Question

The lack of linear correlation between the genome sizes and genetic complexities among various species is known as

• A. C-value paradox
• B. Genetic diversity
• C. G-value paradox
• D. Central dogma

Hint:

C-value paradox → genome size vs complexity. G-value paradox → gene count vs complexity.

Answer 1

The Correct Option is A

Step 1: Understand the concept.
The G-value paradox refers to the observation that the number of protein-coding genes does not correlate with an organism’s biological complexity.
Step 2: Compare with similar terms.
- C-value paradox: Relates to total DNA content not correlating with complexity.
- G-value paradox: Refers specifically to number of genes.
Thus, the observed lack of correlation between gene number and complexity is due to alternative splicing, regulatory sequences, and noncoding RNAs.
Step 3: Conclusion.
Hence, the correct term is G-value paradox.
