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.

Blending inheritance (or ‘soft inheritance’) A theory of inheritance first postulated by the French biologist Jean-Baptiste Lamarck (1744–1829) in which the hereditary substances from parents appeared to merge together in their offspring, and in which there is no apparent segregation in later generations.

Blending Theory of Inheritance. During Mendel's time, the blending theory of inheritance was popular. This is the theory that offspring have a blend, or mix, of the characteristics of their parents. Mendel noticed plants in his own garden that weren’t a blend of the parents.

In the mid-1800s, when Mendel was doing his experiments, most biologists subscribed to the idea of blending inheritance. Blending inheritance wasn't a formal, scientific hypothesis, but rather, a general model in which inheritance involved the permanent blending of parents' characteristics in their offspring (producing offspring with an ...

Mendel experimented with the inheritance of traits in pea plants at a time when the blending theory of inheritance was popular. This is the theory that offspring have a blend of the characteristics of their parents.

Contemporary theories of “blending inheritance” proposed that offspring merely struck an average between the characteristics of their parents. But as Darwin became aware, blending inheritance (including his own theory of “pangenesis,” in which each organ and tissue of an organism throws off tiny contributions of itself that are…

2020年1月21日 · Blending vs Particulate inheritance The once prevalent (but now discredited) concept of blending inheritance proposed that some undefined essence, in its entirety, contained all of the heritable information for an individual.

2018年5月21日 · blending inheritance An inheritance in which the characters of the parent appear to blend to form an intermediate state in the offspring, and in which there is no apparent segregation in later generations.

2014年6月1日 · With blending inheritance, the “amount of variation present in a sexually reproducing random breeding population must be halved in every generation. Given a population which exhibits a large variability at the start, we are bound to observe a progressive, rapid, and irretrievable decay of the variability, until a complete homogeneity is reached.”

Model 8a: Blending inheritance. In Model 8a we will simulate blending cultural inheritance, inspired by a formal mathematical model presented by Boyd & Richerson (1985). We assume a population of \(N\) individuals. Each of these individuals possesses a value of a continuously varying cultural trait.
