Comprehension Passage
Mendel's inheritance experiments with pea plants demonstrated the basic principles of genetic inheritance. When Mendel crossed tall and dwarf pea plants, he observed that all the first generation (F1) progeny were tall, indicating the dominance of the tall trait. No intermediate heights were observed, showing no blending of traits.
While Mendel's principles laid the foundation for understanding genetics, later studies revealed complexities beyond his findings. Linked genes on the same chromosome can be inherited together, challenging Mendel's rule of independent assortment.
In Antirrhinum (Snapdragon), a red flower was crossed with a white flower and in the F1 generation, pink flowers were obtained. When pink flowers were selfed, the F2 generation showed white, red, and pink flowers. Choose the incorrect statement from the following :
1
This experiment does not follow the Principle of Dominance.
2
Pink colour in F1 is due to incomplete dominance
3
Ratio of F2 is \(\frac{1}{4}\) (Red) : \(\frac{2}{4}\) (Pink) : \(\frac{1}{4}\) (White)
4
Law of Segregation does not apply in this experiment
