How is the blending theory of inheritance useful in genetics?
makkiz [27]

Charles Darwin's theory of pangenesis, in which every part of the body contributes to an egg or sperm, implied blending inheritance. Darwin's theory of natural selection was founded on the premise that blending inheritance would average out any novel beneficial trait before selection could act.

As an example, a cross between a red flower variety and a white variety of the same species would result in pink-flowered offspring.
