In Mendel’s day, many people thought that offspring inherited a blend of their parents’ traits. For example, they thought that an animal with white fur and an animal with black fur would produce offspring with grey fur. This is called the blending theory of inheritance. How did Mendel show that the blending theory was incorrect?

Answer:
The blended inheritance hypothesis suggests that physical traits (or phenotypes) of offspring are an intermediate of the parents. For example if a tall man and a short woman have a child, this hypothesis predicts their child would have a height intermediate relative to her parents.

Blending inheritance is an obsolete theory in biology from the 19th century. The theory is that the progeny inherits any characteristic as the average of the parents' values of that characteristic. As an example of this a crossing of a red flower variety with a white variety of the same species would yield pink-flowered offspring.

His reliance on this mechanism led Fleeming Jenkin to attack Darwin's theory of natural selection on the grounds that blending inheritance would average out any novel beneficial characteristic before selection had time to act.
