Galton's rather different derivations of the law in 18 are described, and their shortcomings are discussed in the light of these results (Galton, 1885, 1897). Natural inheritance by Galton, Francis, Sir, 1822-1911 Publication date 1889 Topics Heredity Publisher London and New York : Macmillan and co. The former equation reduces to Galton's ancestral law when the proportion of latent elements is 0.5, the latter when this proportion 0.6. Galtons ancestral law states that the two parent contribute between them on average one-half of the total heritage of the offspring, the four grandparents. The equation representing ancestral contributions to the heritage of the offspring differs from the multiple regression equation for predicting the value of a trait from ancestral values.

The resulting law has a free parameter to be empirically estimated which represents the frequency of latent hereditary elements that are not expressed in a particular individual but are capable of transmission to the next generation. Logical reconstruction of the law is presented based on formalizing Galton's model of heredity outlined in Natural Inheritance (Galton, 1889). The former equation reduces to Galtons ancestral law when the proportion of latent elements is 0.5, the latter when this proportion 0.6. Galton used statistical methods and propounded a law.

He interpreted this law both as a representation of the separate contributions of each ancestor to the heritage of the offspring and as a multiple regression formula for predicting the value of a trait from ancestral values. The equation representing ancestral contributions to the heritage of the offspring differs from the multiple regression equation for predicting the value of a trait from ancestral values.
