If there is complete linkage in

Options

A. `F_(2)`generation
B. Parental types and recombinants appear in equal ratioo
C. Recombinants are less than parental types
D. Recombinants are more than parental types

Answer

**Step-by-Step Solution:**

1. **Understanding Complete Linkage:**
- Complete linkage occurs when two genes are located very close to each other on the same chromosome. This proximity means that they are rarely separated during the process of crossing over in meiosis.

2. **Characteristics of Complete Linkage:**
- In complete linkage, the alleles of the linked genes tend to be inherited together. This results in a higher frequency of parental type offspring compared to recombinant types.

3. **Analyzing the Options:**
- **Option 1: F2 Generation** - This option is incorrect because the concept of complete linkage does not specifically refer to the F2 generation.
- **Option 2: Parental Type and Recombinant Appear in Equal Ratios** - This is also incorrect as, in complete linkage, the parental types outnumber the recombinants.
- **Option 3: Recombinants are Less than Parental Type** - This option is incorrect because it suggests that recombinants are fewer, which contradicts the definition of complete linkage.
- **Option 4: Recombinants are More than Parental Type** - This is the correct option. In complete linkage, the recombinants are indeed more than parental types.

4. **Conclusion:**
- Based on the analysis, the correct answer is that in the case of complete linkage, recombinants are more than parental types.
