In Morgan's linkage experiments on Drosophila recombinants percentage for white eye and yellow body is:
Show Hint
- 37.2%
- 1.3%
- 62.8%
- 98.7%
The Correct Option is B
Solution and Explanation
Step 1: In Morgan's linkage experiments with Drosophila, the white eye (w) and yellow body (y) traits are inherited in a linked manner. This means that these genes are located on the same chromosome and are usually inherited together, but recombination can occur between them during meiosis.
Step 2: The recombinant percentage refers to the percentage of offspring that exhibit a new combination of traits not seen in the parents. In Morgan's experiment, the recombination between the white eye and yellow body genes resulted in a 1.3% recombinant frequency, indicating that these two genes are closely linked.
Step 3: A recombinant frequency of 1.3% is relatively low, which supports the idea that the genes are tightly linked, meaning that crossover events between them occur less frequently.
Conclusion: The correct percentage of recombinants for white eye and yellow body in Morgan's experiment is 1.3%.
