Theory of blending inheritance
WebbThe curious case of blending inheritance For more than a century, geneticists have consistently identified the origins of their science with Gregor Mendel's experiments on peas. Mendelism, they have said, demonstrated at long last that biological inheritance was not, as had so often been supposed, "blending," but particulate. Many historia … WebbThese factors may be genetic, environmental, or both. Polygenic inheritance. Some characteristics are polygenic, meaning that they’re controlled by a number of different genes. In polygenic inheritance, traits often form a phenotypic spectrum rather than falling into clear-cut categories. Environmental effects.

Blending Inheritance A blending of the characteristics of the parents resulting in the offspring Doesn’t preserve genetic variation over time! Mendelian Inheritance Preserves genetic variation over time! WebbBlending inheritance was the common ideal at the time, but was later discredited by the experiments of Gregor Mendel. Mendel proposed the theory of particulate inheritance by using pea plants ( Pisum sativum) to explain how variation can be inherited and maintained over time.
