statement is the wrong one.

4. **Reviewing Other Options**: The video mentions that breeding can increase the production of beef, milk, and other products. It also discusses the Multiple Ovulation Embryo Transfer (MOET) technique, which enhances herd improvement by increasing the number of eggs produced by females through hormonal treatment, leading to higher productivity.

5. **Final Answer**: The wrong statement about breeding is the first option: "by inbreeding, pure lines cannot be evolved."
