The correct Answer is:
To solve the question, "Haploids are more suitable for mutation studies than the diploids. This is because," we will analyze the options provided and determine the correct answer step by step. ### Step 1: Understand the Definitions - **Haploid (N)**: A cell or organism that has a single set of chromosomes. - **Diploid (2N)**: A cell or organism that has two sets of chromosomes, one from each parent. ### Step 2: Analyze the Options - **Option A**: "Haploids are more abundant in nature than diploids." - This statement is not necessarily true. While some haploid organisms exist, diploids are more common in many species, especially in higher plants and animals. - **Option B**: "All mutations whether dominant or recessive are expressed in haploids." - This statement is true. In haploids, there is only one set of chromosomes, so any mutation, whether dominant or recessive, will be expressed directly. - **Option C**: "Haploids are reproductively more stable than diploids." - This statement is misleading. Diploids often have more genetic stability due to having two copies of each gene, which can mask harmful mutations. - **Option D**: "Mutagens penetrate in haploids more effectively than in diploids." - This statement lacks sufficient evidence and is not a commonly accepted reason for the suitability of haploids in mutation studies. ### Step 3: Determine the Correct Answer Based on the analysis, **Option B** is the correct answer. Haploids are more suitable for mutation studies because all mutations, whether dominant or recessive, are expressed in haploids due to the presence of only one set of chromosomes. ### Conclusion Thus, the final answer is: **B. All mutations whether dominant or recessive are expressed in haploids.** ---
