The linked characters would always inherit together till they are

Options

A. Delinked due to segregation
B. masked by dominance
C. Mutated
D. Separated due to crossing over

Answer

To answer the question "The linked characters would always inherit together till they are," we need to understand the concept of linked genes and how they behave during inheritance.

### Step-by-Step Solution:

1. **Understanding Linked Genes**:
- Linked genes are genes located close to each other on the same chromosome. Because of their proximity, they tend to be inherited together during meiosis.

2. **Concept of Crossing Over**:
- During meiosis, homologous chromosomes can exchange segments in a process known as crossing over. This can separate linked genes if the genes are far enough apart on the chromosome.

3. **Types of Linkage**:
- There are two types of linkage:
- **Complete Linkage**: When two genes are very close together, crossing over is unlikely to occur, and they are inherited together.
- **Incomplete Linkage**: When two genes are farther apart, crossing over can occur, leading to the possibility of separating the linked genes.

4. **Identifying the Correct Answer**:
- The question asks when linked characters will stop inheriting together. The correct answer is when they are "separated due to crossing over." This implies that if crossing over occurs, the linked genes can be separated and will not be inherited together.

5. **Final Answer**:
- Therefore, the linked characters would always inherit together until they are **separated due to crossing over**.
