The heterozygotes are made homozygotes through:

Options

A. Continuous out breeding
B. Continuous inbreeding
C. continuous mutations
D. Random mutations

Answer

To answer the question "The heterozygotes are made homozygotes through:", we need to analyze the options provided and understand the genetic principles involved.

### Step-by-Step Solution:

1. **Understanding Heterozygotes and Homozygotes**:
- Heterozygotes have two different alleles for a trait (e.g., Aa).
- Homozygotes have two identical alleles for a trait (e.g., AA or aa).

2. **Analyzing the Options**:
- **Option 1: Continuous Outbreeding**:
- Outbreeding involves mating individuals that are not closely related or have different traits. This process does not lead to homozygosity; instead, it maintains or increases heterozygosity.
- **Option 2: Continuous Inbreeding**:
- Inbreeding involves mating individuals that are closely related or have similar traits. This process can lead to the production of homozygotes from heterozygotes.
- **Option 3: Continuous Mutations**:
- Mutations are changes in the DNA sequence. They do not directly lead to homozygosity from heterozygosity.
- **Option 4: Random Mutations**:
- Similar to continuous mutations, random mutations do not facilitate the conversion of heterozygotes to homozygotes.

3. **Conclusion**:
- The only viable option that leads to the conversion of heterozygotes to homozygotes is **Option 2: Continuous Inbreeding**. By continuously inbreeding heterozygotes, we can increase the likelihood of producing homozygous offspring.

### Final Answer:
The heterozygotes are made homozygotes through **continuous inbreeding**.
