blending inheritance: meaning, definition, pronunciation and examples

It was not proposed by a single individual but was a common, intuitive assumption held by many scientists and breeders prior to Gregor Mendel's work in the mid-19th century.

As a complete theory of heredity, it is incorrect. However, some observable traits (like skin colour in some simplified models) can appear to 'blend,' though this is actually the result of the interaction of multiple particulate genes, not a true blending of hereditary material.

Incomplete dominance (e.g., a red and white flower producing a pink offspring) is a specific genetic phenomenon where the heterozygous phenotype is intermediate. 'Blending inheritance' was a universal theory predicting all traits would blend irreversibly across generations, losing variation.

Understanding blending inheritance highlights the significance of Mendel's particulate theory. It serves as a classic case study in the history of science, illustrating how a paradigm shift occurs when an old model fails to explain empirical data.

A historical biological theory stating that the characteristics of offspring result from a direct blending or averaging of their parents' traits.
