Read the following statements and choose the correct option ( with reference to Mendel's monohybrid cross).
Statement 1 :- Only one of the parental traits was expressed in the F1 generation.
Statement 2 :- In the F2 stage both the traits were expressed in the ratio 3:1.

Both the statements are correct.

The correct option is: Both statements are correct.

• Statement 1: Only one of the parental traits being expressed in the F1 generation is consistent with Mendel's principle of dominance, where the dominant trait masks the expression of the recessive trait.
• Statement 2: In the F2 generation of Mendel's monohybrid cross, both parental traits reappear in a ratio of 3:1, demonstrating the segregation and independent assortment of alleles, with three individuals exhibiting the dominant trait and one individual displaying the recessive trait.

In the F2 generation, both parental traits of a character appear in a ratio of three dominant to one recessive. In the F1 generation, only one of the parental traits is visibly expressed while the other remains latent. There is no blending of the two traits in the hybrid. During gamete formation, the two factors segregate and move independently into different gametes, each containing one factor from the pair. Upon fertilization, random fusion of gametes results in the recombination of factors in the new generation, allowing them to express themselves independently.
