Mendelian dihybrid and dihybrid with linkage are respectively realated with how many chromosomes :-

Options

A. 1 pair & 2 pair
B. 2 pair & 1 pair
C. 2 pair & 2 pair
D. 1 pair & 1 pair

Answer

To solve the question regarding how many chromosomes are related to Mendelian dihybrid and dihybrid with linkage, we can break it down into clear steps:

### Step 1: Understand Mendelian Dihybrid
- Mendelian dihybrid refers to a genetic cross involving two traits, each represented by two alleles. In this case, we are dealing with two different genes.
- These two genes are located on different chromosomes. Therefore, a Mendelian dihybrid involves two pairs of chromosomes.

### Step 2: Understand Dihybrid with Linkage
- Dihybrid with linkage refers to a situation where two genes are located on the same chromosome and are inherited together due to their proximity.
- In this case, since both genes are on the same homologous chromosome, it involves one pair of chromosomes.

### Step 3: Summarize the Findings
- From the above understanding:
- Mendelian dihybrid is related to **two pairs of chromosomes** (since it involves two different genes on different chromosomes).
- Dihybrid with linkage is related to **one pair of chromosomes** (since it involves two genes on the same chromosome).

### Step 4: Choose the Correct Option
- Based on the analysis:
- The correct answer is that Mendelian dihybrid relates to **two pairs of chromosomes** and dihybrid with linkage relates to **one pair of chromosomes**.

Thus, the correct option is the second one: **two pairs for Mendelian dihybrid and one pair for dihybrid with linkage**.
