Book excerpt: Excerpt from Studies of Inheritance in Guinea-Pigs and Rats For several years I have been engaged in studies of heredity in guinea-pigs. In the course of these studies all the common varieties of guinea-pigs have been investigated by the method of experimental breeding and something has been learned concerning their inter relationships and probable mode of origin. The actual origin of most Of these varieties is, however, unknown, as is true also concerning most varieties of domesticated animals. One or two varieties have, however, been made synthetically in the laboratory and it is conceivable that, if we had the original wild stock to work with, from which the domesticated guinea-pig has arisen, some or all Of the existing varieties might be synthesized anew and perhaps still others might be Obtained, and that in this way something might be learned of the method by which new varieties arise. From considerations such as these I have for several years been seeking to obtain living specimens Of the wild species which most closely resemble guinea-pigs. In 1903 I received from Campinas, Brazil, 3 wild - caught individuals referred at the time to the species Cam'a aperea, but Since found to agree better with the description Of C. Rufescens. From two of these animals young were Obtained, and crosses, the results of which have been described in detail by Dr. Detlefsen were made with domesticated guinea pigs. It may be noted that all male F1 hybrids were sterile, but that the PI females were fertile, and that upon repeated crossing Of these with male guinea-pigs, a race Of fertile hybrids was at last obtained, these being, in the language of breeders, about guinea-pig, firufescens. From this result it seems doubtful whether C. Rufescens has any close genetic relationship to the domesticated guinea-pig, although by hybridization it has been found possible to produce races (g or more guinea-pig) which have derived certain characters from a rufescens ancestor.

Available in PDF, EPUB and Kindle. Book excerpt: Dr. Castle's paper treats of an ancestral or atavistic coat-character of the guinea-pig present in most wild rodents but frequently absent in their tame varieties and which may be obtained by crossing certain domesticated varieties of guinea-pig. A full account is given of how the reversion in question may be secured, how its reappearance can be accounted for, and in what way the recovered character may be "fixed" or reestablished as a racial character together with the complete data which form the basis of this account. Dr. Little analyzes the observed phenomena of color inheritance in mice on the basis of Mendelian heredity and shows the relations of the various factors involved in the production of colors, to each other and to the coat and eye colors produced. The paper includes the analysis and description of the color factors and gives the experimental data on which the conclusions are based. -Classified First of Publications of the Carnegie Institution of Washington [1918]

Book excerpt: Excerpt from Selection and Cross-Breeding in Relation to the Inheritance of Coat-Pigments and Coat-Patterns in Rats and Guinea-Pigs It is generally agreed that the course of evolution is largely influenced by two factors, variation and heredity; but opinions differ as to what sorts of variation have evolutionary significance and as to the manner of their inheritance.
