The correct Answer is:
To solve the matching question regarding chromosomal mutations, we need to analyze each term in Column I and find the correct corresponding term in Column II. ### Step-by-Step Solution: 1. **Identify Tetrasomy (a)**: - Tetrasomy refers to a condition where there are four copies of a particular chromosome instead of the normal two. This means there is a gain of two extra chromosomes. - Therefore, Tetrasomy corresponds to **(iv) 2n + 2**. 2. **Identify Double Trisomy (b)**: - Double Trisomy is a condition where there are three copies of two different chromosomes. This can be expressed as an increase of two chromosomes in total (one extra for each of the two chromosomes). - Thus, Double Trisomy corresponds to **(v) 2n + 1 + 1**. 3. **Identify Hypoploidy (c)**: - Hypoploidy is a condition where there are fewer chromosomes than the normal diploid number. This typically means one less chromosome than normal. - Hence, Hypoploidy corresponds to **(ii) 2n - 1**. 4. **Identify Allopolyploidy (d)**: - Allopolyploidy occurs when an organism has more than two paired (homologous) sets of chromosomes derived from different species. This is typically represented by the combination of two different species' chromosome sets. - Therefore, Allopolyploidy corresponds to **(i) AABB**. ### Final Matching: - a. Tetrasomy → (iv) 2n + 2 - b. Double Trisomy → (v) 2n + 1 + 1 - c. Hypoploidy → (ii) 2n - 1 - d. Allopolyploidy → (i) AABB ### Summary of Matches: - a - (iv) - b - (v) - c - (ii) - d - (i)
