What is Darwinian Population Genetics?
When Charles Darwin proposed his theory of evolution in 1859, one of his main problems was the lack of a genetic underlying mechanism. Darwin believes in a mixture of inherited and acquired traits (pangenesis). Mixed inheritance will only lead to population unification across generations and then eliminate mutations in groups where natural selection may play a role. This led Darwin to adopt some Lamarckian ideas in later "Origin of Species" and later biological works. Darwin's main approach to heredity is to outline how it works (note that traits not explicitly expressed by parents during reproduction can be inherited, some traits may be sex-related, etc.) rather than a underlying mechanism.

- Mixed inheritance is a biological theory proposed in the 19th century. The theory holds that the offspring inherited all the traits of the parent, that is, the average of the parents' performance on the trait. For example, a cross between a red variety and a white variety of the same flower will produce a pink flower offspring.
- The theory of pangenetic genetics proposed by Charles Darwin suggests mixed inheritance by describing the contribution of parts of the body to eggs or sperm. His mechanism led Fleeming Jenkin to attack natural selection, arguing that mixed genetics would dilute any novel beneficial traits before there was time for natural selection.
- After 1900 [1] , in the development process of modern genetics, Mendelian genetic theory was generally accepted, thus giving up mixed inheritance.
