Question

How did the monohybrid crosses performed 2by Mendel refute the blending concept of inheritance?

Answer 1

Mendel’s monohybrid crosses refuted the blending theory by showing that traits are inherited as discrete units (genes) and do not blend. In the F₁ generation, the recessive trait disappeared but reappeared unchanged in the F₂ generation in a 3:1 ratio. This demonstrated that hereditary factors remain separate and pure during inheritance, contradicting the blending concept where traits would mix and dilute over generations.
