To W. B. Tegetmeier 27 [December 1862]
Summary
CD interested in hybrid sterility and encloses his preliminary MS. Outlines experiments to test for existence of sterility in breeds of poultry and pigeons.
Experiments on dimorphism have led him to change in part his opinion as given in Origin, and he is now asking pigeon and poultry fanciers for any examples of special selective sterility [i.e., a particular pair are sterile when crossed, but each individual is fertile with others] and hopes to investigate its inheritance.
