Had Mendel decided to study those traits together which are determined by linked genes, he would not have found out:

Options

A. Law of segregation
B. Law of dominance
C. Low of independent assortment
D. Low of unit character

Answer

To answer the question, we need to understand the concepts of linked genes and the laws of inheritance proposed by Mendel. Here’s a step-by-step solution:

### Step 1: Understand Mendel's Laws
Mendel formulated several key principles of inheritance, including the Law of Segregation, the Law of Dominance, and the Law of Independent Assortment. Each of these laws describes how traits are inherited from parents to offspring.

### Step 2: Define the Law of Independent Assortment
The Law of Independent Assortment states that alleles for different traits segregate independently of one another during gamete formation. This means that the inheritance of one trait does not influence the inheritance of another trait.

### Step 3: Introduce the Concept of Linkage
Linkage refers to the phenomenon where genes that are located close to each other on the same chromosome tend to be inherited together. This means that if two genes are linked, they do not assort independently, which contradicts Mendel's Law of Independent Assortment.

### Step 4: Analyze the Implication of Studying Linked Genes
If Mendel had studied traits determined by linked genes, he would have observed that these traits do not assort independently. This would lead him to conclude that the Law of Independent Assortment does not apply to linked genes.

### Step 5: Conclusion
Therefore, had Mendel decided to study those traits together which are determined by linked genes, he would not have found out the Law of Independent Assortment, as the existence of linkage contradicts this law.

### Final Answer
Had Mendel decided to study traits determined by linked genes, he would not have discovered the Law of Independent Assortment.
