His paper was published in the proceedings of the society the next year. From his breeding experiments with the edible pea, he recog­ nized the phenomena of what we call dominance and recessiveness, segregation of assortment of dif...

A.N. Kolmogorov’s defence of Mendelism

In 1939 N.I. Ermolaeva published the results of an experiment which repeated parts of Mendel's classical experiments. On the basis of her experiment she concluded that Mendel's principle that self-pollination of hybrid plants gave rise to segregation proportions 3:1 was false. The great probability theorist A.N. Kolmogorov reviewed Ermolaeva's data using a test, now referred to as Kolmogorov's,...

France in the era of Mendelism (1900-1930).

This paper describes and explains the reception of Mendelism among French biologists at the beginning of the 20th Century. Three dimensions of description must be taken into account: scholarly diffusion; transmission of the new science through teaching and textbooks; and effective research. These three axes of description do not provide the same picture: Mendelian research was widely reported a...

Commentary: A century of Mendelism: on Johannsen's genotype conception.

Herbert Spencer, ‘pangenes’ of de Vries and ‘bioblasts’ of Richard Altmann had been widely considered. The most elaborate 19th century theory of heredity and development was that of August Weismann who postulated the existence of a hierarchy of determinants, organized in chromosomes, which would segregate out of the cell nucleus in the course of development and determine cell types. Weismann’s ...
