The correct Answer is:
To solve the question of selecting the correct statement regarding genetic linkage and recombination, we will analyze each statement provided in the options. ### Step-by-Step Solution: 1. **Examine the First Statement:** - **Statement:** Tightly linked genes on the same chromosome show higher recombination. - **Analysis:** Tightly linked genes are those that are located close to each other on the same chromosome. Due to their proximity, they tend to be inherited together and do not undergo recombination frequently. - **Conclusion:** This statement is **incorrect**. 2. **Examine the Second Statement:** - **Statement:** Genes far apart on the same chromosome show very few recombinations. - **Analysis:** Genes that are located far apart on the same chromosome are more likely to undergo recombination due to the increased chance of crossing over occurring between them. - **Conclusion:** This statement is **incorrect**. 3. **Examine the Third Statement:** - **Statement:** Genes loosely linked on the same chromosome show similar recombination as the tightly linked genes. - **Analysis:** Loosely linked genes are those that are farther apart on the chromosome and therefore have a higher chance of recombination compared to tightly linked genes. - **Conclusion:** This statement is **incorrect**. 4. **Examine the Fourth Statement:** - **Statement:** Tightly linked genes on the same chromosome show very few recombinations. - **Analysis:** This statement accurately reflects the behavior of tightly linked genes. They are less likely to be separated during recombination events, resulting in fewer recombinations. - **Conclusion:** This statement is **correct**. ### Final Answer: The correct statement is: **Tightly linked genes on the same chromosomes show very few recombinations.** ---
