Right from the beginning, genetics has been an international venture, with international networks involving the collaboration of scientists across continents. Janaki Ammal’s career illustrates this. This paper traces her scientific path by situating it in the context of her relationships with J. B. S. Haldane and C. D. Darlington. Keywords. science; empire; India.

Genetic experiments, guided by these principles, C. D. Darlington (Harman 2004). expanded rapidly in the years between 1900 and 1921. The results of these studies provided a solid conceptual framework into which subsequent results could be fitted.
