Genetic Studies on a Cavy Species Cross (Classic Reprint)

Book excerpt: Excerpt from Genetic Studies on a Cavy Species Cross The genetic studies herewith presented were made possible for the author, by the reception of the foundation stock, in December 1909, from Dr. W. E. Castle. The first crosses had been made in 1903, and about 200 of the wild and intense wild-blooded hybrid animals had been born when the stock was received. The birth records, the weights, and such skeletons as had been saved, as well as the living hybrids, were made available to the author, who here expresses his gratitude for the privilege of using this material and for generous assistance, which was never withheld. He also wishes to acknowledge the valuable aid Of Mr. Elmer Roberts, in the preparation Of the manuscript.
